Abstract
Toxoplasma gondii is an apicomplexan protozoan parasite that has been associated with reproductive failure in small ruminants. Although T. gondii infections in ruminants and humans have been recorded in severalEgypt's governorates,but little is known about the risk factors associated with T. gondii infections. In this study, 350 sheep and 290 goat serumsamples from three governorates in Egypt were examined for presence of antibodies against T. gondii, and evaluate the associate risk factors for theinfection. The seroprevalence in sheep and goats was 24% and 38.28%, respectively. In sheep and goats, age, sex, the presence of cats, and hygienic conditions were identified as risk factors for T. gondii infection. In addition, the prevalence rates were significantly higher in older animals more than 2 years old, females, among animals contacted with cats, and animals living in bad hygienic condition. In conclusion, sheep and goats in the examined regions are commonly infected with T. gondii. The identification of risk variables defines the sort of actions to be implemented in order to decrease, and prevent T. gondii infection in small ruminant animals and, as a result, human infection.
