RESUMO
Avaliou-se a circulação de Campylobacter spp. em uma criação de primatas neotropicais macacos-de-cheiro (Saimiri spp.), clinicamente saudáveis, utilizados em investigações biomédicas. A análise foi feita no decorrer de sete anos não consecutivos, de 1995 a 1999, 2002 e 2003. Os resultados revelaram um maior índice de positividade no ano de 1996, em contraste com a ausência do agente em 2003. Os dados sugerem que as alterações realizadas no manejo animal, ao longo deste estudo, foram eficazes para a eliminação do Campylobacter spp. na criação de macacos-de-cheiro, levando os animais a uma melhor qualidade de vida e, consequentemente, obtendo-se um melhor produto para fins de pesquisas.
The circulation of Campylobacter spp. in a breeding colony of clinically healthy neotropical primates squirrel monkeys (Saimiri spp.) used in biomedical investigation was evaluated. Analyses were undertaken during seven non-consecutive years: 1995 to 1999, 2002 and 2003. Results revealed a higher rate of positivity in 1996, in contrast to the absence of the agent in 2003. The data suggest that the changes made in the animal management during this study were effective for the Campylobacter spp. elimination of the squirrel monkeys breeding colony, leading to a better quality of life and, hence, resulting in a better animal for research.
RESUMO
BACKGROUND: Agnathia is a rare malformation characterized by the absence of the mandible. METHODS: A male rhesus monkey with malformations was found dead and studied by internal examination, radiographs and histopathology. RESULTS: A case of a rare first branchial arch anomaly with agenesis of the mandible and tongue is presented. The animal also had visceral deformities. However, ears were normal in shape and only slightly low in position. The craniofacial malformations may reflect incomplete separation of the first branchial arch into its maxillary and mandibular processes. CONCLUSIONS: The association between the craniofacial and other corporal anomalies is unclear.

The immunogenicity and protective efficacy of various antigen-adjuvant formulations derived either from the merozoite-surface protein-3 (MSP-3) or the glutamate-rich protein (GLURP) of Plasmodium falciparum were evaluated in Saimiri sciureus monkeys. These proteins were selected for immunogenicity studies based primarily on their capacity of inducing an antibody-dependent cellular inhibition effect on parasite growth. Some of the S. sciureus monkeys immunized with MSP-3(212-380)-AS02 or GLURP(27-500)-alum were able to fully or partially control parasitaemia upon an experimental P. falciparum [Falciparum Uganda Palo Alto (FUP-SP) strain] blood-stage infection, and this protection was related to the prechallenge antibody titres induced. The data are indicative that MSP-3 and GLURP can induce protective immunity against an experimental P. falciparum infection using adjuvants that are acceptable for human use and this should trigger further studies with those new antigens.
