肺部的纤维化囊肿发病率和死亡率是较高的,特别是慢性绿脓杆菌感染的患者更是如此。初期,典型的非粘液样绿脓杆菌隐性感染,随后形成粘液样变异,使病情间歇加重,进一步恶化。绿脓杆菌的早期检测可以决定纤维化囊肿病人的预后,对拟定治疗方案,了解肺部感染的病原体等,有着重要的意义。绿脓杆菌感染肺部后可以通过胃肠道进入粪便,因此能在粪便中检测绿脓杆菌,达到间接诊断的目的。如果在呼吸道尚未发现绿脓杆菌前,在粪便中检测到了绿脓杆菌,它将是一个有价值的情报。作者在1987年2月至9月期间调查了54例年龄在2个月至33岁之间的未经抗菌素治疗的纤维化囊肿病人。已知其中几例有粘液样和非粘液样绿脓杆 The incidence and mortality of fibrotic cysts in the lungs are high, especially in patients with chronic Pseudomonas aeruginosa infection. Early, the typical non-mucoid Pseudomonas aeruginosa recessive infection, followed by the formation of mucoid-like variation, so that intermittent illness, further deterioration. Pseudomonas aeruginosa early detection can determine the prognosis of patients with fibrocystic degeneration, the proposed treatment plan, to understand the pathogens of lung infection, has important significance. Pseudomonas aeruginosa infection of the lungs can enter the feces through the gastrointestinal tract, it can detect Pseudomonas aeruginosa in the feces, to achieve the purpose of indirect diagnosis. If Pseudomonas aeruginosa is detected in the stool before the respiratory tract has not been found, it will be a valuable intelligence. The authors investigated 54 non-antibiotic fibrotic cysts between the ages of 2 months and 33 years from February to September 1987. Several of these are known to have mucoid and non-mucoid green pus rods
