Objective: To analyze the clinical and economic impact of community-onset urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae requiring hospitalization. Methods: A retrospective cohort study that included all adults with a UTI K. were admitted to tertiary care hospital in Barcelona, Spain, between 2011 2015. Demographic, clinical, da...

Objective(s) Extended-spectrum beta-lactamase (ESBL) producing bacteria have an important role in nosocomial infections. Due to the limited availability of information about the molecular epidemiology of ESBL producing bacteria in Mashhad, we decided to investigate about TEM, CTX and SHV ESBLs among urinary Escherichia coli isolates in Mashhad, a city in northeast Iran. Materials and Methods ...

Food contamination with extended-spectrum beta-lactamase (ESBL)-producing bacteria is recognized as one of the public health concerns worldwide. Although fish and fishery products at retail in Japan have relied on imported materials, no apparent evidences exist prevalence property genetic transfer ESBL-producing those food specimens. This study aimed to investigate plasmid-mediated antibiotic-r...

Background and Objectives: Antimicrobial agent use in pisciculture exerts a selective pressure, resulting reservoirs of extended spectrum beta-lactamase producing Escherichia coli the aquatic environment. Here we screened fish parts as non-clinical source CTX-M TEM Extended Spectrum Beta-lactamases (ESBL) Southeastern Nigeria Methodology: A total sixty [fish gills, body part intestinal swab sam...

Among 235 extended-spectrum beta-lactamase-producing Klebsiella pneumoniae (ESBL) isolates collected from a nationwide surveillance performed in Taiwan, 102 (43.4%) were resistant to amikacin. Ninety-two of these 102 (90.2%) isolates were carrying CTX-M-type beta-lactamases individually or concomitantly with SHV-type or CMY-2 beta-lactamases. The armA and rmtB alleles were individually detected...

We performed extended-spectrum beta-lactamase (ESBL) phenotypic testing and molecular characterization of three ESBL genes (TEM, SHV and CTX-M) and susceptibility testing by Clinical Laboratory Standards Institute (CLSI) disk diffusion method against three cephalosporins (ceftriaxone, ceftazidime, cefepime) and a cephamycin (cefoxitin) among 128 Thai Escherichia coli and 84 Thai Klebsiella pneu...

Proteus mirabilis is a specific opportunistic pathogen of many infections including urinary tract (UTIs). Risk factors are linked with the acquisition multidrug-resistant (MDR) to 3 or more classes antimicrobials) strains. The resistance in extended-spectrum alpha-lactamase rare, but rising beta-lactamase (ESBL) producing strains matter concern. ?-lactamases and antibiotic modifying enzymes mai...
