BACKGROUND Extended-spectrum beta-lactamase (ESBL)-producing strains of Klebsiella pneumoniae have caused major therapeutic problems worldwide since the majority are resistant to various antibiotics. In this study, an investigation was conducted regarding antibiotic-resistant patterns of 128 isolates of K pneumonile cultured from Iranian patients at two teaching hospitals during 2004-2005. MA...

Extended-spectrum β lactamases (ESBLs) continue to be a major challenge in clinical setups world over, conferring resistance to the expanded-spectrum cephalosporins. An attempt was made to study the prevalence of ESBL-producing Klebsiella pneumoniae clinical isolates in a tertiary care hospital in Kurnool. A total of hundred collected isolates of Klebsiella pneumoniae was studied for their susc...

Extended-spectrum β-lactamase (ESBL)-producing Enterobacteria has become a considerable global concern because of their potential dissemination in humans, in domestic animals, wildlife and the environment. The present study aimed to explore the ESBL producing  enterobacteria in aquatic sources of Bangladesh as the water may be the potential source of dissemination of this alarming ant...

We determined the faecal carriage of extended-spectrum beta-lactamase-(ESBL)-producing bacteria in the community in Saudi Arabia. A total of 716 faecal specimens (from 505 healthy individuals and 211 community outpatients) were screened for ESBL using the double-disk synergy test and confirmed by the Clinical Laboratory Standards Institute combined disk method. We found 91 (12.7%) isolates were...

Urinary Tract Infection (UTI) forms the largest single group of hospital acquired infections and account for about 40-50% of the total nosocomial infections. In spite of the wide spread availability of antibiotics, UTI remains to be one of the most common infectious diseases diagnosed. Further world wide data shows that there is an increasing resistance among UTI pathogens to conventional drugs...

BACKGROUND & OBJECTIVES AmpC β-lactamases are clinically significant since these confer resistance to cephalosporins in the oxyimino group, 7-α methoxycephalosporins and are not affected by available β-lactamase inhibitors. In this study we looked for both extended spectrum β-lactamases (ESBL) and AmpC β-lactamases in Klebsiella pneumoniae clinical isolates. METHODS One hundred consecutive, n...

BACKGROUND There is no information regarding the resistance mechanisms of extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae in community setting in Cameroon. The current study aimed to determine the proportion of ESBLs in Enterobacteriaceae isolated in the community and to analyse some risk factors associated with ESBL carriage. METHODS Faecal samples were collected from 208 d...

Submitted 11 Jan 2017; Accepted 6 Feb 2017; Published 13 Feb 2017 Extended-spectrum β-lactamase (ESBL)-producing Enterobacteria has become a considerable global concern because of their potential dissemination in humans, in domestic animals, wildlife and the environment. The present study aimed to explore the ESBL producing enterobacteria in aquatic sources of Bangladesh as the water may be the...

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...

BACKGROUND & OBJECTIVES Members of the genus Acinetobacter are an important cause of nosocomial infections and with widespread resistance to various antibiotics. Extended spectrum beta lactamase (ESBL) associated resistance among Acinetobacter species is now known. The aim of this study was to speciate clinical isolates of Acinetobacter, analyze their resistance patterns, identify the productio...
