INTRODUCTION Extended-spectrum beta-lactamases (ESBL)-producing Enterobacteriaceae were first described in relation with hospital-acquired infections. In the 2000s, the epidemiology of ESBL-producing organisms changed as especially ESBL-producing Escherichia coli was increasingly described as an important cause of community-acquired infections, supporting the hypothesis that in more recent year...

The purpose of this study was to investigate the prevalence of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli (ESBL-Ec) in retail chicken meats in Japan. Fifty-six domestic and 50 imported (Brazil, n=36; United States, n=8; Thailand, n=6) chicken meat samples were analyzed. The 162 ESBL-Ec included 111 from 43 (77%) domestic samples and 51 from 26 (52%) Brazilian samples. Fifty...

OBJECTIVE To determine the prevalence of extended spectrum beta-lactamase (ESBL) among multidrug resistant isolates of enterobacteriaceae and non-fermenting gram-negative bacilli. METHODS This study was carried out at the Almana General Hospital, Eastern Province, Kingdom of Saudi Arabia, during the period March 2002 through to June 2003. Multidrug resistant gram-negative isolates from patien...

Objectives Antimicrobial resistant extended-spectrum-β-lactamase-producing Enterobacteriaceae (ESBL-PE) have been shown to be present in healthy communities. This study examined healthy children from the rural Andean village of Llano del Hato, Mérida, Venezuela, who have had little or no antibiotic exposure to determine the prevalence of fecal carriage of ESBL-producing Escherichia coli (ESBL-E...

BACKGROUND & OBJECTIVE Extended spectrum beta-lactamase (ESBL) producing Klebsiella spp led to serious concern about septicaemic neonates in neonatal intensive care units (NICU) due to high resistance against commonly used antimicrobial agents. Knowledge of disease burden and information on resistance to antimicrobials are required for proper management of such cases in NICUs. Here we report th...

Escherichia coli producing extended spectrum beta-lactamase (ESBL) has emerged as a worldwide, public health problem. The aims of this study were to determine the incidence of ESBL-producing E. coli septicemia and evaluate the factors associated with the infection and the clinical outcomes. We reviewed 145 cases of E. coli septicemia among adult patients admitted to Srinagarind University Hospi...

This prospective cohort study was conducted to determine the frequency of infections caused by extended-spectrum beta-lactamase- (ESBL-) producing organisms, various bacteria producing ESBL, antibiotic susceptibility of these organisms, and the risk factors associated with these infections in a neonatal intensive care unit in a tertiary care hospital in North India. Of the 150 neonates enrolled...

BACKGROUND Bloodstream infections (BSIs) caused by enterobacteria remain a leading cause of mortality in patients with chemotherapy-induced neutropenia. The rate and type of colonization and infection with ESBL-producing Enterobacteriaceae (ESBL-E) and their mode of transmission in German cancer centres is largely unknown. METHODS We performed a prospective, observational study at five German...

OBJECTIVE Urinary tract infection (UTI) caused by resistant strains of bacteria is increasingly prevalent in children. The aim of this study was to investigate the clinical characteristics and risk factors for UTI caused by community-acquired extended-spectrum β-lactamase (CA-ESBL)-producing bacteria in infants. METHODS This was a retrospective study performed over 5 years in a single Korean ...

The incidence of nosocomial infection caused by extended-spectrum beta-lactamase (ESBL)-producing bacteria is increasing worldwide. Infections caused by ESBL producers have been associated with severe adverse clinical outcomes that have led to increased mortality, prolonged hospitalization, and rising medical costs. To avoid such adverse events and ineffective treatment, an appropriate use of d...
