AI Article Synopsis
- The survey aimed to assess the prevalence of anti-Toxoplasma gondii antibodies in sheep across 63 flocks in Paraíba, Brazil, and identify related risk factors.
- A total of 540 blood samples were analyzed, revealing that 28 out of 63 flocks (44.44%) and 60 out of 540 sheep (11.11%) tested positive for T. gondii antibodies using an indirect immunofluorescent antibody test (IFAT).
- A notable risk factor identified was flock size, specifically flocks with more than 25 animals, which had a higher likelihood of seropositivity (odds ratio = 3.2).
Article Abstract
The aims of this survey were to determine the flock-level and animal-level prevalences of anti-Toxoplasma gondii antibodies in sheep in the State of Paraíba, Northeastern Brazil, and to identify risk factors. Blood samples were collected from 540 sheep in 63 flocks in 14 municipalities in the Sertão mesoregion. To serologically diagnose T. gondiii nfection, the indirect immunofluorescent antibody test (IFAT) was used. Flocks with at least one seropositive animal were considered positive. Among the 63 flocks, 28 (44.44%) were positive, and 60 (11.11%) of the 540 animals were seropositive. Variable flock size > 25 animals was identified as a risk factor (odds ratio = 3.2; 95% CI = 1.09 - 9.34; P = 0.033). The results from this survey demonstrate that T. gondii is spread among sheep in the State of Paraíba.
