目的了解四川省地震藏区6县鼠类旋毛虫感染状况,探讨鼠类与人体旋毛虫感染的关系,为藏区旋毛虫病防治工作提供科学依据。方法①走访、查看鼠痕、鼠迹,了解当地鼠只活动情况与密度;②采用鼠笼、鼠夹于藏民住宅、室外、猪圈、田间、地头捕鼠;傍晚7时布笼或夹,清晨7 8时收鼠;③处死鼠只、鉴定鼠种、剥皮、分别取每鼠膈、肋、胸、腿、舌、颈等6个不同部位横纹肌绿豆大小2块备检;④采用肌肉直接压片法与人工胃液消化法检查旋毛虫囊包。结果在地震灾区的汶州、茂县、理县、马尔康、黑水、丹巴等6县捕获黄胸鼠、褐家鼠、黑线姬鼠、川西长尾鼯、小家鼠、松鼠等7种鼠198只,经肌肉直接压片法与人工胃液消化法均未检获旋毛虫囊包。结论首次对四川省曾有旋毛虫病疫情发生的黑水、马乐康、丹巴3县,与至今未见该病报道的汶川、茂县、理县3县部份藏区进行鼠类旋毛虫感染调查均未检获旋毛虫囊包,此结果与国内部分旋毛虫病省区的同类调查结果一致。提示在旋毛虫病呈点状、散在分布的藏区,对捕获的鼠只难以检出旋毛虫囊包。
Objective To understand the status of Trichinella spiralis infection in 6 counties in Sichuan Province and discuss the relationship between the infection of Trichinella spiralis and human and to provide a scientific basis for the prevention and control of Trichinella spiralis in Tibetan area. Methods (1) Visits and traces of mouse and mouse were observed to understand the activity and density of local rats; (2) Squirrels and rats were caught in Tibetan houses, outdoor, pigsty, , Rats were sacrificed at 7:00 in the morning; ③ mice were sacrificed and the mice were identified and stripped of skin. Tissue samples of 6 different parts of the striated muscle, mung bean, were prepared for each rat diaphragm, rib, chest, leg, tongue and neck. Direct compression method and artificial gastric juice digestion method to check Trichinella pouch. Results Seven species of Rattus flavipectus, Rattus norvegicus, Apodemus agrarius, Chuanxiong longweijian, Mus musculus and squirrel were captured in 6 counties including Wenzhou, Maoxian, Lixian, Malcolm, Heishui and Danba in the earthquake- 198 rats, the muscle direct compression method and artificial gastric juice digestion were not detected Trichinella bag. Conclusions The investigation of Trichinella spiralis infection in the three Tibetan counties of Wenchuan, Maoxian and Lixian counties in Heilongjiang, Trichinella sac were not seized, the results of the domestic part of the same area of Trichinella investigation of the same. Tip Trichinella was dotted, scattered distribution of Tibetan areas, the captured mice were difficult to detect Trichinella bag.
