摘要: Sheep are important domestic animals in the Northeast region of Brazil due to their minimal rearing and maintenance costs, production both meat milk. In animals, Toxoplasma gondii infection results significant reproductive economic losses. The epidemiology toxoplasmosis sheep has been little studied; particularly Rio Grande do Norte State. Sera from 102 intended for consumption Lajes were subjected Toxoplasma-ELISA test detect anti-T. specific IgG confirming a past infection. Of total tested, 30 (29.41%) sera positive with an increasing number advancing age. We used avidity ELISA samples observed that 6 (20%) had low antibodies 24 (80%) high antibodies. Epidemiological studies required order identify sources these hosts as well impact on animal breeding risk transmission humans.
