Abstract: |
A postmortem evaluation of a domestically bred, adult, female Xenopus laevis revealed the presence of a urinary bladder protozoanconsistent with Trichodina xenopodus. T. xenopodus is considered an incidental finding, as its presence in the urinary bladderin frogs has not been correlated with disease or with urinary bladder epithelial lesions. Trichodina spp. are ciliated protozoa knownto colonize many species of amphibians and fish. These protozoa frequently inhabit the skin and gills, but may also be present inthe urinary bladder of infected animals. Their presence on the skin and gills in low numbers is not related to disease; however,large numbers may indicate poor water quality and overcrowding.
