目的 对3例因生食青蛙致广州管圆线虫感染的病例进行研究分析,探讨广州管圆线虫病的感染途径和流行特点。方法 从2006-2010年深圳市疾病预防控制中心寄生虫门诊检测出的42例广州管圆线虫IgG抗体阳性病例资料中整理出3例因接触蛙类而感染本病的病例,对其流行病学资料、临床表现、血中嗜酸性粒细胞浓度、病变部位CT及MRI和血清免疫学特征进行研究分析。结果 接触青蛙的3例广州管圆线虫病例均为广东本地感染,因生食青蛙或用蟾蜍肉贴敷疮疡而感染。临床表现主要为发热和头痛。3例循环抗原CAg均为阳性,其中1例10 d前生食青蛙者IgM抗体阳性。而肝吸虫、肺吸虫、包虫、囊虫、弓形虫和裂头蚴抗体均为阴性。结论 接触蛙类是广州管圆线虫病感染的重要途径,感染后出现典型的临床症状和血清学特征。
Objective To analyze and analyze the cases of Acanthoela proclastus in 3 cases caused by raw food frogs and to explore the infection ways and epidemic characteristics of Acanthomysis in Guangzhou. Methods A total of 42 cases of Agrobaculium oncologia IgG detected in the parasite clinic of Shenzhen Center for Disease Control and Prevention from 2006 to 2010 were collected from 3 cases of this disease due to exposure to frogs and their epidemiology Data, clinical manifestations, blood eosinophil concentration, CT and MRI lesions and immunological characteristics of the study. Results 3 cases of contact with the frog of the Chinese angiostrongyliasis cases were local infection in Guangdong, due to raw food frogs or toad meat sticking sore and infection. The main clinical manifestations of fever and headache. 3 cases of circulating antigen CAg were positive, of which 1 case of raw food frog IgM antibody positive 10 d. The liver flukes, paragonimiasis, hydatid, cysticercosis, Toxoplasma gondii and anti-spirer antibodies were negative. Conclusions Exposure to frogs is an important route of infection of angiostrongylus cantonensis in Guangzhou. Typical clinical symptoms and serological features appear after infection.
