Abstract

Strains of Pseudomonas producing fluorescin but no pyocyanin or pyorubrin were studied by biochemical and antibiotic sensitivity testing. A rapid nitrate test was found to be useful in distinguishing P. aeruginosa (positive) from P. fluorescens and P. putida (both negative). A shortened gelatin test differentiated P. fluorescens (positive) from P. putida (negative). P. fluorescens and P. putida were very sensitive to low levels of kanamycin and resistant to carbenicillin, a pattern just the opposite of that obtained with P. aeruginosa.

摘要

通过生化和抗生素敏感性测试对产生荧光素但不产生绿脓菌素或脓紫红素的假单胞菌菌株进行了研究。发现快速硝酸盐试验有助于区分铜绿假单胞菌(阳性)与荧光假单胞菌和恶臭假单胞菌(均为阴性)。缩短的明胶试验可区分荧光假单胞菌(阳性)与恶臭假单胞菌(阴性)。荧光假单胞菌和恶臭假单胞菌对低水平卡那霉素非常敏感,对羧苄青霉素耐药,这一模式与铜绿假单胞菌的情况正好相反。
