ABSTRACT

Objetivou-se avaliar a frequência da infecção por Toxoplasma gondii em suínos abatidos para o consumo humano em dois matadouros na Região Metropolitana do Recife, Pernambuco com inspeção Sanitária Estadual. A pesquisa de anticorpos foi realizada por meio da reação de Imunofluorescência indireta, adotando-se o ponto de corte 1:64. Foram analisados 327 animais provenientes de seis cidades, Abreu e Lima, Igarassu e Paulista, Carpina, Paudalho e Tracunhaém. Observou-se frequência de 9,78% de soros positivos, com diluições iguais ou superiores a 1: 64. Os resultados obtidos alertam sobre os riscos de infecção por T. gondii pela ingestão da carne suína crua ou mal cozida, pois é provável que os suínos soropositivos abriguem cistos teciduais, ressaltando a importância de um manejo de criação adequado, visando a diminuição do risco de infecção nesta espécie.


The objective of the present study was to evaluate the incidence of Toxoplasma gondii infection in pigs slaughtered for human consumption in two slaughterhouses with sanitary inspection in the Recife metropolitan area, Pernambuco State, Brazil. Antibody testing was performed by the indirect fluorescent antibody test, adopting the cut-off 1:64. A total of 327 animals were analyzed from six cities: Abreu e Lima, Paulista, Igarassu, Carpina, Paudalho and Tracunhaém. A frequency of 9.78% positive sera was observed for dilutions equal to or greater than 1:64. These data suggest risks of infection with Toxoplasma gondii by ingestion of raw or undercooked pork, since it is likely that seropositive pigs could contain tissue cysts, emphasizing the importance of creating a suitable management, aimed at reducing the risk of infection in this species.

ABSTRACT

ABSTRACT IGG ANTIBODIES TO TOXOPLASMA GONDII IN PIGS FROM SLAUGHTERHOUSES OF THE RECIFE METROPOLITAN AREA, PERNAMBUCO STATE, NORTHEAST BRAZIL. The objective of the present study was to evaluate the incidence of Toxoplasma gondii infection in pigs slaughtered for human consumption in two slaughterhouses with sanitary inspection in the Recife metropolitan area, Pernambuco State, Brazil. Antibody testing was performed by the indirect fluorescent antibody test, adopting the cut-off 1:64. A total of 327 animals were analyzed from six cities: Abreu e Lima, Paulista, Igarassu, Carpina, Paudalho and Tracunhaém. A frequency of 9.78% positive sera was observed for dilutions equal to or greater than 1:64. These data suggest risks of infection with Toxoplasma gondii by ingestion of raw or undercooked pork, since it is likely that seropositive pigs could contain tissue cysts, emphasizing the importance of creating a suitable management, aimed at reducing the risk of infection in this species.

ABSTRACT

The aim of this study was to identify risk factors associated with Neospora caninum seropositivity in sheep from the State of Alagoas, in the northeast region of Brazil. Twenty-six herds were selected, and blood samples were collected from 343 animals > 6-mo-old. The indirect fluorescent antibody test (IFAT) was used for serological diagnosis of N. caninum infection. Epidemiological questionnaires were applied for each herd to identify the risk factors associated with infection. Thirty-three (9.6%) animals tested positive for anti- N. caninum IgG antibodies, with titers ranging from 1 ratio 50 to 1 ratio 1,600. Fourteen herds (53.8%) presented at least 1 seropositive animal. Risk factors identified were property size
