久已认为家蝇可能是沙眼高度流行地区的传染媒介,业已注意到在某些地区沙眼流行增多的季节,亦正是家蝇最多的时期。近来作者已从患有活动性沙眼的儿童眼睛周围捕获的家蝇身上分离出沙眼衣原体。作者为确定在实验室的条件下家蝇能否携带具有活性的沙眼衣原体能持续多长时间,并以动物模型来确定家蝇是否能将沙眼衣原体从一眼传播到另一眼。作者用一种普通家蝇(Musca domestica)作研究。将该种蝇蛹壳的外表用5%石炭酸冲洗消毒,尔后放入带有纱布的无菌罐,待羽化成蝇时将流行地区的沙眼衣原体A及B型为感染家蝇的
Houseflies have long been considered as vectors of highly endemic areas of trachoma and have noticed the season of increased trachoma in some areas and the largest period of houseflies. Recently, the authors have isolated C. trachomatis from houseflies captured around the eyes of children with active trachoma. To determine how long a housefly can carry active C. trachomatis under laboratory conditions and how long the housefly can propagate C. trachomatis from one eye to another, animal models are used to determine if house fly can carry Chlamydia trachomatis. The authors used a common Musca domestica as a study. The appearance of the shell of the fly pupal shell washed with 5% carbolic acid disinfection, and then placed in a sterile tank with gauze to be feather into the fly when the prevalence of Chlamydia trachomatis type A and B are infected housefly
