Seroprevalence of toxoplasma gondii infection in pigs from southwestern mississippi

This study focused on the southwestern region of Mississippi. Between July 2003 and March 2004, blood samples were collected from slaughterhouses in southwestern Mississippi and the Alcorn State University swine farm in Churchill, Mississippi. The collected blood samples were centrifuged and the sera were collected, labeled, and stored in a freezer at -20 C. The modified agglutination test was performed at dilutions of 1:25, 1:50, and 1:500. A titer of 25 was considered seropositive. Of a total of 302 samples tested, 48 (16%) were positive at a titer of 25; 29 (10%) were positive at 50; 11 (4%) were positive at 500. The seroprevalence of T. gondii in pigs in southwestern Mississippi is not as high as previous studies done in Mississippi. This could be attributed to the sample size. However, the potential for infection still exists.PMID:38232759 | DOI:10.1645/23-79
