蓝氏贾第虫为肠道原虫,目前公认对人类有致病性。感染后常出现急性腹泻,潜伏期约12-19天,慢性时也可伴发明显的胃肠症状,临床一般根据粪便内见有包囊或十二指肠引流物中找到滋养体而确诊。为评价本病的流行性及确定其感染的临床病理学相互关系,作者对意大利东北部Feltre城医院1986.1-91.12期间,11085例上消化道内镜检查患者的15023份胃活检标本中病原体进行了前瞻和回顾性分析。
Giardia lamblia is an intestinal protozoan, is currently recognized for human pathogenicity. Acute diarrhea often occurs after infection, the incubation period of about 12-19 days, chronic may also be associated with significant gastrointestinal symptoms, clinical generally found in feces within the capsule or duodenal drainage to find trophozoites and confirmed. To assess the epidemiology of the disease and to determine its clinical and pathological correlation with the infection, the authors conducted a survey of pathogens in 1,502 gastric biopsy specimens of 1,105 patients with upper gastrointestinal endoscopy during the period 1986.1-91.12 in Feltre City Hospital, Northeastern, Italy Prospective and retrospective analysis.
