[Swine cryptosporidiosis related to production systems in the state of Rio de Janeiro].

The purpose of this study was to verify the prevalence of cryptosporidiosis in swine farms of familiar and technical production systems, located in the North and Northwest Regions of the State of Rio de Janeiro. A total of 103 fecal samples of different swines were collected, proceeding from 10 farms, of which five were familiar and five technical. For the diagnosis, the modified concentration by sedimentation technique with posterior staining by modified Ziehl-Neelsen was used.

[Importance of the handling in criptosporidiosis in sheep rearing].

With the objective to verify which are the risk factors in ovine cryptosporidiosis, 130 ovine fecal samples were collected in ten farms in Campos dos Goytacazes and Macaé and analyzed using the modified Ziehl-Neelsen technique. Hygiene, breeding system, clinic alteration, veterinary assistance and source of water which were furnished to the animals were analyzed by χ2 Test and Fisher Exact Test, with Yates correction (when it was necessary) and 95% of confidence interval. Oocysts were observed in 47% of the farms.
