Parasitic infection due to Giardia lamblia can produce severe, disabling gastrointestinal symptoms. Outbreaks have been linked to contaminated municipal water supplies and situations involving person-to-person contact. Immunocompromised patients are especially at risk. Because microscopic examination of stool detects the parasite in only about half of infected patients, use of enzyme-linked immunosorbent assay to detect Giardia-specific antigen is becoming increasingly popular. In most patients, therapy with quinacrine (Atabrine) hydrochloride, metronidazole (Flagyl, Protostat), or a combination of the two is effective.
由蓝氏贾第鞭毛虫引起的寄生虫感染可产生严重的、使人衰弱的胃肠道症状。疫情爆发与受污染的市政供水以及人与人接触的情况有关。免疫功能低下的患者尤其危险。由于仅约一半的受感染患者通过粪便显微镜检查能检测到该寄生虫，因此使用酶联免疫吸附测定法检测贾第虫特异性抗原越来越普遍。对大多数患者而言，用盐酸阿的平、甲硝唑或两者联合治疗是有效的。
