Escherichia coli O157:H7 is an important agent of haemorrhagic colitis and haemolytic uraemic syndrome in children less than five years old and elderly people. The objective of this study was to investigate the prevalence of verotocytoxin producing E. coli 0157 (VTEC O157) among human patients with diarrhoea in Morogoro, Tanzania. Faecal samples originating from 275 human patients with diarrhoe...

INTRODUCTION Antibiotic resistant mutants producing extended-spectrum beta-lactamase (ESBL) have emerged among Escherichia coli and Klebsiella pneumoniae. This study was done to determine the frequency of ESBL-producing E coli and K pneumoniae species isolated from urine samples of our patients. MATERIALS AND METHODS A study was conducted on 164 urine isolates (124 E coli and 40 K pneumoniae)...

Aim This study describes the prevalence of Escherichia coli in frozen chicken meat intended for human consumption with emphasis on their virulence determinants through detection of the virulence genes and recognition of the extended-spectrum β-lactamase (ESBL) encoding genes (blaOXA and blaTEM genes). Materials and Methods A total of 120 frozen chicken meat samples were investigated for isola...

OBJECTIVES Escherichia coli belonging to clonal group ST131 has emerged as a significant contributor to infection caused by antibiotic-resistant E. coli worldwide. We investigated the risk factors for infections caused by ST131 E. coli and their clinical implications. METHODS One thousand and seventy-seven E. coli isolates were screened for ST131 by molecular methods. Risk factors for ST131 w...

BACKGROUND In recent years, the world has seen a surge in extended-spectrum β-lactamase (ESBL)-producing bacteria. However, data on the dissemination of ESBL-producing Enterobacteriaceae in the community from systematically enrolled study subjects in Africa remains limited. To determine the prevalence, phenotypic resistance patterns and genetic characteristics of ESBL-producing E. coli and K. p...

Extended-spectrum β-lactamase producing Escherichia coli (ESBL-E. coli) were isolated from infants hospitalized in a neonatal, post-surgery ward during a four-month-long nosocomial outbreak and six-month follow-up period. A multi-locus variable number tandem repeat analysis (MLVA), using 10 loci (GECM-10), for 'generic' (i.e., non-STEC) E. coli was applied for sub-species-level (i.e., sub-typin...

Ready-to-eat (RTE) foods are widely marketed in China and important components of everyday diet. In this study, a total 2000 RTE food samples were analyzed, 252 (12.60%) which positive for Enterobacteriaceae, 48 identified as containing extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolates. Furthermore, the antimicrobial resistance patterns these isolates to 14 agents reveale...

  Background and Objective: To evaluate extended spectrum betalactamase (ESBL) positive strains of Klebsiella pneumonia and Escherichia coli in positive bacterial cultures. Materials and Methods: In this analytical cross-sectional study, between March 2006 and March 2007, 170 bacterial isolates including 133 cases of E. coli and 37cases of K. pneumonia were...
