Characterization of the Extended-Spectrum beta-Lactamase Producers among Non-Fermenting Gram-Negative Bacteria Isolated from Burnt Patients
Background & Aims of the Study: Extended-spectrum beta-Lactamases (ESBLs) represent a major group of beta-lactamases which are responsible for resistance to oxyimino-cephalosporins and aztreonam and currently being identified in large numbers throughout the world. The objective of this study was to characterize ESBL producers among non-fermenter gram-negative bacteria isolated from burnt patien...
متن کاملAntimicrobial resistance among non-fermenting Gram-negative bacteria in Saudi Arabia.
OBJECTIVES Non-fermentative Gram-negative bacilli (non-fermenters) can cause serious healthcare-associated infections and are often resistant to multiple antibiotics. We examined resistance rates among these bacteria from different regions of Saudi Arabia. METHODS A cross-sectional study between January and December 2009 examined 8908 clinical non-fermenters from 24 hospitals across Saudi Ara...
متن کاملBlood Group Activity of Gram-negative Bacteria
Distribution of blood group A, B, and H(O) activities among 282 aerobic Gram-negative bacteria, many isolated from the blood of patients, has been studied. Almost half of these bacteria were found to be blood group active. About 10 per cent of the organisms exhibited high, disproportional activities, which in some instances approached those of crude human blood group mucoids. No significant, sp...
متن کاملOuter-membrane pore-forming proteins in gram-negative anaerobic bacteria.
The outer-membrane proteins (OMPs) of bacteria function as the dynamic interface between the bacterium and its surroundings and are involved in maintenance of cell structure, binding a variety of substances, adhesion to other cells, and regulation of transport of both nutrients and bactericidal agents. There is a vast amount of information about aerobic OMPs and their roles in immunogenicity, v...
متن کاملMolecular Identification of ESBLs Genes (blaTEM, blaSHV and blaCTX) among Non-fermenting Gram-negative Bacteria Isolated from Hospitalized Patients in Mazandaran Province, Iran
Background and purpose: Production of beta-lactamase enzymes by bacteria, especially Extended-spectrum β-lactamases (ESBLs) is one of the major problems worldwide. ESBLs are mostly located on bacterial plasmids and it is recognized that SHV, TEM, and CTX-M are prevailing among them. The aim of this study was to determine the ability to produce ESBLs genes based on molecular method among non-fer...
