SEROSURVEY OF TOXOPLASMA GONDII IN SHEEP FOR HUMAN CONSUMPTION IN TWO SLAUGHTER-HOUSE

摘要

The purpose of this study was to put in evidence the presence of IgG antibodies type anti-T. gondii and the prevalence of infection in sheep slaughtered in two slaughterhouses in the north-western of Romania, for public consumption. It have been collected 105 sera in the direction of detecting antibodies (IgG) anti-T. gondii by ELISA method, using a commercial kit (Chekit Toxotest, Idexx-Bommeli, Switzerland). The sheep were divided into two groups according to age: group one - 2-3-year-old sheep (51); group two - 7-8-year-old sheep (54). Of the 105 sera sheep processed 48 were positive, achieving a prevalence of 45.7%. The prevalence of anti-T. gondii antibodies in sheep from group one was 45% (23/51), while in group two was 46.3% (25/54). The increased preavalence obtained by ELISA techniques, shows the presence of antibodies anti-T. gondii at 45.7% of examined sera, and there is a real risk of human contamination following row meat consumption.
