Petroleum hydrocarbon contamination is a major global prevalent issue in the petroleum sector. This research focuses on evaluating biodegradation of three Gram-negative bacilli, isolated from cowpea planted soil, contaminated with kerosene. The Gram negative bacilli strains have been characterized and identified, using MicrobactTM ID24E systems for the identification of Enterobacteriaceae and c...

OBJECTIVE To evaluate ertapenem disk performance to predict Klebsiella pneumonie carbapenemase production by Gram-negative bacilli. METHODS All Gram-negative bacilli isolated between January 2010 and June 2011 were tested by disk diffusion (Oxoid™) for sensitivity to ertapenem, meropenem and imipenem. Resistant or intermediate sensitivity strains (diameter < 22 mm for ertapenem) were also tes...

Current methods to isolate and identify anaerobic bacteria are laborious and time consuming. It was postulated that the short-chain fatty acids (SCFA) produced by these organisms might serve as microbial markers in clinical material. 98 specimens of pus or serous fluid were analyzed by gas-liquid chromatography, and findings were compared with culture results. Good correlations were found for t...

INTRODUCTION The increasing prevalence of multiresistant Gram-negative strains in intensive care units (ICUs) has recently rekindled interest in colistin, a bactericidal antibiotic that was used in the 1960s for treatment of infections caused by Gram-negative bacilli. We conducted the present observational study to evaluate the efficacy of intravenous colistin in the treatment of critically ill...

INTRODUCTION Isolation of common pathogens involved in ocular infection, and their in-vitro susceptibility to commonly-used ocular antibiotics, as well as the trends in antibiotic resistance developed by these pathogens, were investigated. METHODS Corneal scrapings were obtained from 318 hospitalised patients and inoculated directly onto enriched and differential culture media. Subcultures we...

background and objectives: patients at intensive-care-unit (icu) are at risk of acquiring nosocomial infections which contributes to higher rates. approximately 25% of all hospital infections and 90% of outbreaks occur in icus. multi-resistant gram-negative rods are important pathogens in icus, causing high rate of mortality. the purpose of this study was to investigate the antimicrobial resist...

181 patients undergoing resection of the oesophagus for carcinoma were randomised to receive selective decontamination (test group) or conventional perioperative antibiotic prophylaxis (controls). 114 patients were finally included in the study: 12 of 56 test patients had 18 infections, whereas 32 of 58 controls acquired 51 infections. Colonisation with aerobic gram-negative microorganisms, and...
