Abstract:
Sets of small ribosomal DNA (SSU rDNA) and large ribosomal DNA (LSU rDNA) sequences were obtained for Philometroides moraveci Vismanis & Yunchis, 1994, Philometra kotlani (Molnár, 1969), Philometra rischta Skrjabin, 1923, Philometra cf. obturans (Prenant, 1886) (Philometridae), Sinoichthyonema amuri (Garkavi, 1972), Agrachanus scardinii (Molnár, 1966), Kalmanmolnaria intestinalis (Dogiel & Bychowsky, 1934) and Skrjabillanus tincae Shigin & Shigina, 1958 (Skrjabillanidae). Phylogenetic analysis of SSU rDNA data shows that dracunculoid nematodes are divided into two well-supported clades designated as Clade I and Clade II, respectively. Clade I includes the type species of the genus Philonema Kuitunen-Ekbaum, 1933, some species from the family Daniconematidae Moravec & Køie, 1987 and two subfamilies of skrjabillanids, Skrjabillaninae Shigin & Shigina, 1958 and Esocineminae Moravec, 2006. Clade II unites species from the families Dracunculidae Stiles, 1907, Micropleuridae Baylis & Daubney, 1926 and Philometridae Baylis & Daubney, 1926. Within the Philometridae, there are several well-supported groups of species, one of which unites freshwater Philometra spp. from the Palearctic cyprinids, identified as P. kotlani, P rischta, P. ovata (Zeder, 1803) and P. cyprinirutili (Creplin, 1825). However, the phylogenetic relationships of most philometrids are unresolved. An analysis of partial SSU and LSU rDNA sequences indicates that there is no direct phylogenetic relationship between Agrachanus Tikhomirova, 1971 (type species Skrjabillanus scardinii Molnár, 1966) and Skrjabillanus Shigin & Shigina, 1958 (type species Sk. tincae), which means that the genus Agrachanus can be resurrected. Our study confirms that Philonematinae Ivashkin, Sobolev & Khromova, 1971 should be elevated to the family rank. We formally establish the family Philonematidae Ivashkin, Sobolev & Khromova, 1971 stat. nov. We also suggest combining the superfamilies Dracunculoidea Stiles, 1907 and Camallanoidea Railliet & Henry, 1915 into the infraorder Camallanomorpha Roberts, Janovy & Nadler, 2013.

Abstract:
Coiled globose nematodes identified as Phlyctainophora squali Mudry and Dailey, 1969 (Nematoda; Dracunculoidea) were found associated with ulcer-like and cyst-like lesions on the external surface and in the buccal cavity of 19 of 63 Squalus acanthias, 1 of 21 Heterodontus francisci, 1 of 117 Rhinobatus productus, and 7 of 16 Prionace glauca from the California Bight (northeast Pacific). A single male worm was recovered from one of the cysts in S. acanthias and the present redescription of the species includes the first description of a male Phlyctainophora. Certain characters of the male (i.e., form of cephalic extremity, reduced caudal alae, reduced number of caudal papillae) agree with those of members of the Philometridae; other characters of the male (form of the oesophagus) and female (monodelphy) agree with those of the Guyanemidae. Phlyctainophora is treated as a Dracunculoidea incertae sedis.

Ichthyofilaria canadensis n.sp., from the eelpouts Lycodes lavalaei Vladykov and Tremblay, 1936 and Lycodes vahlii Reinhardt, 1838 from the northwest Atlantic off Newfoundland and Labrador, is distinguished from Ichthyofilaria dasycotti Yamaguti, 1935 by its smaller size, the presence of well-developed vulva and vagina, the more anterior extent of the anterior ovary and uterus, and the host and geographic distribution. The first-stage larva is microfilarioid and occurs in the blood of the host.

Abstract:
AbstractWe describe the larval developmental stages and life cycle of the dracunculid nematodeMexiconema cichlasomaein both the intermediate,Argulus yucatanus(Crustacea: Branchiura), and definitive hosts,Cichlasoma urophthalmus(Perciformes: Cichlidae), from the Celestun tropical coastal lagoon, Yucatan, Mexico. The morphological analyses showed significant differences between the total length of L1 found inM. cichlasomaegravid female and L2–L3 inA. yucatanus.This result indicates that theM. cichlasomaelarval development occurs in the intermediate host. We obtained sequences from the small subunit (SSU) ribosomal marker from larval stages ofM. cichlasomaeinA. yucatanusand adult nematodes inC. urophthalmus. Our morphological and molecular results support conspecificity betweenM. cichlasomaelarvae inA. yucatanusand the adult stages inC. urophthalmus. We briefly discuss the phylogenetic position ofM. cichlasomaeamong the Daniconematidae, and provide evidence of the monophyly of the daniconematids associated with branchiurid intermediate hosts. Based on the phylogenetic results, we support the transfer of theMexiconemagenus to the family Skrjabillanidae and do not support the lowering of family Daniconematidae to subfamily.

Abstract:
Le nematode a. Crassus, parasite de la vessie gazeuse de l'anguille japonaise, a recemment contamine l'anguille europeenne. Les modalites de son expansion rapide dans la plupart des cours d'eau europeens ont ete precisees. Les limites septentrionales de son expansion geographique ont ete definies. Diverses caracteristiques ayant trait a la morphologie (structure des teguments et importance des reserves de l'uf et du stade libre), au developpement (brievete du temps minimal de developpement chez l'hote intermediaire ainsi que de la periode prepatente), et a la biologie (duree de la survie de l'uf et du stade libre, temps de generation compris entre 30 et 45 jours) favorables a son expansion demographique ont ete mises en evidence. Une compatibilite elevee dans le compartiment hote intermediaire ainsi que l'utilisation massive et diversifiee de la paratenese lui assure une transmission efficace vers l'hote definitif. Les roles respectifs des hotes intermediaires et parateniques dans la transmission du parasite vers son hote definitif ont ete discutes. Des mecanismes regulateurs de type ii dans le compartiment hote intermediaire et de type iii chez les hotes parateniques et definitif (fecondite densite dependante ainsi qu'un faible succes des infestations secondaires) ont ete caracterises. Ces mecanismes contribuent a la stabilite du cycle. L'importance de cette parasitose justifie la mise en place d'un traitement. Les biodisponibilites immediate et orale du levamisole caracterisant son absorption, sa distribution et son elimination chez l'anguille europeenne sont compatibles avec son utilisation par voie orale en anguilliculture a des fins therapeutiques

Abstract:
Morphological characters are traditionally used in nematode systematics, however, morphological convergence and marginal differences between close relatives can obscure species diversity and confound taxonomic studies. This thesis applies molecular approaches to systematic problems in two groups of parasitic nematodes where morphological data is ambiguous. Ribosomal DNA (rDNA) variable regions such as the first and second internal transcribed spacers (ITS-1 and ITS-2), and the D3 expansion loop of the large subunit have consistently distinguished nematode species and provided a limited basis for phylogenetic inference between close relatives. I assess rDNA variation within Cystidicola spp. (Nematoda; Habronematoidea) and the superfamily Dracunculoidea to examine species diversity in both groups, and phylogenetic relationships in the Dracunculoidea. Phenotypic variation in Cystidicola spp. suggests unresolved variation within the genus. Distinct life histories, host ranges, reproductive strategies, and adult and egg morphologies define the two recognized Cystidicola spp. Variable host specificity and egg morphology in Cystidicola farionis is difficult to interpret and could reflect genetic species-level variation. I sequenced four rDNA regions (ITS-1, ITS-2, 5.8S, D3) from Cystidicola spp. isolates from a total of seven host species and nine locations in Ontario (ONT), British Columbia (BC) and Finland (FIN). The ITS-1, 5.8S, and D3 regions displayed no inter or intraspecific variation. Two ITS-2 types were identified which differed at four nucleotide positions: the ITS-2 from C. farionis (BC) and C. stigmatura was identical and 365bp long; the ITS-2 from ONT and FIN C. farionis was identical and 368bp long. No relationship between egg morphology and genetic variation was apparent. ITS-2 differences between morphologically distinct C. farionis (ONT and FIN) and C. stigmatura were expected but comparison of this region among C. farionis isolates produced a surprising result. The ITS-2 distinguishes C. farionis (BC) from C. farionis (ONT and FIN) and suggests a closer relationship between C. farionis (BC) and C. stigmatura. Morphological resemblance among close relatives and a lack of phylogenetically informative characters in the superfamily Dracunculoidea reiterates this need for more precise taxonomic markers. I examined the D3 and ITS-2 regions from a total of nine dracunculoid species to distinguish cryptic species (e.g. Philonema spp.), place unidentified nematodes within the current classification system, and infer phylogenetic relationships within dracunculoid families (e.g. the Philometridae and Guyanemidae). I sequenced the D3 of two dracunculoid species, Philometroides huronensis and an unidentified nematode from Eopsetta exilis, adding these to an existing D3 data set of seven dracunculoids and sequenced the ITS-2 from all nine species. These regions varied in their ability to distinguish close relatives. The D3 region distinguishes Philonema agubernaculum and P. oncorhynchi but not Cystidicola spp. whereas the ITS-2 is identical in the former taxa and distinct in the latter. Both ITS-2 and D3 data supported previous suggestions that the family Philometridae may be artificial, and that members of the Guyanemidae are affiliated with some philometrids (e.g. Philonema spp.).
