          Abstract

          Com o objetivo de comparar variáveis epidemiológicas na toxoplasmose em ovinos e caprinos, amostras de soro de animais de propriedades localizadas em duas regiões do Estado de Pernambuco, Brasil, foram testadas pela reação de imunofluorescência indireta (RIFI) para detecção de anticorpos anti-Toxoplasma gondii. Dos 173 soros ovinos testados, em 35,3% foram encontrados resultados positivos, enquanto 40,4% dos 213 soros caprinos foram positivos à RIFI. Em ovinos, associações significativas foram encontradas para sexo e raça, mas não para região, tipo de manejo ou falha reprodutiva. Os resultados da RIFI para os caprinos foram significativamente associados ao sexo, raça, região, tipo de manejo e de exploração, mas não com a ocorrência de falhas reprodutivas.

          In order to compare some epidemiological variables in goat and sheep toxoplasmosis, serum samples of animals from different farms in two regions from the State of Pernambuco, Brazil, were tested by indirect fluorescent antibody test (IFAT). Of 173 sheep sera tested, 35.3% had positive results, while 40.4% of 213 goats serum samples were positive to IFAT. In sheep, significant associations were found to sex and breed, but not to region, kind of management or reproductive failure. Results of IFAT for goats were associated to sex, breed, region, kind of management and exploration, but not to reproductive failure.

            Serological survey of antibodies to Toxoplasma gondii in goats, sheep, cattle and water buffaloes in Bahia State, Brazil.

            Serum samples from 439 goats, 240 sheep, 194 cattle and 104 water buffaloes were tested for antibodies to Toxoplasma gondii by a latex agglutination test. Antibodies to T. gondii were found in 28.93% of goats, 18.75% of sheep, 1.03% of cattle and 3.85% of water buffaloes, at a dilution of 1:64. The highest titres observed in goats, sheep, cattle and water buffaloes were 1:2048, 1:2048, 1:64 and 1:512, respectively.

              The incidence and economic significance of ovine toxoplasmosis in Uruguay.

              Antibodies to Toxoplasma gondii were measured before and after pregnancy in a 1:64 dilution of sera with the direct agglutination test in 1613 ewes from 18 farms in 8 different counties of Uruguay from 1992 to 1994. The overall seroprevalence increased from 28.7% before mating to 38.5% after lambing in 2.5 yr and thus, the incidence was 9.8%. Losses due to toxoplasmosis during pregnancy were estimated to be 1.4 to 3.9% of the total number of ewes investigated, amounting to approximately US$1.4-4.7 million for the whole country.
