ResumoForam analisados 600 soros de bovinos abatidos nos matadouros sob Inspeção Municipal de Ilhéus e Itabuna, e no matadouro frigorífico sob Inspeção Federal em Jequié, BA, para anticorpos anti-Toxoplasma gondii por imunofluorescência indireta. A prevalência total foi de 11,83% (71), sendo os animais positivos 19,3% (37) no matadouro de Ilhéus, 9,8% em Itabuna (21) e 6,8% (13) em Jequié. Dos animais positivos, 65 (91,5%) tiveram título de 1:64, e 6 (8,5%) de 1:256. A maioria dos soros positivos para T. gondii foram oriundos de animais provenientes de granjas leiteiras e foram abatidos nos matadouros sob inspeção municipal em comparação com aqueles animais que procederam de fazendas com criação extensiva, e abatidos em matadouros sob inspeção federal.Palavras-chave: Toxoplasmose, prevalência, gado de abate.
AbstractSerum samples of 600 slaughtered cattle from Ilhéus and Itabuna Municipal slaughterhouse and Jequié Federal slaughterhouse, all of them located in the State of Bahia were screened using an indirect immunofluorescent antibody test against Toxoplasma gondii. Prevalence was 11.83% (71), and positive samples were distributed as 19.3% (37) from Ilhéus, 9.8% (21) from Itabuna and 6.8% (13) from Jequié slaughterhouses respectively. From positive cattle, 91.5% (65) had titles 1:64, and 8.5% (6) had title 1:256. The majority of serum positive samples against T. gondii were related to animals from dairy farms which were slaughtered at municipality stockyards under municipal inspection in comparison with those slaughtered at Federal inspection which were related to beef cattle that were raised in farms extensively.
This study was performed to verify the occurrence of anti-Toxoplasma gondii antibodies in swine raised and slaughtered in the state of Bahia, Brazil. Four hundred sixty five swine blood samples from farms of different cities had been collected and examined. Anti-T. gondii antibodies was detected by the enzyme-linked immunosorbent assay (ELISA) and considered positive all the animals with equal or bigger headings than 1:16. From these, 18.27% (85/465) of total sample were positive for T. gondii, 30.76% (24) in Ilhéus, 18.10% (21/116) in Itabuna and 14.76% (40/271) in Simões Filho. Significant differences were observed regarding animal sex (p = 0.0171), raising system (p = 0.0002) and origin of the animals (p = 0.0278) in the city of Itabuna. The occurrence of anti-T. gondii antibodies shows that swine can be a source of infection for the local human population.
