目的通过蚊虫叮咬宿主附红细胞体进入蚊体内感染的研究,评价蚊虫在附红细胞体病流行过程中的作用。方法在不同生境捕捉吸血蚊,在蚊胃血、胸、唾液腺压片检查附红细胞体,计算感染率。结果年均人房蚊密度为16.6只/间.人工小时,畜房为105.44只/间.人工小时。共解剖965只,在蚊胃血阳性率为72.12%;在胸、唾液腺阳性率为30.16%。其中人房帐内捕蚊273只,在蚊胃血阳性率为53.11%,在胸、唾液腺阳性率为21.98%;畜房捕蚊692只,在蚊胃血阳性率为79.62%,在胸、唾液腺阳性率为33.38%。人房、畜房、野外感染率有差异(χ2=131.56,P<0.005)。人房帐内平均吸血率为57.23%,平均叮咬人率为0.48只/人.天。结论蚊虫在传播附红细胞体中具有一定的媒介作用。
Objective To study the role of mosquitoes in the pathogenesis of eperythrozoonosis by mosquito bite host Eperythrozoon infection into mosquito. Methods The mosquitoes were caught in different habitats, and the eperythrozoon was examined in the stomach, chest and salivary glands of the mosquito, and the infection rate was calculated. Results The annual average mosquito density of mosquitoes was 16.6 / man-made hour, 105.44 house / man-hour. A total of 965 were dissected, and the positive rate in mosquito and stomach was 72.12%. In the chest and salivary gland, the positive rate was 30.16%. Among them, 273 mosquitoes were collected in the human room, the positive rate was 53.11% in the mosquito and stomach, 21.98% in the chest and salivary glands, 692 in the cat house, and the positive rate in mosquito and stomach was 79.62% The positive rate of salivary glands was 33.38%. There was a significant difference in the prevalence rates of human and animal houses (χ2 = 131.56, P <0.005). The average rate of aspiration in the room was 57.23% and the average rate of bites was 0.48 / person. Conclusion The mosquito plays a mediating role in the transmission of Eperythrozoon.
