Resumo
Toxoplasmosis is a zoonosis of wide distribution worldwide, caused by the protozoan
Toxoplasma gondii, which can cause economic losses in sheep production mainly due to the
appearance of reproductive disorders. In addition, sheep infected with T. gondii may represent
a potential risk to human health, due to the large cystogenic capacity that some isolates of
the parasite present, leading to the possibility of human infection through the ingestion meat
from infected animals. In this sense, the objective of the aforementioned work was to
evaluate seroprevalence and risk factors for Toxoplasma gondii infection in sheep in the state
of Goiás, located Center-Western region of Brasil. For this purpose, through the indirect
immunofluorescence reaction (IFA), 1000 serological samples from sheep from the 18
microregions were analyzed. of State. The data were analyzed using Pearson's chi-square
test, which evaluated the possible risk factors for T. gondii (p≤0.05), with the odds ratio (OR)
estimates obtained, with a confidence interval of (CI) 95%. The risk factors were calculated
considering the risk for each animal, (calculated from the risk), using the software Statistica
10 (StartSot Inc., 2011). In 34.3% (343/1000) of the analyzed samples, the occurrence of
anti- T. gondii antibodies (IgG) was observed with serological titers ≥ 64 to ≥ 65536 that
varied in the regions from 18.1% (15/83) to 64.15% (34/53). In all regional unitis sampled in
the state of Goiás, seroreagent animals were detected, being the age, the water, the form of
replacement of the herd and the presence of domestic cats and wild animals, considering the
risk factors statistically associated with the serum-occurrence of antibodies against
Toxoplasma gondii in sheep.
