Epidemiological Aspects in the Leptospira spp. and Toxoplasma gondii Infection in Horses from Botucatu, São Paulo, Brazil

Leptospirosis and toxoplasmosis are zoonoses with high importance because of the economic and public health impact. This study was aimed to determine the seroprevafence of leptospirosis and toxoplamosis in 714 serum samples of horses from different farms from Botucatu, São Paulo, Brazil. The samples were researched for Toxoplasma gondii antibodies by indirect immunofluorescence antibody test (IFAT) and for Leptospira spp. antibodies by microscopic agglutination test. of 714 serum samples, 128 (17.9%; 95% Cl: 15.3%-20.9%) were positive for one or more serovars of Leptospira spp., with icterohaemorrhagiae, canicola, and castellonis as the most prevalent serovars, whereas 42 (5.9%; 95% CI: 4.4%-7.9%) were positive for T gondii, of which 33 samples (78.57%; 95% CI: 64.0%-88.2%) presented a titer of 16, 7 (16.7%; 95% CI: 8.4%-30.7%) a titer of 64, and 1 (2.38%; 95% CI: 0.6%-12.3%) a titer of 256. No significant difference was found among the results obtained and the associated variables such as age and sex. (C) 2012 Elsevier B.V. All rights reserved.

Avaliação sorológica de Parainfluenzavirus Tipo 1, Salmonella spp., Mycoplasma spp. e Toxoplasma gondii em aves silvestres

Newcastle disease, salmonellosis and mycoplamosis are the most important infectious diseases in poultry. Toxoplamosis is a common disease in urban environment. The present study investigated serologic evidence of these diseases in captive and wildlife birds, with rapid plate agglutination test, haemagglutination inhibition test, and modified agglutination test. In a total of 117 blood serum samples, 20 showed the presence of Toxoplasma gondii, Mycoplasma gallisepticum, and Salmonella spp. antibodies. Amazona aestiva was the specie with the highest number of positive individuals (13/20). We also verified the first detection of T. gondii antibodies in birds of prey from Mivalgo chimachima and Rupornis magnirostris species.
