ABSTRACT
Estudaram-se achados de necropsia de 454 espécimens de Leontopithecus. Quatorze (3,1 por cento) apresentaram-se infectados por acantocéfalos intestinais identificados como Prosthenorchis elegans (Diesing, 1861). Não foram observadas diferenças na ocorrência do parasito quanto à espécie, origem - cativos ou selvagens - e sexo. Clinicamente os animais apresentaram-se com o pelame eriçado, apatia, inapetência, dores abdominais e diarréia. Em dois animais parasitados (14,2 por cento), observou-se perfuração da parede intestinal. As lesões encontradas caracterizaram-se por uma grave enterite ulcerativa. A ocorrência desses parasitos reforça a necessidade do estabelecimento de protocolos sanitários rígidos no manejo das espécies de primatas do neotrópico
This study assessed the autopsy findings of 454 Leontopithecus specimens, 14 of which (3.1 percent) were infected by intestinal Acanthocephala identified as Prosthenorchis elegans (Diesing, 1861). No difference in the occurrence of the parasite was observed regarding the species, origin (captive or wild) and sex of the lion tamarins. Clinically, the animals had spiked coat, apathy, inappetence, abdominal pain and diarrhea. Two of the parasitized animals (14.2 percent) had perforation of the intestinal wall. The lesions found were characterized as a severe ulcerative enteritis. The occurrence of such parasites highlights the need for establishing strict sanitary protocols for the management of the neotropical primate species

For the first time, it was identified a mite in a three-year-old male ostrich that had lost feathers and showed skin irritation. The animal belonged to a flock of 50 birds, located in Baixada Fluminense, in Rio de Janeiro State. After they were fixed in 70 percent alcohol, clarifyed in lactophenol and mounted in Canada balsam, the mites were identified in the laboratory. They belonged to the Pterolichidae family and Struthioperolichus sculpturatus species (Hirst). The ostrich was treated by ivermectin in dose of 200µg/kg of body weight, with recovery and disappearance of the clinical symptoms. The occurrence of mite infestation by the described species in ostrich should be monitored by professionals and farmers, as they cause fall of feathers and economic losses.

Leihsmaniasis is a protozoal disease transmitted by dipteran insects. The dog is an important domestic host of both visceral and cutaneous forms of the disease. These forms affects humans in many countries, and it is considered a serious risk for human health. This study reports clinical and laboratorial data from 18 dogs. Nine dogs were positive by indirect immunofluorescence technique and the other nine were negative. The dogs were clinically monitored for 30 days and laboratorial changes were assessed. Three blood samples were collected for hemogram and serum biochemistry at 0, 15, and 30 days. The clinical signs of positive dogs were compatible with the disease, including lymphadenopathy, cutaneous ulcers, hyperthermia, apathy, cachexia and ulcerated mucosa. Marked differences were observed in the blood cell counts and blood biochemistry between positive and negative dogs. In conclusion, blood and biochemistry analyses of positive dogs were not sufficient to diagnose the disease within the period studied. The serologic test associated with the clinical signs are important to confirm the diagnosis.

Registra-se a presença de um espécimen macho de Dioctophyma renale (Goeze, 1782), localizado no tecido subcutâneo da regiäo inguinal esquerda de um cäo, medindo 30 cm de comprimento por 0,4 cm de diâmetro. Este é o segundo caso de D. renale na regiäo inguinal de cäo registrado na literatura brasileira
