background : the emergence and increase in the incidence of extended-spectrum beta lactamase (esbl) producing escherichia coli has become an emerging challenge especially in hospitalized patients with uti. the aim of the present study was to survey the frequency of bla ctx-m genotype in esbl producing e. coli isolated from hospitalized patients with uti and determination of their antibiotic res...

background and objective: organisms producing ctx-m β-lactamases are emerging as a source of resistance to oxyiminocefalosporins such as ceftriaxone and ceftazidime. however, the laboratory detection of these strains is not well defined. in this study, phenotypic assay for screening of extended-spectrum β-lactamases producing strains and molecular assay for the identification of ctx-m β-lactama...

The purpose of the study was to examine prevalence Escherichia coli in shrimps and mussels, determine distribution β-lactam, aminoglycoside, quinolone, multi-drug resistance phenotypically genotypically E. isolates obtained from mussels Istanbul. Faecal samples were collected (n = 96) Marmara Sea coastline fish markets For detection antibiotic susceptibilities, seven groups used. β-lactam...

conclusions this study was the first report of the emergence of the plasmid-encoded blaoxa genes among e. cloacae isolates in iran. these findings highlight the need to use appropriate infection control policy and rational antibiotic therapy to reduce further spread of these resistant bacteria in the studied hospitals. results in total, 48 esbl-producing isolates (58.5%) were positive for the b...

OBJECTIVES To determine the prevalence of class A extended spectrum β-lactamases (ESBL)-producing Escherichia coli and Klebsiella spp., and to investigate clonality among ESBL-producing isolates of nosocomial and community infections. METHODS The study involved 354 nosocomial infections samples and 992 community infections samples, obtained between 2003 and 2006 at Caxias do Sul, RS. The dete...

OBJECTIVES To determine the prevalence and types of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli occurring in pigs at slaughter in the UK in 2013. METHODS Caecal samples from 637 pigs, sampled via a UK-wide monitoring programme in 2013, were enriched overnight in buffered peptone water, before plating to CHROMagar CTX and Oxoid Brilliance ESBL agar. Presumptive ESBL-produci...

OBJECTIVES To assess the in vitro susceptibility of multidrug-resistant Enterobacteriaceae (MDRE) isolates to tigecycline. METHODS Clinical isolates of MDRE tested in this study were obtained from 91 hospitals in Belgium during the period January 2010 to April 2010. MICs of tigecycline were determined by Vitek 2 (VTK) and by the reference broth microdilution (BMD) method, and the results were...

Background and Aim: Escherichia coli causes a bacterial illness that frequently affects cats. Diseases caused by E. are treated using antibiotics. Because of their proximity to humans, cats possess an extremely high risk contracting antibiotic resistance genes when owners touch cat feces containing harbor genes. This study was conducted identify multidrug-resistant extended-spectrum β-lactamase...

Reports of ESBL (extended spectrum β-lactamase) producing E. coli strain in UTI (urinary tract infections) patients is increasing. This study determines the presence of ESBL in E. coli isolates from UTI patients. A total of 414 cultured urine samples were collected from hospital. E. coli was isolated from these cultures using conventional microbiological tools. These antibiotics of third genera...
