Titres of antibody to Toxoplasma gondii were determined in 596 inhabitants of Greater Victoria who were either patients at two hospitals or healthy volunteers. The survey included 404 women of childbearing age, 305 of whom had just given birth. The proportion of persons with antibody to T. gondii at a titre of 1:8 or greater as determined by a methylene blue dye test was 28%. Titration of IgM antibody specific to T. gondii by the indirect fluorescent antibody test, performed in the serum samples with a titre of 1:8 or greater by the dye test, indicated that 3% of the 596 patients had recently acquired infection with T. gondii. The proportion of women with antibody to T. gondii among those who had just given birth was 25%, but the proportion among women aged 31 to 35 years who had just given birth was 37%.
在大维多利亚地区的596名居民中测定了弓形虫抗体滴度，这些居民包括两家医院的患者或健康志愿者。该调查包括404名育龄妇女，其中305名刚分娩。通过亚甲蓝染色试验确定，弓形虫抗体滴度为1:8或更高的人群比例为28%。对染色试验滴度为1:8或更高的血清样本进行间接荧光抗体试验，以滴定针对弓形虫的特异性IgM抗体，结果表明，596名患者中有3%最近感染了弓形虫。刚分娩的妇女中弓形虫抗体阳性的比例为25%，但在31至35岁刚分娩的妇女中这一比例为37%。
