Occurrence of anti-Toxoplasma gondii antibody and evaluation of risk infection factors in goats raised in Sergipe state, Brazil

Abstract

ABSTRACT: The objective was to determine, through indirect immunofluorescence reaction (RIFI, 1:64), the occurrence of IgG antibodies to Toxoplasma gondii and the risk factors associated with infection in goats in the state of Sergipe. To this study were used 675 samples of blood of animals from 41 farms of the three state mesoregions from 2013 to 2014. The occurrence of seropositive goats was 30.07%, with 90.24% of farms with seropositive animals. The distribution of titers obtained was 37.93%, 11.82%, 17.24%, 18.22%, and 17.77% for 64, 128, 512 and 1024 respectively. The risk factors observed were farms that did not have facilities (p=0.000, OR=2.30, CI 95%=1.41-3.74), with flooded soils (p=0.011, OR=2.94, CI 95%=1.27-6.79), which provided feed on the ground (p=0.032, OR=1.69, CI 95%=1.04-2.74), in uncovered cages (p=0.032, OR=1.69, CI 95%=1.04-2.74), pasture-based feed (p=0.003, OR=3.52, CI 95%=1.53-8.09), with access from cats to (p=0.031, OR=1.45, CI 95%=1.03-2.04) and introduced new breeders in the last five years (p=0.036, OR=1.58, CI 95%=1.02-2.74).
