在支气管扩张或囊性纤维化患者病势加剧期间,通常只分离到绿脓杆菌。而出人意外的是在一般抗绿脓杆菌无效时,应用氯霉素或红瓣素却可改善临床状况。这可能因后者杀死了在绿脓杆菌之外的,对氯霉素敏感的病原细菌之故。绿脓杆菌,尤其是其中的粘液型菌株,在普通的细菌学培养基上生长得非常丰盛,以致影响了检材中其他细菌的生长和分离检出。 Pseudomonas aeruginosa is usually isolated during exacerbations of patients with bronchiectasis or cystic fibrosis. The surprising is that in general, anti-Pseudomonas aeruginosa invalid, the application of chloramphenicol or erythromycin can improve the clinical status. This may be due to the fact that the latter killed chloramphenicol-sensitive pathogenic bacteria outside of Pseudomonas aeruginosa. Pseudomonas aeruginosa, especially the mucoid strains therein, grow very abundantly in ordinary bacteriological medium, so as to affect the growth and the isolation of other bacteria in the test material.
