high prevalence and abundant atypical genotypes of toxoplasma gondii isolated from lambs destined for human consumption in the usa.little information is available on the presence of viable toxoplasma gondii in tissues of lambs worldwide. the prevalence of t. gondii was determined in 383 lambs (<1 year old) from maryland, virginia and west virginia, usa. hearts of 383 lambs were obtained from a slaughter house on the day of killing. blood removed from each heart was tested for antibodies to t. gondii by using the modified agglutination test (mat). sera were first screened using 1:25, 1:50, 1: 100 and 1:200 dilutions, and hea ...200818191859
