Toxoplasmosis, an infection caused by Toxoplasma (T.) gondii Apicomplexa protozoan, is widespread in humans and other animal species, having already been reported in many countries and different climates. In Pakistan, no data is available on this aspect among food animals. This study was undertaken to determine the seroprevalence of T. gondii infection in sheep and goats. A total of 200 serum samples from sheep and goats, were collected from urban area of Rahim Yar Khan (Punjab), Pakistan and tested for Toxoplasmosis with a commercial latex agglutination kit (Eiken Chemical Co., Ltd. Japan). The overall seroprevalence of Toxoplasmosis was 19%. Goats had a significantly higher (p < 0.01) prevalence (25.4%) as compared to the sheep (11.2%); and higher (p < 0.01) in the female (24%) than in the males (19%) for both species. In the present study the male (both in sheep and goat) are found less seropositive T. gondii (OR = 0.23; 99% C.I. = 0.01, 1.81) as compared to female sheep and goat. The prevalence was significantly higher (p < 0.01) in adult sheep than younger animals. Among both the sheep and goats the group from 1-1.5 years are highly seropositive (OR = 1.75; 99% C.I. = 0.47, 6.51) as compared to the group less than one year of age followed by the 2-2.5 years age group (OR = 1.63; 99% C.I. = 0.50, 5.74) whereas group with more than 3 years of age least seropositive.
弓形虫病是由刚地弓形虫这种顶复门原生动物引起的一种感染，在人类和其他动物物种中广泛存在，许多国家和不同气候条件下均有相关报道。在巴基斯坦，关于食用动物这方面尚无数据。本研究旨在确定绵羊和山羊中弓形虫感染的血清阳性率。从巴基斯坦旁遮普省拉希姆亚尔汗市区采集了共200份绵羊和山羊的血清样本，并用商用乳胶凝集试剂盒（日本荣化学株式会社）检测弓形虫病。弓形虫病的总体血清阳性率为19%。与绵羊（11.2%）相比，山羊的患病率显著更高（p<0.01）（25.4%）；两个物种中雌性（24%）的患病率均高于雄性（19%）（p<0.01）。在本研究中，与雌性绵羊和山羊相比，雄性（绵羊和山羊）的弓形虫血清阳性率较低（OR = 0.23；99%置信区间 = 0.01，1.81）。成年绵羊的患病率显著高于幼龄动物（p<0.01）。在绵羊和山羊中，1至1.5岁组的血清阳性率极高（OR = 1.75；99%置信区间 = 0.47，6.51），高于小于1岁的组，其次是2至2.5岁年龄组（OR = 1.63；99%置信区间 = 0.50，5.74），而3岁以上组的血清阳性率最低。
