A Survey of Diseases in Passeriform Birds Obtained From Illegal Wildlife Trade in Sao Paulo City, Brazil

The order Passeriformes comprises the largest number of families and species of birds of any avian order. Brazil is rich in passerine birds, which are a common victim of wildlife trafficking in Brazil. Annually, many birds die as a consequence of illegal trade. To investigate the occurrence of the principle diseases and to identify the main causes of death in smuggled passerine birds, the cause of death was evaluated in 360 passerine birds confiscated within the city of Sao Paulo, Brazil. Causes of death were determined by anatomopathologic and microbiologic studies. Infectious diseases were the cause of death of most birds, which corresponded to 78.6% of cases. The most common infectious diseases were poxvirus infection, aspergillosis, and coccidiosis. Although the etiologic agents of these diseases can coexist asymptomatically within hosts, once the host`s immunity is compromised, the pathogen multiplies quickly and causes disease. The results of this study may help to improve the care of passerine birds in captivity and increase the survival rate of confiscated birds. Results may also be useful for in situ conservation programs that investigate the reintroduction of confiscated species or captive birds.

Serological survey of Toxoplasma gondu in captive Neotropical felids from Southern Brazil

Toxoplasma gondu is the causative intracellular protozoan of toxoplasmosis inhuman being and animals Members of the Felidae family are considered the single definitive host for the infection both wild and domestic cats are able to excrete oocysts in the environment Wild cats maintained in captivity may serve as source of infection for other clinically susceptible animals in the same environment The aim of this study was to determine the frequency of T gondu IgG antibodies in 57 neotropical felids (1 Leopardus geoffroyi 3 Puma yagouaroundi 17 Leopard us wiedu 22 Leopardus tigrinus and 14 Leopard us pardalis) kept at the Bela Vista Biological Sanctuary Itaipu Binacional Southern Brazil by the modified agglutination test (MAT) using titer 16 as cut-off point Seropositivity was observed in 38/57 (66 67% 95% CI 53 66-77 51%) samples with higher frequency in ocelots (71 43%) Wild-caught felids were three times more likely to be infected when compared to zoo-born animals (P <= 0 05) and age of wild-caught animals (P= 0 6892 95% CI = 0 7528-166) was not significant as a risk factor for the infection the same occurring with zoo-born animals (P=0 05 95% CI = 06267-24052) These results suggest that despite efforts to control T gondu infection in zoo facilities such as individual pens hygiene monitoring veterinary care and pre-frozen meat offered as food non-domestic feuds kept in captivity particularly the wild-caught specimens may be invariably exposed to infection due to other environmental sources (C) 2010 Elsevier B V All rights reserved

SEROLOGIC SURVEY FOR SELECTED INFECTIOUS DISEASES IN FREE-RANGING BRAZILIAN TAPIRS (TAPIRUS TERRESTRIS) IN THE CERRADO OF CENTRAL BRAZIL

From September 2000 to January 2002, a serologic survey was conducted in a population of free-ranging Brazilian tapirs (Tapirus terrestris) inhabiting Emas National Park and surrounding areas in Goias state. central Brazil, as part of an ecologic study. Ten tapirs were immobilized with a tiletamine-zolazepam combination. and blood samples were collected. All sera were negative for Leptospira spp.. Brucella abortus, and equine infectious anemia; and one of 10 animals was positive for Toxoplasma goudii. This report represents the first serologic survey for selected infectious diseases in a free-ranging population or Brazilians tapirs in central Brazil.
