Defining multidrug resistance in Gram-negative bacilli

GRAM 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...

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%)...

multidrug resistant gram-negative bacilli in lower respiratory tract infections.

background: lower respiratory tract infections are among important causes of morbidity and mortality for all age groups. the emergence of multidrug resistant gram-negative bacilli is an issue of increasing concern. materials and methods: a retrospective study including respiratory specimens (sputum and bal) was conducted in our tertiary care centre. samples were processed for microscopy, cultur...

Aminoglycoside Resistance in Gram-negative Bacilli

Aminoglycosides are one of the clinically relevant antibiotics. They kill bacteria by binding to bacterial 30S subunit of ribosome. Resistance to aminoglycosides occurs by three different mechanisms: 1. Production of an enzyme that modifies aminoglycosides, 2. Impaired entry of aminoglycoside into the cell by altering the OMP permeability, decreasing inner membrane transport, or active efflux, ...
