Occurrence of Toxoplasma gondii DNA in sheep naturally infected and slaughtered in abattoirs in Pernambuco, Brazil

Abstract: Pesq. Vet. Bras. 34(4):329-331, abril 2014 329 RESUMO.-[Ocorrência de DNA de Toxoplasma gondii em ovelhas naturalmente infectadas e abatidas em matadouros de Pernambuco.] Objetivou-se estudar a ocorrência de anticorpos contra Toxoplasma gondii e detectar o DNA genômico do parasito em órgãos reprodutivos, fetos e anexos fetais de ovelhas em matadouros no estado de Pernambuco, Brasil. Foram coletadas amostras de soro sanguíneo, útero, trompas e ovários, além de fetos e placentas. Para a triagem utilizou-se … Show more

“…Anestrus, follicular cysts, and salpingitis/hydrosalpinx were detected in the chronic phase of infection. Although the results of the present study were not able to confirm the presence of T. gondii in the reproductive tract (using either PCR or histopathological tests), T. gondii DNA was detected by PCR in the uterus, ovaries and tubes of a naturally infected sheep (BEZERRA et al, 2014). Moreover, reproductive failure due to T. gondii was previously described by STAHL et al (1994) among chronically infected female mice (cessation of estrous and constant diestrus cytology after one month), associated with marked infertility and uterine atrophy two months after infection, as well as impaired folliculogenesis.…”

“…In Kerala, a total of 98 goats screened for the presence of toxoplasma antibodies, and 58 were found positive [ 39 ]. Among 13 seropositive goats, the uterus of one goat showed the presence of the parasite DNA by PCR in Brazil [ 40 ]. In the present study, all samples were negative for T. gondii by PCR.…”
