sero-prevalence of toxoplasma gondii in cattle from assam

Prevalence of Toxoplasma gondii infection among cattle of Assam was determined serologically by Modified agglutination test (MAT) and Latex agglutination test (LAT). MAT showed 26.66% seroprevalence against 16.66% recorded by LAT in sera of open grazing cattle. Antibody titres in positive sera ranged from 1:25 to 1:3200 in MAT while in LAT the highest titre recorded was 1:256. Sera from farm borne stall-fed cattle were all negative in both the tests suggesting lack of their exposure to infective cat faeces.
