2012年杭州市宠物饲养者弓形虫病感染状况分析

A survey on Toxoplasma gondii infection of pet feeders in Hangzhou in 2012

目的了解杭州市宠物饲养人群弓形虫感染现状及其影响因素。方法采集2012年杭州市宠物饲养人群标本528份，使用ELISA方法检测弓形虫IgG抗体，同时进行流行病学问卷调查。结果宠物饲养人群弓形虫感染率为3．03％，不同性别、职业之间感染率差异无统计学意义。但各年龄组人群弓形虫感染率差异有统计学意义（X2=17．403，P：0．001），感染率呈现随文化程度增高而下降的趋势（r=7．592，P=0．022）。捡拾落地食品不洗就吃、生吃或半生吃其他动物肉（狗肉、蛙肉、蛇肉、羊肉、鼠肉、野猪肉）可增加弓形虫感染率（X2=6．92～8．79，P〈0．01）。结论杭州市宠物饲养人群弓形虫的感染率低于本市既往调查水平，感染与不良饮食、卫生习惯有关。

Objective To determine the seroprevalence of T. gondii and its risk factors for the human infection in Hangzhou. Methods Questionnaire of 528 pet feeders was conducted in Hangzhou. Serum samples were tested for IgG antibodies to T. gondii by ELISA. Results The positive rate of IgG antibodies to T. gondii was 3.03% （16/528） in pet feeders. The differ- ence was not significant in the positive rates between male and female, among different occupations. The difference of positive rates was significant among different age groups（x2 = 17. 403 ,P = 0.001 ）. The infection rate decreased with the increase in ed- ucational level（x2 = 7. 592, P = 0. 022）. Directly eating the food falling to the ground and taking raw or semi - raw meat showed the significant influence upon T. gondii infection （X2 = 6.92 - 8.79,P 〈 0.01 ）. Conclusion The seroprevalence of T. gondii in pet feeders was lower than the average level in the past in Hangzhou. Human infection of T. gondii is related to unhealthy habits and behaviors in Hangzhou.
