Abstract:

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.

Gram-negative bacilli in burns.

In a period of two years, 865 strains of Gram-negative bacilli other than Pseudomonas aeruginosa isolated from burns were identified by a range of tests. The commonest species were Proteus mirabilis, Escherichia coli, and Enterobacter cloacae. Many strains of Klebsiella aerogenes, Enterobacter aerogenes, and Bacterium anitratum were also found.A large proportion of the strains were tested for s...

Aerobic Gram-Negative Bacilli

A total of 434 clinical aerobic gram-negative bacillary isolates were tested against LY127935, a new 1-oxa cephalosporin, and compared with other cephalosporins, penicillins, and aminoglycosides by a broth microdilution technique. Cefotaxime (HR756), a new semisynthetic cephalosporin, and LY127935 were more active, and showed lower minimun inhibitory concentrations (rantes, -O.12 to 2.0 ,ug/ml)...

Post-neurosurgical meningitis; gram negative bacilli vs. gram positive cocci

Background: Post-neurosurgical meningitis is a significant cause of mortality and morbidity. In this study we aimed to compare the differences of clinical, laboratory features and outcomes between the post-neurosurgical meningitis caused by gram-negative bacilli (GNB) and gram-positive cocci (GPC). Methods: Cases of post-neurosurgical meningitis (with positive CSF culture) were included. After...

Prevalence of Drug Resistance in Nonfermenter Gram-Negative Bacilli

  Background and Objectives: Non-fementer gram-negative bacilli (NFGB) are ubiquitous pathogen that has emerged as a major cause of health care associated infections. The aim of this study was to determine the prevalence and antimicrobial susceptibility of   NFGB in an Iranian hospital. Materials and Methods: FromJuly 2005 to November 2006 a total of 257 strains of NFGB including 109 (42.41%)...

The first observation is not surprising, since extrinsic allergic alveolitis is not due to a type 1 allergic reaction. The second is of interest, since it sugges...
