In 1990, 1443 sera randomly selected by computer generated random numbers from a bank of greater than 15,000 sera collected earlier from sows at slaughter in various geographic regions of Canada were tested for anti-Toxoplasma immunoglobin G (IgG) by the modified direct agglutination test. One hundred and thirty-six (9.4%) samples were positive for anti-Toxoplasma IgG while 36 (2.5%) of the sera gave borderline reactions. The highest prevalence of anti-Toxoplasma IgG was in swine originating in the Atlantic provinces and Ontario while the lowest was in swine from Manitoba and Saskatchewan.
1990年，通过计算机生成随机数从加拿大不同地理区域早期屠宰母猪时采集的15000多份血清库中随机选取1443份血清，采用改良直接凝集试验检测抗弓形虫免疫球蛋白G（IgG）。136份（9.4%）样本抗弓形虫IgG呈阳性，36份（2.5%）血清出现临界反应。抗弓形虫IgG患病率最高的是来自大西洋省份和安大略省的猪，而最低的是来自曼尼托巴省和萨斯喀彻温省的猪。
