目的调查静脉吸毒人群隐孢子虫的感染情况,初步研究性别、年龄、民族和吸毒年限与感染的关系。方法收集静脉吸毒者粪便标本500份,采用改良抗酸染色法检查粪便中的隐孢子虫卵囊。结果500份粪便中84份查到隐孢子虫卵囊,总感染率为16.8%;不同性别、年龄和民族的吸毒者隐孢子虫感染率有一定差别,但差异无统计学意义;随着吸毒时间的延长,隐孢子虫感染率也相应增高,不同吸毒年限感染率差异有统计学意义。结论静脉吸毒人群隐孢子虫的感染率高于普通人群,应加强对该人群的防治工作。
Objective To investigate the infection of Cryptosporidium parvum in intravenous drug addicts and to study the relationship between sex, age, ethnicity, drug addiction duration and infection. Methods 500 copies of stool samples from intravenous drug users were collected. Cryptosporidium oocysts in stool samples were examined by modified acid-fast staining. RESULTS: Cryptosporidium oocysts were found in 84 out of 500 stool samples, with a total infection rate of 16.8%. The infection rates of Cryptosporidium among different sexes, ages and ethnic groups were different, but the difference was not statistically significant. With the extension of time, the infection rate of Cryptosporidium also increased correspondingly, and there was significant difference in the infection rates among different years of drug use. Conclusion The prevalence of cryptosporidiosis in intravenous drug users is higher than that in the general population, and prevention and treatment of this population should be strengthened.
