BACKGROUND The treatment of complicated urinary tract infections may require the use of a parenteral antibiotic with potent activity against the most common urinary pathogens. Ertapenem is a broad-spectrum 1beta-methyl carbapenem with a long plasma half-life that allows administration of a single daily dose. METHODS The purpose of this work was to test the in vitro susceptibility to ertapenem...

BACKGROUND Extended-Spectrum Beta-Lactamases (ESBLs)-producing bacteria are increasing challenge in the treatment of both community acquired and nosocomial intra-abdominal infections (IAIs). Investigating the characteristics ofpatients with the IAIs caused by ESBL-producing bacteria and assessing the risk factors of ESBLs infection will lead to appropriate therapeutic management. OBJECTIVE To...

The aims of this study were to investigate drug resistance rates, types of extended spectrum beta lactamases (ESBLs), and molecular epidemiological characteristics of 43 Shigella sonnei isolates. Ampicillin-sulbactam, amoxicillin-clavulanate, chloramphenicol, and ciprofloxacin were the most active antibiotics. Five isolates harbored bla SHV-12, bla(TEM-1) and bla(CTX-M-15). More than 90% of the...

background and objective: nowadays, the presence of extended-spectrum β-lactamases (esbls) producing strains in serratia genus causes the emergence of resistance to many antibiotics. so, the lack of proper diagnosis of esbls strains can lead to failure in the treatment. the objective of the present study was to investigate esbls production in serratia strains isolated from the clinical blood sa...

Background and Objective: Antimicrobial resistance has turned into a key medical and public health crisis globally since the injudicious use of magic bullets (drugs). Aim of this study is focused on the clinical isolate and their percentages of resistant to antibiotics in gram positive bacteria such as MRSA, VRSA, and MSSA are common causes of nosocomical, skin structure infections, bacteremia ...

BACKGROUND Emergence of extended-spectrum beta-lactamases (ESBLs) in Shigella species imparting resistance to third-generation cephalosporins is a growing concern worldwide. The aim of this study is to molecularly characterize the newly emerging beta-lactam resistant Shigella sonnei, specifically ESBLs in Lebanon, and compare them to beta-lactam sensitive isolates. METHODOLOGY We compared fiv...

Objective: Klebsiella pneumoniae is highly prevalent in hospitals and causes many nosocomial infections. The study sought to determine prevalence rates of extended spectrum β-lactamases (ESBLs) in clinical isolates of K. pneumoniae from Cairo, Egypt and to detect the ESBL-encoding genes in the isolates. Methods: K. pneumoniae isolates were collected through two-year period (2011-2012). Identifi...

BACKGROUND & OBJECTIVES Members of the genus Acinetobacter are an important cause of nosocomial infections and with widespread resistance to various antibiotics. Extended spectrum beta lactamase (ESBL) associated resistance among Acinetobacter species is now known. The aim of this study was to speciate clinical isolates of Acinetobacter, analyze their resistance patterns, identify the productio...

BACKGROUND There is a need for new oral agents active against extended-spectrum beta-lactamase (ESBL) producers, as these increasingly cause community-onset infections. We therefore evaluated faropenem, a penem in Phase III development, against recently collected oxyimino-cephalosporin-resistant bacteria. METHODS We tested 847 consecutive cephalosporin-resistant Enterobacteriaceae collected a...

INTRODUCTION Extended-spectrum beta-lactamases (ESBLs) are bacterial enzymes capable of hydrolyzing beta-lactams. The aim of this study was to describe the prevalence of TEM- and SHV-type ESBL-producing Klebsiella pneumoniae strains in Zahedan, Southeast Iran. METHODS A total of 170 non-repetitive K. pneumoniae strains were collected from patients referred to three teaching hospitals of Zahed...
