Aztreonam is a new monobactam antibiotic which is highly active against aerobic Gram negative bacilli. The purpose of this study is to establish the in-vitro activity of aztreonam against recent clinical isolates of aerobic Gram negative bacilli obtained from patients at the Kuala Lumpur General Hospital. Minimum inhibitory concentrations of the antibiotic against the isolates were determined u...

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, ...

BMY-28142 was compared with other broad-spectrum antibiotics against gram-positive cocci and gram-negative bacilli. BMY-28142 was highly active against all gram-negative bacilli and especially against Enterobacter cloacae, Serratia marcescens, and Morganella morganii. Its in vitro activity suggests that BMY-28142 should prove to be useful for the treatment of gram-negative bacillary infections.

background: the role of the hospital environment as a source of dissemination of pathogens is critical. environmental surfaces in the intensive care units (icus) are suitable for the growth of gram-negative bacteria that normally circulate between the environment and patients and can cause outbreaks of nosocomial infections. in this study, the prevalence of gram-negative bacilli in the environm...

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...

Abstract Background The aim of this study was to compare the performance new flow cytometer UF-5000 with UF-1000i and Gram staining for determining bacterial patterns in urine samples. Methods Women who attended our clinic symptoms suggestive urinary tract infection were enrolled study. Mid-stream samples collected gram staining, analysis cultures. Bacterial classified using (none, cocci bacter...

Emergence of the newly identified 16S rRNA methylases RmtA, RmtB, and ArmA in pathogenic gram-negative bacilli has been a growing concern. ArmA, which had been identified exclusively in Europe, was also found in several gram-negative pathogenic bacilli isolated in Japan, suggesting global dissemination of hazardous multiple aminoglycoside resistance genes.

Sixty-nine positive cultures were obtained from sixty-nine specimens of sputum from practically all stages of tuberculosis. Six of these specimens were negative by direct microscopic examination, but the cultures gave positive findings. These six specimens have been positive for tubercle bacilli at some time. Nineteen positive cultures were isolated from thirty-two specimens of feces. All these...

Aerobic gram-negative bacilli isolated from clinical specimens from 1 January to 31 December 1976 were tested for gentamicin and tobramycin resistance by standardized disk testing. For Pseudomonas isolates, gentamicin resistance was 17.1% and tobramycin resistance was 2.8%. For other gram-negative bacilli, gentamicin resistance was 5.5% and tobramycin resistance was 5.4%. Seventy-four patients ...
