Abstract: In this study, we aimed to determine the prevalence of Toxoplasma gondii antibodies and identify risk factors associated with this infection in sheep from the southern region of Bahia state. Between February and December 2010, 795 sheep from 31 farms located in nine municipalities were tested. We found seroprevalence of 30.2% (240/795), with titers of 64 (38.3%), 256 (34.2%), 1,024 (18.3%), and 4,096 (9.2%) by Indirect Fluorescent Antibody Test (IFAT). Seropositive sheep were detected in all farms sampled. Uni… Show more

“…These factors, combined with carelessness or lack of knowledge about hygiene of facilities and about disposal of carcasses and fetal-placental debris, can increase T. gondii transmission. As indicated by our results, other studies showed that contact with cats increases the risk of toxoplasmosis in sheep (ANDRADE et al, 2012;GUIMARÃES et al, 2013;MENDONÇA et al, 2013). Therefore, adoption of preventive measures to avoid contamination of the sheep's food and water by cat feces, and to restrict the access of carnivores to sheep carcasses and placental/fetal debris after lambing/abortion, can reduce the risks of T. gondii transmission to cats, humans and sheep, and can reduce reproductive disorders in the flock.…”

“…The presence of antibodies against T. gondii in 100% of the farms indicates the relevance of this parasite in the flocks studied, as described in other regions of Brazil (SAKATA et al, 2012;GUIMARÃES et al, 2013). Widely variable frequencies of T. gondii seropositive sheep were found (10 -70%) within each of the ten flocks studied (Figure 3), as reported in Paraná state (28.6 -84%) (ROMANELLI et al, 2007).…”

“…Serum samples were tested for IgG antibodies against T. gondii by an indirect immunofluorescence test (IFAT) using F-7634-conjugated antibodies (Sigma-Aldrich, St. Louis, MO, USA) considering a 1:64 cut-off value (Guimarães et al, 2013). Negative and positive (1 x 10 6 experimentally inoculated tachyzoites of the T. gondii RH strain in a 6-month-old sheep) control sera were used for all the slides.…”
