as a food-borne pathogen, the infection of it in food animals has relation with human toxoplasmosis, but the trends and epidemiological features of infections in food animals are rarely studied in China. The aimed of this study was to assess the epidemiology and risks of in sheep, goats, swines, chickens, yaks, cattle and humans from 2000 to 2017 and to explore prevention and control strategies. The overall seroprevalence of infections in food animals is 23.7% (39,194/165,417, 95%CI, 23.49-23.90%), which is significantly higher than that in humans (8.2%, 95%CI, 8.06-8.39%, 8,502/103,383) ( < 0.0001). Compared the prevalence of infections in animals and humans sampled from 2000 to 2010, it was significantly increased in the period 2011 to 2017 ( < 0.0001). Compared the food animals from non-Yangtze River, animals from regions of the Yangtze River have high seroprevalence rates for ( < 0.0001). Furthermore, samples from the western to eastern regions of the Yellow River showed an increase in seroprevalence for ( < 0.0001). It was speculated that oocysts may be transmitted by water and annual precipitation possible help the oocyst spread and retain accessible for potential hosts. Effective prevention and control strategies are including water filtration or water boiling, inactivating oocysts from feline's feces, monitoring birds and rodents. (ToxoDB#9) is the predominant genotype in food animals from China.
作为一种食源性病原体,其在食用动物中的感染与人类弓形虫病有关,但在中国,食用动物感染的趋势和流行病学特征鲜有研究。本研究旨在评估2000年至2017年绵羊、山羊、猪、鸡、牦牛、牛及人类中弓形虫感染的流行病学情况及风险,并探索预防和控制策略。食用动物中弓形虫感染的总体血清阳性率为23.7%(39194/165417,95%置信区间,23.49 - 23.90%),显著高于人类(8.2%,95%置信区间,8.06 - 8.39%,8502/103383)(P < 0.0001)。比较2000年至2010年采样的动物和人类中弓形虫感染的患病率,2011年至2017年期间显著增加(P < 0.0001)。与非长江流域的食用动物相比,长江流域地区的动物弓形虫血清阳性率较高(P < 0.0001)。此外,黄河流域从西到东的样本弓形虫血清阳性率呈上升趋势(P < 0.0001)。据推测,弓形虫卵囊可能通过水传播,年降水量可能有助于卵囊传播并保持对潜在宿主的可及性。有效的预防和控制策略包括水过滤或水煮、灭活猫粪便中的卵囊、监测鸟类和啮齿动物。(ToxoDB#9)是中国食用动物中的主要基因型。
