Brucelosis is an emergent disease and its complexity because the large number of bacterial involved species and also each one shows different epidemiological aspects associated to the pathogenesis in each host species. Aujezsky Disease has also a big potential to become an emergent disease as a consequence to the large host range and the ability to the viruses from Herpesviridae family jump to another species. The aim of this study was determine the Brucella abortus and Pseudorabies virus (PrV) prevalence in neotropical captive wild carnivores from three Zoos in the northeast of Brazil. Blood samples were collected from 42 animals, including 17 coatis (Nasua nasua), eight crabeating raccoons (Procyon cancrivorus), three crab-eating foxes (Cerdocyon thous), three hoary foxes (Lycalopex vetulus), two little spotted cats (Leopardus tigrinus), five tayras (Eira barbara), two greater grisons (Galictis vittata) and two neotropical river otters (Lontra longicaudis). To detect B. abortus antibodies, two different serological tests were performed; the Rose-Bengal test (RBT) and the Complement Fixation Test (CFT) and to detect PrV antibodies the virusneutralization was performed. Antibodies to PrV were not detected. Our results showed 19 (45.34%) negative and 23 (54.76%) positive in BBAT test. On CFT 8 (19.50%) were positive and 15 (80.50%). To determine the Pseudorabies epidemiological situation more studies should be necessary in another keep-in-captivity and also in free-range animal populations to well conclude that this virus is not present in these neotropical wild carnivores populations. We are far to incriminate any of these species as wild reservoir and as interfering with national control programs. However, the lack of knowledge of epidemiological aspects in wild populations certainly is an obstruction to evaluate the Brucellosis control program in this country.
