The aim of the present study was to evaluate the frequency of rhabdiasid nematodes in recently captured Crotalus durissus terrificus snakes from São Paulo State, Brazil. Fifty snakes (34 males and 16 females) were studied and each one was evaluated for the presence of that nematode at the moment of receipt at the Institution and after 90 days of quarantine inside individual cages. Tracheopulmonary washeswere examined. Snakes that died during quarantine underwent necropsy and lung examination. Analysis of the results obtained at the two evaluation times (0 and 90 days), in addition to the data obtained during necropsies, showed that 44% (18 males and 4 females) of the C. d. terrificus snakes were naturally infected by rhabdiasid nematodes. These data demonstrate the parasitism level in natural conditions and are important for the sanitary handling of these reptiles in captivity.

Haplometroides buccicola (Trematoda, Digenea, Plagiorchiidae) was reported in the mouth and oesophagus of Phalotris lativittatus (Serpentes, Colubridae) from Botucatu, São Paulo State, Brazil. This is the first report on the occurrence of H. buccicola parasitizing P. lativittatus. The Haplometroides genus was also discussed and the most important morphological characters for the identification of the species H. buccicola and H. odhneri are presented.

We describe a case of trichomoniasis in a Bothrops jararaca (Serpentes, Viperidae) donated to the Center for the Study of Venoms and Venomous Animals - CEVAP/UNESP. The animal had diarrhea with great quantity of flagellated protozoa in the feces. Microscopic examination of fecal smears stained with Giemsa revealed the presence of trichomonads, morphologically similar to Trichomonas acosta. Trichomonads were not detected in fecal exams after treatment with a single dose of 40 mg/kg metronidazole (Flagyl®).

The objective of this paper is to report the death of a Boa constrictor amarali after ingestion of a tree porcupine. The animal was donated to the Center for the Study of Venoms and Venomous Animals (CEVAP/UNESP) - and died in captivity. At necropsy, spine-like structures were observed in the stomach serosa and vicinity, and the stomach mucosa showed an intense reddish area, suggesting inflammation. The analysis of the spine-like structure revealed that they were tree porcupine spines. The feeding habits and inexperience of this Boa constrictor amarali in selecting its prey may have been be responsible for its death.

This study reports the isolation of an Ophidian Paramyxovirus (OPMV) in sputum of a captive rattlesnake (Crotalus durissus terrificus) kept in a serpentarium located in Botucatu, São Paulo State, Brazil. Polymerase chain reaction (PCR) and nested-PCR were performed for the identification of the isolated virus.
