Emergence of extended spectrum beta lactamases (ESBLs) producing strains of gram negative bacteria, as one of the leading cause of septicaemia often complicates the clinical and therapeutic outcome. The present study was undertaken to investigate the prevalence of ESBLs in bacteria isolated from neonatal septicaemic cases along with their antimicrobial sensitivity pattern. Blood samples were co...

Resistance to 3rd generation cephalosporins in Salmonella has been attributed to the production of extended spectrum β-lactamases (ESBLs), but AmpC and KPC or metallo β-lactamase (MBL) mediated resistance have also been reported1. ESBLs reported in Salmonella spp. are the derivatives of TEM, SHV, CTX-M and PER type β-lactamase families1. We isolated Salmonella enterica ser. Typhimurium (B9903) ...

The emergence of extended-spectrum beta-lactamase- (ESBL-) producing pathogenic bacteria at Kabale Regional Referral Hospital (KRRH), located in southwestern Uganda, is of great concern: a phenomenon that worries clinicians and other healthcare workers due to the serious threat they pose to patients. This current study aimed at determining the phenotypic detection of ESBL-producing strains of E...

A study was conducted to detect the presence of extended-spectrum beta-lactamases (ESBLs) in 706 isolates of Escherichia coli, largely from outpatients (75.2%). The Clinical and Laboratory Standards Institute (formerly NCCLS)-recommended disk diffusion procedure was used to detect ESBL presence; the VITEK 2 system (bioMérieux, Marcy L'Etoile, France) was used to determine the susceptibility to ...

Production of Extended spectrum β-lactamases (ESBLs) is a common mechanism of resistance in multidrug- Pseudomonas aeruginosa, but the frequency of different ESBLs may vary significantly in different parts of the world. The aim of this study was to investigate the prevalence of OXA-2/OXA-10 type ESBLs and class 1 integron among clinical isolates of P. aeruginosa in Ta...

objective(s) different types of extended spectrum beta-lactamases (esbls) are encountered in the clinical settings worldwide. there are a few studies regarding the prevalence of esbl genes among klebsiella pneumoniae isolates at tehran especially those of blaper and blactx. the aim of this study was to determine the prevalence of blashv, blatem ,blaper and blactx genes among clinical k. pneumon...

conclusions the results indicate that the rates of esbls are high in urine e. coli and k. pneumoniae isolates from tehran hospitals. also this study indicates that the urine isolates from male patients are significantly more resistant than the female isolates. materials and methods a total of 190 e. coli and k. pneumoniae isolates were collected from patients’ urine samples in hospitals from te...
