Background Group 3a/b cephalosporins are currently being used in the treatment of UTI and urosepsis. However, Extended Spectrum Beta-Lactamase (ESBL) mediated resistance has been increasingly reported among uropathogens from HIV patients. We sought to determine the incidence of ESBL genesblaCTX-M, blaTEM and blaSHV among E. coli isolates from HIV (with increased exposure to cephalosporins) and ...

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...

BACKGROUND Excessive consumption of antimicrobial materials in hospitals is considered as the main encoder leading to the emergence, development and acquisition of new bacterial resistance to beta-lactamase. OBJECTIVES Owing to the lack of proper information regarding the mechanism of the bacterial resistance to antibiotics and responsible genes in the country, the current study aimed to cons...

INTRODUCTION Pseudomonas aeruginosa is as an important opportunistic human pathogen, which is associated with several clinical infections that are usually difficult to treat because of resistance to multiple antimicrobials. The production of extendedspectrum ß-lactamases (ESBLs) is an important mechanism of ß-lactam resistance. The aims of this study were to determine the prevalence of ESBLs, a...

BACKGROUND The present study aimed to determine the occurrence of human disease-causing enteric bacteria on raw vegetables, fruits, meats, and milk products sold in Indian markets. The study further aimed to analyze antibiotic resistance rates and the presence of blaCTX-M, blaTEM, blaSHV, and blaAmpC. METHODOLOGY Twenty-three food-borne and 23 clinical isolates were compared for antibiotic re...

Aim: The present study was conducted to record the association of extended spectrum β-lactamases (ESBLs) producing enteric bacteria with diarrhea of poultry birds in Mizoram, India. Materials and Methods: Fecal samples were collected from poultry birds with the history of diarrhea from different parts of Mizoram. Samples were processed for isolation and identification of Escherichia coli, Salmo...

The presence of antibiotic resistance genes (ARGs) including those expressing ESBLs and AmpC-β-lactamases in Escherichia coli inhabiting the aquatic environments is a serious health problem. The situation is further complicated by the fact that ARGs can be easily transferred among bacterial species with the help of mobile genetic elements - plasmids, integrons, insertion sequences (IS), and tra...

Background & Aims: One of the most common causes of bacterial resistance to beta-lactam antibiotics is beta-lactamase producing. The aim of this study was to compare the antibiotic resistance of urinary Escherichia coli (E. coli) isolates producing CTX-M and TEM type beta-lactamases, and to determine the strains with co-resistance to multiple antibiotics in Mashhad, Iran. Methods: E. coli b...
