Occurrence of chloramphenicol-acetylating enzymes in various gram-negative bacilli.
The occurrence of a chloramphenicol-acetylating enzyme, similar to that found in Escherichia coli, carrying an R factor was investigated in various gram-negative bacilli. The acetylated products of chloramphenicol were identified by chromatography and quantitatively assayed after benzene extraction. The investigated strains were of the Salmonella-Arizona group, the Klebsiella-Aerobacter group, ...
متن کاملGRAM NEGATIVE BACILLI IN BURNS
In a period of nine months, 225 strains of Gram-negative bacilli isolated from burns were identified by a variety of tests in two burn centers in Tehran. The most common species were Pseudomonas aeruginosa, Pseudomonas fluorescens, Escherichia coli, Enterobacter agglomerans, Enterobacter cloacae and Klebsiella pneumoniae. Many strains of acinetobacter spp, providencia spp, proteus spp, ser...
