چکیده
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 antimicrobial resistance. a total of 94 water samples (53 tube well and 41 supplied water) were collected from 35 districts of bangladesh from which 60 enterobacter were isolated based on their biochemical profile. among these 36 were enterobacter sp and 24 were e coli. 73% of the isolates were multidrug resistant (mdr) as revealed by antimicrobial susceptibility test whereas 29% of these mdr isolates were phenotypically detected as esbl producing as observed by double disk synergy test (ddst) test. the esbl type shv was found to be dominant among the isolates revealed by pcr. therefore, strategies can be employed to reduce the dissemination of esbl producing bacteria in the aquatic sources which may threaten the human life, animal and surrounding environment.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 antimicrobial resistance. a total of 94 water samples (53 tube well and 41 supplied water) were collected from 35 districts of bangladesh from which 60 enterobacter were isolated based on their biochemical profile. among these 36 were enterobacter sp and 24 were e coli. 73% of the isolates were multidrug resistant (mdr) as revealed by antimicrobial susceptibility test whereas 29% of these mdr isolates were phenotypically detected as esbl producing as observed by double disk synergy test (ddst) test. the esbl type shv was found to be dominant among the isolates revealed by pcr. therefore, strategies can be employed to reduce the dissemination of esbl producing bacteria in the aquatic sources which may threaten the human life, animal and surrounding environment.

متن کاملMultiple Antibiotic-Resistant, Extended Spectrum-β-Lactamase (ESBL)-Producing Enterobacteria in Fresh Seafood
Members of the family Enterobacteriaceae include several human pathogens that can be acquired through contaminated food and water. In this study, the incidence of extended spectrum β-lactamase (ESBL)-producing enterobacteria was investigated in fresh seafood sold in retail markets. The ESBL-positive phenotype was detected in 169 (78.60%) isolates, with Escherichia coli being the predominant spe...
متن کاملPhenotypic and genotypic studies of extended spectrum beta-lactamase (ESBL) resistance among Salmonella isolates from poultry sources in Iran
BACKGROUND: Poultry and poultry products are among the major sources of Salmonella infections for humans. Increasing occurrence of antimicrobial resistance among Salmonellae has become a serious public health concern. The detection of extended spectrum b-lactamase (ESBL) producers among Salmonella spp. has increased in recent years. OBJECTIVES: The purpose of this study was to investigate the a...
متن کاملDetection of extended-spectrum beta-lactamase (ESBL)-producing strains by the Etest ESBL screen.
Resistance to contemporary broad-spectrum beta-lactams, mediated by extended-spectrum beta-lactamase (ESBL) enzymes, is an increasing problem worldwide. The Etest (AB Biodisk, Solna, Sweden) ESBL screen uses stable gradient technology to evaluate the MIC of ceftazidime alone compared with the MIC of ceftazidime with clavulanic acid (2 micrograms/ml) to facilitate the recognition of strains expr...
