Molecular Confirmation of Cysticercosis in a Captive Ring-Tailed Lemur () in Poland.

(1) Background: is a cosmopolitan tapeworm endemic to the northern hemisphere with an indirect lifecycle. Its definitive hosts are carnivores, and its intermediate hosts are rodents and rabbits. Nonhuman primates in zoos appear to be highly susceptible to cysticercosis.

Streptococcal endocarditis in a captive southern white rhinoceros (Ceratotherium simum simum).

Postmortem examination of a 43-yr-old male southern white rhinoceros (Ceratotherium simum simum) revealed gross lesions and histopathologic findings consistent with endocarditis. The animal was born in Umfolozi National Park, South Africa, and then it was moved at 2 yr of age to two successive European zoologic collections. For several weeks prior to death, the animal was increasingly recumbent or assuming a dog-sitting position.
