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, serratia spp, and Citrobacter freundii were also
isolated.
All the strains were tested for sensitivity to bacitracin, carbenicillin
colistin, cephalothin, chloramphenicol, gentamicin, kanamycin, lincomycin,
trimethoprim and tetracycline. The proportion of strains sensitive and
resistant to different antibacterial agents varied widely with species of
bacteria. Most of the strains except pseudomonas spp were sensitive to few of
the antibacterial agents and posed no problem with relation to treatment.
Pseudomonas spp. were 100% sensitive to polymyxin B and colistin
(polymyxin E ) and 90% resistant to gentamicin and carbenicillin.
