Nearctic Shrews, Sorex spp., as Paratenic Hosts of Soboliphyme baturini (Nematoda: Soboliphymidae)

Geographic and host range of the nematode Soboliphyme baturini across Beringia.

The nematode Soboliphyme baturini Petrov, 1930, was found to represent a single species with a relatively broad geographic range across Beringia and northwestern North America on the basis of the assessment of molecular sequence data for adult and juvenile parasites. Refuted are hypotheses suggesting that several cryptic species could be partitioned either among an array of mustelid definitive ...

The first record of amphibians as paratenic hosts of Serpinema larvae (Nematoda; Camallanidae).

Until now the third-stage larvae of Serpinema trispinosum (Leidy, 1852) was only found infecting aquatic snail and planktonophagous fish as paratenic hosts (Bartlett and Anderson, 1985; Moravec et al., 1998). The life cycle of this nematode is unknown. Apparently, the freshwater turtles may become infected by ingestion of zooplankton intermediate hosts (e.g., copepods) or by feeding on parateni...

Experimental studies on the development of Contracaecum rudolphii (Nematoda: Anisakidae) in copepod and fish paratenic hosts.

The larval development of the nematode Contracaecum rudolphii (Rudolphi, 1819), a common parasite of the proventriculus of cormorants, was experimentally studied. Within the eggs cultivated in freshwater under laboratory temperatures of 20-22 degrees C, the developing larva undergoes two moults on days 4-5, attaining the third larval stage. Most of the ensheathed third-stage larvae, 291-457 mic...

Amphibians and larvae of aquatic insects as new paratenic hosts of Anguillicola crassus (Nematoda: Dracunculoidea), a swimbladder parasite of eels.

Amphibians (tadpoles of the frog Bombina bombina [L.] and the newt Triturus vulgaris [L.]) and aquatic insects (larvae of the alderfly Sialis lutaria [L.] [Megaloptera], dragonflies Sympetrum sanguineum [Miller] and Coenagrion puella [L.] [Odonata], and the caddisfly Oligotrichia striati [L.] [Trichoptera]) were found to serve as paratenic hosts for the third-stage larvae (L3) of the nematode A...
