The prevalence of anti-Toxoplasma gondii specific IgG in stray and household cats in Tehran was determined by Indirect Fluorescent Antibody Test (IFAT) on serum samples from 100 cats (50 stray and 50 households). Overall infection rate was 63%. The infection rate in stray cats (90%) was significantly higher (p<0.001) than that of household cats (36%). Last serum positive dilutions varied from 1: 32 to 1: 512 titres in which the highest percentage (27%) was for 1:256 and the least (4.8%) was at 1:32. The rate of infection between male and female cats of both groups was not significantly different; 90.3% versus 89.5% for male and female in stray cats, respectively. Different sexes of household cats were seropositive at the same rate (36%). A high positive correlation (r(2)=0.97) between age and the rate of infection was observed. The prevalence of Toxoplasma gondii infection in cats in Tehran was high, especially in stray cats which are probably the main source of Toxoplasma infection in this area.
通过间接荧光抗体试验（IFAT）对来自100只猫（50只流浪猫和50只家猫）的血清样本进行检测，以确定德黑兰流浪猫和家猫中抗弓形虫特异性IgG的流行情况。总体感染率为63%。流浪猫的感染率（90%）显著高于家猫（36%）（p<0.001）。末次血清阳性稀释度在1:32至1:512滴度之间，其中最高百分比（27%）为1:256，最低（4.8%）为1:32。两组中雄性和雌性猫的感染率无显著差异；流浪猫中雄性和雌性的感染率分别为90.3%和89.5%。家猫不同性别的血清阳性率相同（36%）。观察到年龄与感染率之间存在高度正相关（r(2)=0.97）。德黑兰猫中弓形虫感染的流行率很高，尤其是流浪猫，它们可能是该地区弓形虫感染的主要来源。
