epidermal capillariasis in south african clawed frogs (xenopus laevis).significant morbidity and mortality of south african clawed frogs, xenopus laevis, can be caused by parasitism of the epidermis by a capillarid nematode. these worms produce an erosive dermatitis that is complicated by infection with gram-negative microorganisms. the nematode apparently has a direct life cycle that can be completed within the epidermis of the frog. these characteristics are suggested by the lack of an intermediate host and failure to detect visceral migration. another unique fea ...19873613514
wasting disease associated with cutaneous and renal nematodes, in commercially obtained xenopus laevis.xenopus laevis, the south african clawed frog or toad, is a member of the family pipidae. now in high demand for research purposes, they are available commercially. its reported lifespan is up to fifteen years. investigators and caretakers are frustrated when commercially obtained, young frogs (four years or younger), not subjected to any studies, "waste" and die. the wasting syndrome is characterized by anorexia, color change, and "flaky skin." often the first sign of this syndrome is the prese ...19921626871
anthelmintic treatment to eradicate cutaneous capillariasis in a colony of south african clawed frogs (xenopus laevis).the nematode capillaria xenopodis (pseudocapillaroides xenopi), a skin parasite of south african clawed frogs (xenopus laevis), is quite common in laboratory animal facilities. it causes serious skin changes and may further lead to wasting and death of affected frogs. various treatment protocols, using the anthelmintics ivermectin and levamisole, were successively tested for practicability of elimination of the parasite from a colony of clawed frogs. nematodes were reduced below diagnostic level ...19979355089
molecular phylogeny of pseudocapillaroides xenopi (moravec et cosgrov 1982) and development of a quantitative pcr assay for its detection in aquarium sediment.we used high-fidelity pcr to amplify a portion of the small ribosomal subunit (18s rrna) of pseudocapillaroides xenopi, a nematode that parasitizes the skin of xenopus laevis. the 1113-bp amplicon was cloned, sequenced, and aligned with sequences from 22 other nematodes in the order trichocephalida; caenorhabditis elegans was used as the outgroup. maximum-likelihood and bayesian inference phylogenetic analyses clustered p. xenopi in a clade containing only members of the genus capillaria. our an ...025650974
