The present study reports the occurrence of helminths in the introduced species Tupinambis merianae (tegu lizard), and in two endemic species Trachylepis atlantica (small lizard) and Amphisbaena ridleyi (two-head-snake lizard ), from Fernando de Noronha Archipelago, State of Pernambuco, Brazil. Nine species of helminths were found, mainly in the digestive tract and accessory organs, with the following prevalence (P) and mean infection intensity (MII). Tupinambis merianae: Diaphanocephalus galeatus (P = 96%, MII = 20.5), Spinicauda spinicauda (P = 100%, MII = 197.8), and Oochoristica sp.l (P = 20%, MII = 4.4). Trachylepis atlantica: Moaciria alvarengai (P = 20%, MII = 1.4), S. spinicauda (P = 92%, MII = 22.1), Mesocoelium monas (P = 4%, MII = 3.0), Platynosomum sp. (P = 8%, MII = 7.0), and Oochoristica sp.2 (P = 16%, MII = 1.25). Amphisbaena ridleyi: Aplectana albae (P = 96%, MII = 143.4), Thelandros alvarengai (P = 4%, MII = 1.0), Me. monas (P = 44%, MII = 2.8), Platynosomum sp. (P = 36%; MII = 13.8), and Oochoristica sp.2 (P = 48%; MII = 2.17). More than 80% of T. merianae were infected with 2, or more, helminth species. In Tr. atlantica, single-species infections were present in 50% of the specimens, but co-occurrence of 2 parasites was also high (41.7%). In A. ridleyi, multiple infections were more common, with up to 5 parasite species present. The helminth fauna observed allowed us to conclude that helminths can be carried together with their host when they colonize new geographic localities and that these introduced helminths can, in turn, colonize endemic, or native, hosts.
RESUMO.-Sapajus flavius e S. libidinosus são duas espécies de macacos-prego encontrados no Estado da Paraíba. S. flavius ou macaco-prego-galego foi recentemente redescoberto e está criticamente ameaçado de extinção, sendo encontrado em fragmentos remanescentes de mata Atlântica do litoral do RN, PB, PE e AL. S. libidinosus tem uma distribuição e população maior, coexistindo de S. flavius na PB, entretanto, ocupando o oeste da PB, na caatinga. Frente à lacuna no conhecimento sobre estas espécies foi realizada a descrição morfológica das mesmas, envolvendo biometria externa, dos órgãos do trato gastrointestinal, topografia visceral e a descrição anatômica. Apesar da literatura descrever S. flavius como o menor dos Sapajus, concluímos que não há diferenças morfológicas entre as espécies estudadas. Tais informações servem de subsídios para melhores manejos visando a conservação das espécies e ajudando na classificação taxonômica desse gênero recentemente modificado. INTRODUÇÃOO macaco-prego-dourado ou macaco-prego-galego (Sapajus flavius) é uma espécie de macaco-prego que há muito se acreditava estar extinta, sendo redescoberta recentemente (Pontes et al. 2006 rromaoguerra@gmail.com Sapajus flavius and S. libidinosus are two species of capuchin monkeys found in the state of Paraíba, Brazil. S. flavius or Macgrave´s capuchin monkey was recently rediscovered and is now critically endangered, found only in remaining fragments of Atlantic forest in the coastal region of the Brazian Northeast. S. libidinosus has a larger population and distribution, coexisting with S. flavius in Paraíba, however living in the western part of the state, in the semi-arid. Since there is a lack of knowledge about these species, a morphologic description of them was made, involving external and gastrointestinal tract biometry, visceral topography and anatomic description. Although the literature describes S. flavius as the smaller monkey of the Sapajus genus, we conclude that there are no morphological differences between these species. Such information contributes to best management practices for conservation of the species and to the correct taxonomic classification of the genus recently modified.
Submetido em 13/11/2014 Aceito para publicação em 15/05/2015 Resumo O objetivo deste estudo foi isolar e identiicar enterobactérias presentes em duas populações de macacosprego-galego (Sapajus lavius) mantidas em cativeiro. O estudo foi realizado com 12 animais, seis do Centro de Triagem de Animais Silvestres (CETAS), em Cabedelo-PB, e seis do Zoológico de João Pessoa. A coleta das amostras de fezes foi realizada diretamente na ampola retal com o auxílio de swabs estéreis e processadas para o isolamento das bactérias em meios seletivos, seguida da identiicação por provas bioquímicas. As frequências observadas nas amostras do CETAS foram de: 80% (4/5) para Salmonella spp.; 20% (1/5) para Shigella spp.; e 20% (1/5) para Enterobacter spp. Já no zoológico, a frequência observada foi de 100% (3/3) para Salmonella spp. Devido ao fato de que essas enterobactérias são possíveis causadoras de infeções, há necessidade de melhorar o monitoramento da saúde desses animais, com investigações periódicas em unidades do CETAS e em zoológicos. Simultaneamente, constata-se a necessidade de monitorar a saúde dos proissionais que lidam diretamente com esses animais, por meio de exames periódicos, bem como a adoção de medidas de biossegurança adequadas para evitar a transmissão desses patógenos.
The present study aimed to evaluate the microbiological and physicochemical quality of curd cheese commercialized in Alagoas (BRAZIL). Thirty samples were collect during a five months period in six points of sale. It was estimated the number of coagulase-positive Staphylococcus and coliforms, as well as the presence of Salmonella spp. and Listeria monocytogenes. Regarding physicochemical characteristics, pH, fat content and humidity were evaluated. Among the thirty analyzed samples, 20 (66.6%) were in accordance with Brazilian legislation parameters for coliforms, while 10 (33.3%) surpassed those limits. For coagulase-positive Staphylococcus 15 samples (50%) showed values above the allowed by legislation. None of the samples analyzed harbored Salmonella spp. or Listeria monocytogenes. Regarding physicochemical parameters, the average values observed were of 5.89 for pH, 23.6% for fat content and 46.96 g/100 g for humidity. Overall, the results obtained reflect the poor hygienic conditions observed from manufacture to commercialization, pointing towards a potential health risk for curd cheese consumers. Furthermore is necessary to regulate physicochemical standards for curd cheese fabication.
