摘要: 对天津市区不同公园土壤样品中弓形虫卵囊的污染情况进行调查,选取弓形虫的高拷贝DNA片段B1基因作为诊断基因,以天津市内六区共35个公园及5所高校的土壤样品作为研究对象,提取土壤样品中的基因组DNA,利用PCR方法对春夏季节以及秋冬季节的土壤样品中弓形虫卵囊的污染情况进行检测。结果表明:春夏季节土壤样品中弓形虫卵囊的阳性率为11.11%(10/90),秋冬季节土壤样品中弓形虫卵囊的阳性率为2.22%(2/90),弓形虫卵囊污染情况呈季节性变化,从春夏季节到秋冬季节呈逐渐下降的趋势。

Abstract: In order to investigate the contamination status of Toxoplasma gondii in soil samples of parks in urban areas of Tianjin city, high copy DNA fragment B1 gene of Toxoplasma gondii was selected to be the diagnostic gene, and soil samples from thirty five parks and five universities were studied as research objects. Genomic DNA was extracted from the soil samples, and the contamination status of Toxoplasma gondii oocyst in soil samples from spring-summer months and autumn-winter months were detected by PCR method. The results showed that the positive rate of soil samples from spring-summer months was 11.11% (10/90), while the positive rate of soil samples from autumn-winter months was 2.22%(2/90). The contamination of Toxoplasma gondii was seasonal, and there is a downward trend from spring-summer months to autumn-winter months.

Key words: Toxoplasma gondii, urban areas of Tianjin city, parks, soil samples, contamination
