Resumo
The aim of this survey was to verify the occurrence of anti-Leptospira spp. antibodies in captive animals in the Parque Zoobotânico Arruda Câmara, João Pessoa, Paraíba State, Northeastern Brazil. Blood samples were collected from 49 animals: 26 mammals of the species Sapajus libidinosus, Cebus flavius, Saimiri sciureu, Coendu sp., Pseudalopex vetulus, Leopardus pardalis, Leopardus tigrinus, Galactitis vitata, Eira barbara, Nasua nasua, Tayassu tajacu and Ratus norvegicus; 10 birds of the species Penelope jacucaca, Pavo cristatus, Anodorhynchus hyacinthinus, Ara chlorothpterus, Pionites leucogaster, Polyborus plancus, Geranoaetus melanoleucus and Urubitinga urubitinga; and 13 reptiles of the species Caiman latirostris, Paleosuchus trigonatus, Caiman crocodilus, Tupinabis merinae, Tupinambis teguixin, Boa constrictor, Corallus hortulanus, Python molurus, Bufocephala vanderhaegei, Geochelone denticulata and Geochelone carboraria. Sera were examined by the microscopic agglutination teste (MAT) using 24 serovars as antigens and cut-off point of 1:100. One ocelot (Leopardo pardalis) presented positive reaction for the Icterohaemorrhagiae serovar with titer of 100, however, it did not show any clinical sign of the infection. Sinantropic rodents are the main reservoirs of this serovar, which suggests the need of maintenance and continuous evaluation of rodent control programs.Canine brucellosis is an infectious disease of worldwide distribution that can affect dogs, wild canids and man. It is caused by Brucella canis, but dogs can also be infected by smooth Brucella such as B. abortus and B. suis. Due to the increasing importance of dogs in our society, to the scarcity of information about canine brucellosis in the country and its zoonotic character, the aims of the present study were (i) to conduct a survey on the infection by B. canis and smooth Brucella in dogs from the municipality of Araguaína, Tocantins, Brazil, and (ii) to evaluate the risk factors associated with these infections. Sera from 241 dogs were analyzed by agar gel immunodiffusion (AGID) to detect B. canisantibodies, and Buffered Acidified Plate Antigen test (BAPA) and fluorescence polarization assay (FPA) to detect antibodies to smooth Brucella. From the 241 tested dogs, 132 reacted in the AGID and 128 reacted in the BAPA, but only two were positive in FPA. The seroprevalences of B. canis and smooth Brucella infections in dogs in Araguaína were 54.77% (95% CI: 48.25 to 61.17%) and 0.83% (95% CI: 0.10 to 2.97%), respectively. The analysis of risk factors showed associations between B. canis infection and vaccination against leptospirosis, and between B. canis infection and use of manufactured food. In conclusion, data from the present study showed a low prevalence of infection by s
