Toxoplasmosis, caused by Toxoplasma gondii, is a significant disease in livestock and humans. In Iran, studies shows that T. gondii infection in humans is relatively high and prevalence is associated mainly with consumption of undercooked meat or meat products. We have examined 450 serum samples from female cattle distributed over all Ahvaz, the center of Khouzestan province, south-west of Iran. IgG antibodies to T. gondii were assayed by the modified agglutination test using whole tachyzoites of T. gondii, and found in 71 (15.77%) of 450 cattle with titers of 1:25 in 38, 1:50 in 18, 1:100 in 11, 1:200 in three and 1:400 in one. Titers of antibodies were decreased in cattle over 2 years old. These results indicate that T. gondii infection in cattle of Khouzestan is relatively considerable, but not very high and consumption of beef may be a source of infection for humans in south-west of Iran.
由刚地弓形虫引起的弓形虫病是家畜和人类的一种重要疾病。在伊朗，研究表明人类刚地弓形虫感染率相对较高，其流行主要与食用未煮熟的肉类或肉制品有关。我们检测了来自伊朗西南部胡齐斯坦省中心阿瓦士各地的450份母牛血清样本。采用改良凝集试验，使用刚地弓形虫全速殖子检测针对刚地弓形虫的IgG抗体，在450头牛中有71头（15.77%）检测到抗体，其中38头牛抗体效价为1:25，18头牛为1:50，11头牛为1:100，3头牛为1:200，1头牛为1:400。两岁以上母牛的抗体效价降低。这些结果表明，胡齐斯坦省牛的刚地弓形虫感染情况相对较为严重，但不算非常高，牛肉消费可能是伊朗西南部人类感染的一个来源。
