Abstract
This study aimed to estimate the occurrence of anti-Toxoplasma gondii antibodies by means of the Indirect Immunufluorescent Antibody Assay (IFAT) in cattle and pigs from slaughterhouses in two municipalities in the State of Rio de Janeiro. IgG anti-T. gondii antibodies was found in 1.96% (9/459) of the cattle and 7.64% (31/406) of the pigs, without any positive association (p > 0.05) with risk factors for transmission and seropositivity. Taking the cutoff point of IFAT ³ 1:64, titers of 64 and 256 were detected, suggesting chronic infection. Despite the low prevalence rates found for cattle and pigs, these indicated environmental contamination in the municipalities investigated, biosafety failures at the technified pig farm evaluated and the possibility of human and animal infection through eating raw or undercooked meat from these animals.
Este trabalho objetivou estimar a ocorrência de anticorpos anti-Toxoplasma gondii por meio da Reação de Imunofluorescência Indireta (RIFI) em bovinos e suínos de abatedouros de dois municípios do Estado do Rio de Janeiro. Anticorpos IgG anti-T. gondii foram encontrados em 1,96% (9/459) dos bovinos e em 7,64% (31/406) dos suínos, sem associação positiva (p > 0,05) em relação aos fatores de risco de transmissão e a soropositividade. Considerando-se o ponto de corte (RIFI ³ 1:64), foram detectados os títulos de 64 e 256, sugestivos de infecção crônica. Apesar de baixas, as prevalências encontradas para bovinos e suínos indicaram contaminação ambiental nos municípios avaliados, falhas na biossegurança da granja tecnificada de suínos e a possibilidade de infecção humana e animal pela ingestão da carne crua ou mal passada desses animais.
