纤维化囊肿患者的支气管肺炎主要是由金黄色葡萄球菌、流感嗜血杆菌、铜绿假单胞菌和洋葱假单胞菌引起。住院病人调查表明由于使用广谱抗生素后,改变人体的正常菌群,往往导致真菌繁殖造成念珠菌深部或浅部感染。而纤维化囊肿病人中,尽管使用了广谱抗生素,但念珠菌的感染非常罕见。作者根据此临床现象及有关洋葱假单胞菌、荧光假单胞菌、产金色(或金色)假单胞菌等菌株有抗真菌活性的报道,收集纤维化囊肿患者痰液中分离的10株铜绿假单胞菌,9株洋葱假 Bronchopneumonia in patients with fibrocystic cyst is caused mainly by Staphylococcus aureus, Haemophilus influenzae, Pseudomonas aeruginosa and Pseudomonas cepacia. In-patient studies have shown that changing the body’s normal flora as a result of the use of broad-spectrum antibiotics often results in fungal infections that cause deep or shallow candida infections. In patients with fibrocystic cysts, Candida infections are rare, despite the use of broad-spectrum antibiotics. Based on this clinical phenomenon and the reports of antifungal activity of strains such as Pseudomonas cepacia, Pseudomonas fluorescens, and Pseudomonas fluorescens, 10 strains isolated from sputum from patients with fibrocystic cysts Pseudomonas aeruginosa, 9 onion false
