To assist in the identification of larvae and juveniles, specimens were skeletonized (removal of tissues, muscles, and organs) was performed on adult specimens of + +B. juruense + +( +Figure 2a–b +), allowing the counting of vertebrae and consequently comparison with the myomere count of the larvae. Additionally, for this study, individuals of the other + +Brachyplatystoma +species + +were analyzed for the number of vertebrae, the quantity of which corroborated with +Lundberg & Akama (2005) +. This procedure is required for understanding the adult characteristics such as the numbers and position of spines and rays in all fins. Vertebral counts include all elements of the Weberian complex (four vertebrae); the compound center of the caudal skeleton is counted as one element. + + +The larvae and juveniles were identified according to the regressive development sequence technique proposed by +Ahlstrom & Moser (1976) +. This technique consists of identification based on a sequence of individuals at different stages, from juveniles or larvae in more advanced stages to less developed larvae, based on morphological, meristic, and morphometric characteristics. Firstly, with the aid of a stereomicroscope, juvenile specimens were identified by comparing their fin ray information and morphology, which are consolidated at this developmental stage. Following the identification of juveniles, the process continues with the analysis of larvae, where similarities to juveniles’ characteristics are observed, thereby justifying the use of the term regressive sequence. Subsequently, individuals were classified according to the degree of development, following Ahlstrom +et al +. (1976) modified by + +Nakatani +et al +. (2001) + +, into larval period (flexion and postflexion) and juvenile period. + + + +FIGURE 2. + +Brachyplatystoma juruense + +(410.00 mm SL). (a) After collection in the natural environment and (b) After skeletonization. Vertebra count = 58 elements. Scale bar = 10 mm. + + + + +Description of larvae and juveniles of + +Brachyplatystoma juruense + + + + +The description was based on the degree of development (developmental stages) and observation of the main morphological events, as well as meristic and morphometric characters. For each period and stage, individuals that best represented the characteristics were photographed and illustrated, following the technique described by +Faber & Gadd (1983) +and +Shibatta (2016 +, +2017 +). + + +For the morphometric characterization of initial development, the following body measurements, expressed in millimeters (mm), were used: head depth (HD), body depth (BD), head length (HL), snout length (SNL), standard length (SL), eye diameter (ED), and snout length to the origin of the anal (SNA), dorsal (SND), pectoral (SNP), and pelvic (SNV) fins, according to Ahlstrom +et al +. (1976). Additionally, finfold depth in the posterodorsal region (adipose fin—AFD), snout length to the end of the anus (SNAN), finfold length in the posterodorsal region (adipose fin—AFL), interorbital distance (ID), and head width (HW) were measured. Morphometric measurements (in millimeters) were performed using a binocular stereomicroscope (Leica S9i—precision 0.01) coupled with a digital camera for image capture and analysis—(Leica LAS EZ software). For meristic characterization, the number of pre-anal (PAM), post-anal (PSM), and total (TM) myomeres, as well as the number of rays and spines in the pectoral (P), pelvic (V), dorsal (D), anal (A), and caudal (C) fins, were counted when possible. Only the main rays of the upper and lower lobes of the caudal fin were considered ( +Figure 3a–c +). + + + +Data analysis + + + +For the analysis of morphometric proportions (expressed as percentages), the variables HD, SNL, and ED were related to head length, while BD, HL, SNAN, SNA, SND, SNP, and SNV were related to standard length. Additionally, the variables DI and AFD were related to head width and finfold length in the posterodorsal region (adipose fin), respectively, to better understand the morphometric proportions throughout the initial development of + +B. juruense + +. The body proportions for body depth (BD/SL), head length (HL/SL), and eye diameter (ED/HL) were established using the criteria suggested by Leis & Trinski (1989). We considered the short anus range for individuals with SNAN <50% of SL and the long anus range when SNAN ≥ 50% of SL. The adipose fin was considered low when AFD <30% of SNAN and high when AFD ≥ 30% of SNAN, and the interorbital distance was classified as narrow when ID <40% of HW and wide when ID ≥ 40% of HW. + + + +FIGURE 3. +Morphometric measurements in + +Brachyplatystoma juruense + +.

The hypothesis of continuous isometric growth was tested through a simple linear regression model. In addition, alternative hypotheses were tested: gradually allometric growth (quadratic regression) and discontinuous isometric growth (piecewise regression). The ideal models for each morphometric variable related to the standard length and head length were determined through F-tests. The significance level adopted was p <0.05 (Sokal & Rolf 1981; L’avrinčíková +et al +. 2005).

+ + + +Morphological characterization of the larval period + + + +Flexion stage +( +Figure 4a, b, c +): The standard length ranges from +3.93 to 9.23 mm +(n = 35; mean: +6.76 mm +± +1.48 mm +). The notochord is visible through transparency and has its final section flexed due to the formation of the hypural plate and caudal-fin rays. The body has a fusiform shape. The mouth is located in a terminal position, the snout is rounded, and the nostril is paired, with a distal tubular shape. The eye is small (6.53% of HL), spherical, and pigmented. The operculum is visible. There are three pairs of barbels: one pair of maxillary barbels developing on the side of the head near the corner of the mouth (premaxillary), and two pairs of mental barbels located on the ventral region of the head, below the lower jaw. At the beginning of the flexion stage, both pairs of barbels extend to the stomach, not reaching the anus, while at the end of flexion, the maxillary barbels extend to the anal fin, and the two pairs of mental barbels reach the anus. The length from snout to anus is short (46.10% of SL), not reaching the mid-body region. At +3.93 mm +SL, pigmentation is restricted to dendritic chromatophores located at the base of the mental barbels and in the isthmus. From 5.00 mm SL onwards, the dorsal region of the head begins to show pigmentation. The finfold surrounds the body dorsoventrally and, towards the origin of the adipose fin, it has a relatively high triangular shape (>30% of SNAN). The pectoral-fin bud appears from 5.00 mm SL, and the first rays emerge at +7.68 mm +SL. The caudal fin initially has a heterocercal shape, but becomes bifurcated at +7.68 mm +SL, with the first two rays of the upper lobe larger than the others, forming a long filament. The number of myomeres varies from 58 to 59 (mode = 59) (22 pre-anal and 36 to 37 post-anal). + + +Postflexion stage +( +Figure 4d, e, f +): The standard length ranges from +9.50 to 19.99 mm +(n = 51; mean: +14.04 mm +± +2.93 mm +). At the beginning of the stage, the pelvic-fin bud emerges. The characteristics related to body shape, mouth, snout, nostril, eye, operculum, and anus reach remain similar to the flexion stage. The maxillary barbels and the lateral mental barbels, at +12.82 mm +SL, extend beyond the caudal peduncle and have different lengths, with the maxillary barbels being longer and the medial mental barbel extending beyond the anal fin. At +19.19 mm +SL, plates containing numerous villiform teeth are visible on the premaxilla and dentary. The coloration pattern is similar to the previous stage; however, a greater quantity of irregular dendritic and punctate chromatophores can be observed in the occipital region of the head, snout, base of the maxillary barbels, dorsal fin, and origin of the adipose fin. Additionally, filiform pigments are found along the first rays of the upper and lower lobes of the caudal fin. The finfold is partially absorbed, leaving only remnants in the anterior region of the anal and adipose fins. The adipose fin is triangular and depth, representing more than 30% of its base. The pectoral fin has a serrated spine, and in the dorsal fin, the first ray surpasses the height of the spine. The first ray of the lower lobe of the caudal fin modifies to form a long filament, similar to the upper lobe. At +19.99 mm +SL, the fin rays are not fully formed. The total number of myomeres is 59 segments (22 pre-anal and 37 post-anal). + + + +Morphological characterization of the juvenile period + + + +The standard length ranges from +20.33 to 25.77 mm +(n = 5; mean: +22.21 mm +± +2.32 mm +). These individuals are characterized by the complete formation of all structures (e.g., teeth, fins and rays). The mouth is terminal, and the head is dorsoventrally flattened. Pigmentation consists of irregular dendritic and punctiform chromatophores distributed as follows: (1) in the dorsal and lateral region of the head; (2) up to the halfway point of the maxillary barbels; (3) in the dorsal region of the body, concentrated below the dorsal and adipose fins; (4) on the spine and the first rays of the dorsal fin; (5) on the hypural plate; and (6) at the base of the caudal-fin rays and along the first rays of the upper and lower lobes of the caudal fin. The dorsal fin is located anterior to the vertical passing through the origin of the pelvic fin. The adipose fin is located anterior to the vertical passing through the origin of the anal fin. The caudal fin is elongated, bifurcated, and pointed, with long filaments at the tips of the upper and lower lobes. The rays of all fins are fully formed and segmented, including branching and the appearance of ceratotrichia. + + +The number of spines and rays of the fins is: dorsal I + 6, anal 18, pectoral I + 11, pelvic I + 5, and caudal II + 14 principal rays ( + +Figure +4g + +, +Table 1 +). + + + +Morphometric relationships + + + + +Brachyplatystoma juruense + +has a small eye (4.02% to 11.17% of HL) and a narrow interorbital distance (30.59% to 37.78% of HW). The head varies from moderate to large (20.99% to 41.36% of SL), the body from long to moderate (10.82% to 28.08% of SL), the reach of the anus short (42.24% to 47.93% of SL), and the finfold in the dorsoposterior region (adipose fin) high (32.15% to 46.33% of SNAN). Body proportions including snout length, head length, and the distances from snout to pectoral, anal, dorsal, and pelvic fins increased throughout development ( +Table 1 +). + + + +FIGURE 4. +Early development of + +Brachyplatystoma juruense + +: (a) Early flexion larvae—3.96 mm SL, (b) Flexion larvae—5.29 mm SL, (c) End flexion larvae—7.68 mm SL, (d) Early postflexion larvae—9.50 mm SL, (e) Postflexion larvae—12.82 mm SL, (f) End postflexion larvae—19.19 mm SL, and (g) Juvenile—25.77 mm SL. Bars = 1 mm. + + + + +Body growth + + + +The initial growth is distinct for different body parts of + +B. juruense + +. The eye grows at a faster rate compared to the head (ED/HL). This indicates that + +B. juruense + +prioritizes the development of its eye, characterized by positive allometric growth (quadratic regression) ( +Table 2 +, +Figure 5a +). For the head length (HD/HL) and body height (BD/ SL), as well as the lengths of the snout (SNL/HL) and head (HL/SL), growth was discontinuous isometric (piecewise regression). Initially, these body parts grow proportionally to the HL and SL until the end of the postflexion stage, at which point there is an abrupt change (breakpoint) in growth rates, resulting in alterations in relative proportions as + +B. juruense + +develops. The growth rates for HD, BD, and HL decreased, indicating that these structures grow slowly in postflexion (after the breakpoint). However, for SNL, the growth rates increased, meaning that the snout develops more rapidly, demonstrating priority in the growth of this structure in postflexion ( +Table 2 +, +Figure 5b, c, d, e +). The snout length to the pectoral (SNP), anal (SNA), dorsal (SND), and pelvic (SNV) fins grows proportionally to SL during all stages of development, following a pattern of continuous isometric growth (simple linear regression). Thus, the relative size of these body parts remains constant throughout the early development of + +B. juruense + +( +Table 2 +, +Figure 5f, g, h, i +). + + + + \ No newline at end of file diff --git a/data/0E/3A/61/0E3A61104A087444FFCACD02456CA65C.xml b/data/0E/3A/61/0E3A61104A087444FFCACD02456CA65C.xml new file mode 100644 index 00000000000..68f477287fe --- /dev/null +++ b/data/0E/3A/61/0E3A61104A087444FFCACD02456CA65C.xml @@ -0,0 +1,203 @@ + + + +Improved diagnostic sensitivity of human strongyloidiasis using point-of-care mixed recombinant antigen-based immunochromatography + + + +Author + +Boonroumkaew, Patcharaporn +Department of Parasitology, Faculty of Medicine, Khon Kaen University, 40002 Khon Kaen, Thailand & Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand + + + +Author + +Sadaow, Lakkhana +Department of Parasitology, Faculty of Medicine, Khon Kaen University, 40002 Khon Kaen, Thailand & Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand + + + +Author + +Janwan, Penchom +Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand & Department of Medical Technology, School of Allied Health Sciences, Walailak University, 80161 Nakhon Si Thammarat, Thailand & Hematology and Transfusion Science Research Center, Walailak University, 80161 Nakhon Si Thammarat, Thailand + + + +Author + +Rodpai, Rutchanee +Department of Parasitology, Faculty of Medicine, Khon Kaen University, 40002 Khon Kaen, Thailand & Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand + + + +Author + +Sanpool, Oranuch +Department of Parasitology, Faculty of Medicine, Khon Kaen University, 40002 Khon Kaen, Thailand & Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand + + + +Author + +Buadee, Punyisa +Department of Parasitology, Faculty of Medicine, Khon Kaen University, 40002 Khon Kaen, Thailand & Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand + + + +Author + +Suprom, Chanida +Department of Parasitology, Faculty of Medicine, Khon Kaen University, 40002 Khon Kaen, Thailand & Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand + + + +Author + +Thanchomnang, Tongjit +Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand & Faculty of Medicine, Mahasarakham University, 44000 Maha Sarakham, Thailand + + + +Author + +Intapan, Pewpan M. +Department of Parasitology, Faculty of Medicine, Khon Kaen University, 40002 Khon Kaen, Thailand & Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand + + + +Author + +Maleewong, Wanchai +Department of Parasitology, Faculty of Medicine, Khon Kaen University, 40002 Khon Kaen, Thailand & Mekong Health Science Research Institute, Khon Kaen University, 40002 Khon Kaen, Thailand + +text + + +Parasite + + +2023 + +Paris, France + + +2023-12-13 + + +30 + + +60 + + +1 +12 + + + + +http://dx.doi.org/10.1051/parasite/2023063 + +journal article +299946 +10.1051/parasite/2023063 +1c47b38b-4350-4042-aa32-d932c32cd64e +1776-1042 +PMC10723528 +38099622 +12524553 + + + + + + + +Strongyloides stercoralis + +recombinant antigens + + + + + + +The + +Strongyloides stercoralis + +L3NieAg.01 ( +NIE +) sequence (1–621 bp) deposited in the GenBank database (AF136445) was codon-optimized to be suitable for an + +Escherichia coli + +expression system and constructed into the pET22.b (+) vector (GenScript, Piscataway, NJ, +USA +).

These samples were therefore chosen for molecular screenings. In the case of the samples from +Austria +, the blood films were only available from a subset of individuals kept at the clinic.

Molecular characterisation of this pathogen was developed for the first time, linking + +H. nisi + +to the +cytb +lineage hACCNIS06. The main features of the blood stages of this lineage are as follows. + + +Macrogametocytes and microgametocytes grow around the nucleus of infected erythrocytes, they markedly enclose the nucleus with their ends but do not displace or only slightly displace it laterally ( +Figs. 1a–1h +). Young and growing gametocytes tend to not adhere to the erythrocytes’ nuclei ( +Figs. 1b, 1e +). The central part of the advanced growing gametocytes is closely appressed to the erythrocyte’ s envelope, but the ends of the gametocytes usually do not ( + +Figs. 1b, 1c, +1g + +). Advanced growing gametocytes often do not adhere to the erythrocyte’ s nucleus ( +Figs. 1b, 1e +), but forms adhering to the nucleus are also common ( + +Figs. 1c, 1f, +1g + +). Fully grown gametocytes are appressed to the nucleus and envelop of infected erythrocytes ( +Figs. 1d, 1h +); they are circumnuclear and often completely encircle the nucleus ( +Figs. 1d, 1h +) and can occasionally even occupy the entire cytoplasmic space in infected erythrocytes. The cytoplasm of the macrogametocytes is granular in appearance and contains a few small vacuoles ( +Figs. 1b, 1h +). Volutin granules are abundant and clumped; they obscure pigment granules ( +Figs. 1b–1d, 1f–1h +). The outline of the gametocytes varies markedly; it can be even, slightly wavy, or ameboid. The macrogametocytes’ nuclei are compact, variable in form, and median or sub-median in position ( +Figs. 1a, 1b +). The pigment granules are predominantly oval, sometimes roundish, of medium size (0.5–1 µm), randomly scattered throughout the cytoplasm. The configuration of microgametocytes ( +Figs. 1e–1h +) resembles that of the macrogametocytes with the usual sexual dimorphic characters, which are the paler stained cytoplasm, the diffuse centrally located nucleus and the predominant gathering of pigment granules close to the ends of the gametocytes ( +Figs. 1f–1h +).

Molecular characterisation of the parasite lineage hCIAE08 was developed for the first time. The main features of hCIAE08 blood stages are as follows. + + +Macrogametocytes and microgametocytes grow around the nucleus of infected erythrocytes, they markedly enclose the nucleus with their ends but do not displace or only slightly displace it laterally ( +Figs. 2a–2l +). The central part of the growing gametocytes predominantly adheres to the erythrocyte envelope but the ends of the gametocyte usually do not ( +Figs. 2c–2f, 2i–2k +); the advanced growing gametocytes tend to adhere to nuclei of infected erythrocytes ( +Figs. 2b, 2d +), but gametocytes not adhering to the nuclei were also seen ( +Figs. 2c, 2e, 2i +). Fully grown gametocytes are circumnuclear; they often nearly completely or completely encircle the nuclei ( +Figs. 2f–2h +) and can occasionally occupy the entire cytoplasmic space in infected erythrocytes. The cytoplasm of the macrogametocyte is heterogeneous in appearance and contains a few small vacuoles ( + +Figs. 2d, +2g +, 2l + +); volutin is present and seen as densely stained clamps of variable shape ( + +Figs. 2d, 2e, +2g +, 2h, 2i + +); the volutin might obscure the pigment granules, but not noticeably ( +Fig. 2h +). The outline of gametocytes varies markedly; it can be even, slightly wavy or ameboid. The nuclei of the macrogametocyte are compact, variable in form, and median or sub-median in position ( +Figs. 2c, 2d, 2h +). The pigment granules are roundish or oval, of medium size (0.5–1 µm), and randomly scattered throughout the cytoplasm ( +Figs. 2d, 2f, 2i, 2k +). The configuration of the microgametocytes ( +Figs. 2i–2l +) resembles that of the macrogametocytes with the usual sexual dimorphic characters, which are the paler stained cytoplasm, diffuse centrally located nuclei ( +Figs. 2i, 2l +) and the predominant gathering of pigment granules close to ends of the gametocytes ( +Figs. 2i, 2j, 2l +). Volutin is less evident in microgametocytes compared to macrogametocytes (compare + +Figs. 2e, +2g +, 2h and 2i + +). Voucher blood preparation of + +H. nisi + +lineage hCIAE08 (accession no.

Transmission probably occurs throughout the breeding range of + +B. buteo +. + +The lineage hBUBT1 was also found in five + +A. nisus + +individuals from +France +. However, the presence of gametocytes was not documented, so it remains unclear if the parasite completes the life cycle in this bird species. + + +Etymology: The species name reflects the markedly vacuolated appearance of the cytoplasm in both macrogametocytes and microgametocytes, resulting in minor differences between these +types +of gametocytes regarding the staining intensity (compare +Figs. 3e–3h +and +Figs. 3i–3p +). + + +Young gametocytes ( +Figs. 3a–3d +) were seen anywhere in infected erythrocytes but more often occupied polar or subpolar positions in the host cells ( +Figs. 3a, 3b +). As the gametocytes grow, they adhere to the nuclei of the erythrocytes and extend along the nuclei; they often assume asymmetrical positions regarding the nuclei, and this often leads to the appearance of comma-like gametocyte forms ( +Figs. 3c, 3d +). Growing gametocytes often do not adhere to the erythrocyte envelope ( +Fig. 3c +). + + + +Figure 2. + +Haemoproteus nisi + +(lineage hCIAE08) from the blood of Western marsh harrier + +Circus aeruginosus + +: a – young gametocytes, b–h – macrogametocytes, i–l – microgametocytes.

Simple wide long arrows – spaces between gametocytes and erythrocyte nuclei. Giemsa-stained thin blood films. Scale bar = 10 µm. + + + +Macrogametocytes ( +Figs. 3e–3h +; +Table 1 +) are markedly vacuolated, lack volutin granules, and the cytoplasm stains relatively pale in comparison to microgametocytes (compare +Figs. 3e–3h +and +Figs. 3i–3p +), which is a characteristic feature of this parasite. Gametocytes extend along nuclei of erythrocytes ( +Fig. 3e +); they markedly enclose the erythrocyte nuclei with their ends ( + +Figs. 3f, +3g + +) and finally completely encircle the nuclei ( +Fig. 3h +). Advanced and fully grown gametocytes are closely appressed to the nucleus and envelope of the erythrocytes; however, they usually do not fill poles of erythrocytes completely, resulting in the presence of more or less visible unfilled spaces on the poles ( +Figs. 3f–3h +). The outline of gametocytes is predominantly wavy, sometimes slightly ameboid or even. Parasite nucleus median or submedian in position, markedly variable in form and outline; its boundaries were poorly visible ( +Figs. 3e–3h +), which is a rare character in macrogametocytes of avian haemoproteids. Pigment granules are predominantly oval, sometimes roundish, of small (<0.5 µm) and average (0.5–1 µm) size, randomly scattered throughout the cytoplasm. Nuclei of infected erythrocytes only slightly displaced laterally ( +Figs. 3e–3h +); however, advanced growing gametocytes ( + +Figs. 3e– +3g + +) and fully grown gametocytes ( +Fig. 3h +) cause marked enlargement of infected erythrocytes in length ( +p +<0.01) and particularly in area ( +p +<0.001) in comparison to uninfected erythrocytes ( +Table 1 +), a characteristic feature of this species, which was readily recognisable in blood films even without statistical analysis (see + +Figs. 3e, +3g +, 3k, +3m + +for comparison of the size of the infected and uninfected erythrocytes). + + +Microgametocytes ( +Figs. 3i–3p +; +Table 1 +) are similar to macrogametocytes in general configuration and other features. Gametocyte nuclei are markedly diffuse, of irregular form. The outline of nuclei is poorly recognisable, so the nuclei were difficult to measure. + + + +Figure 3. + +Haemoproteus multivacuolatus + +n. sp. +(lineage hBUBT1) from the blood of the Common buzzard +Buteo buteo +: a–d – young gametocytes, e–h – macrogametocytes, i–p – microgametocytes. Long simple arrows – nuclei of parasites. Short simple arrows – vacuoles. Simple arrowhead – pigment granules. Triangle arrowheads – volutin granules. Note that due to marked vacuolisation, the cytoplasm of macrogametocytes stains relatively pale and looks similar to microgametocytes based on the intensity of staining. Giemsa-stained thin blood films. Scale bar = 10 µm. All images were from the hapantotype preparation. + + + +Taxonomic remarks: Four distinct morphospecies of + +Haemoproteus + +parasites were described in birds of the order +Accipitriformes +.

Slight enlargement of infected erythrocytes by fully grown gametocytes might occur in other haemoproteids, but this feature is not as distinct in other species parasitising accipitriform birds ( +Table 1 +). It is important to note that even growing gametocytes of + +H. multivacuolatus + +n. sp. +induce marked enlargement of infected erythrocytes ( +Figs. 3d, 3e +); that is not the case in any other haemoproteids parasitising accipitriform birds.

+ + +It is important to note that the identification of + +H. multivacuolatus + +n. sp. +might be difficult if only growing gametocytes are present in a sample. Such blood samples from + +B. buteo + +were common in this study. If parasitaemia is represented only by growing gametocytes ( +Figs. 3e, 3i–3k +) but fully grown (circumnuclear) gametocytes ( +Figs. 3h, 3o, 3p +) are absent, + +H. multivacuolatus + +n. sp. +identification might be difficult due to similarities with fully grown gametocytes of + +H. buteonis + +and + +H. elani + +.

[ +30 +] split + +D. varicus + +species complex into 4 groups: DV1–DV4. Bouguerche +et al +. [ +3 +] strongly showed that the DV1 clade is the “real” + +D. varicus + +and proposed to recognise it as + +D. varicus + + +s. s +. + +through the analysis of the 28S sequences of + +D. varicus + +from the type-host, the Atlantic salmon + +S. salar + +. Krupenko +et al +. [ +30 +] did not find any adult stages of DV +2 in +fish and hence could not provide further morphological comparison of DV1 and DV2. Additionally, the only available sequences of + +D. varicus + + +s. s +. + +from the type-host had been made available only recently [ +3 +]. Herein, the sequences of + +D. abba + +n. sp. +from Arctic + +H. platessoides + +were identical to those of + +D. varicus + + +s. l +. + +from the same host in the North Sea [ +50 +] and those of + +D. varicus +DV + +2 as rediae from gastropods in the White and Barents seas [ +30 +]. They were also identical to + +D. varicus + +of Olson +et al +. [ +50 +] (AY222189) ex + +H. platessoide + +s from the North Sea. On the other hand, they differed from the sequence of + +D. varicus + + +s. s +. + +from Norwegian + +S. salar + +by 3% as +p +-distance. This level of divergence is comparable to that observed between the well-established Mediterranean species + +D. ruber + +ex + +C. lastoviza + +from the Western Mediterranean, off +Algeria +(3% as well). Thus, the genetic divergence supports that + +D. abba + +n. sp. +is a separate species from + +D. varicus + + +s. s +. + +This species uses a different first intermediate host, and produces cercariae that can be morphologically distinguished from those of + +D. varicus + + +s. s +. + +[ +30 +]. + + + + +Krupenko +et al +. [ +30 +] speculated that + +D. varicus +DV + +2 is the species that Shulman and Shulman-Albova (1953) called + +D. crassus +Manter, 1934 + +. +Type +localities for + +D. crassus sensu +Manter (1934) + +and of + +D. abba + +n. sp. +are so distinct ( +Tortugas +, Florida, western Atlantic for + +D. crassus + +[ +42 +] +vs +. +Svalbard +, Arctic +Norway +, for + +D. abba + +n. sp. +) that we consider this unlikely. However, it remains possible that + +D. crassus sensu +Shulman and Shulman-Albova (1953) + +represents + +D. abba + +n. sp. + + + + +The lineage + +D. varicus +DV + +4 corresponds to an 18S rDNA sequence (AJ287511) of + +D. varicus + +of Littlewood and Olson [ +37 +] from the same host as + +D. abba + +n. sp. +, + +H. platessoides + +from the North Sea. DV4 was labeled only based on the genetic divergence of 0.13% ( +p +-distance) from + +D. abba + +n. sp. +(DV2) in the 18S rDNA sequence [ +30 +]. In light of the available data, it is premature to consider + +D. varicus +DV + +4 as a distinct species from + +D. abba + +n. p. considering that our study does not include the 18S rDNA analysis. Hence, we cannot estimate the taxonomical position of DV4 further. Meanwhile, the possibility that + +D. varicus + +( +s.s.) +also occurs in + +H. platessoides + +is not ruled out. + + +Overall, the evolution of understanding of this genus is such that while most combinations of species can be distinguished on the basis of morphology, some are presently morphologically cryptic with respect to each other. On this basis, it remains critical that further study is based on both morphological and molecular data. A key area of uncertainty relates to patterns of host-specificity. Some species, e.g. + +D. varicus +s.s. + +, appear to be genuinely euryxenic, whereas several others apparently have highly restricted host ranges. The extent to which this is a genuine reflection of the true nature of these species is uncertain. Certainly, for clearly closely related species, it is not obvious why host-specificity patterns should differ so dramatically. + + + + \ No newline at end of file diff --git a/data/3A/34/87/3A3487B25535FFE2FC88F9F9FC5DFAEB.xml b/data/3A/34/87/3A3487B25535FFE2FC88F9F9FC5DFAEB.xml new file mode 100644 index 00000000000..b000262a23d --- /dev/null +++ b/data/3A/34/87/3A3487B25535FFE2FC88F9F9FC5DFAEB.xml @@ -0,0 +1,645 @@ + + + +Untangling the Derogenes varicus species complex in Scandinavian waters and the Arctic: description of Derogenes abba n. sp.
