High Prevalence of Extended-Spectrum Beta Lactamases among Salmonella enterica Typhimurium Isolates from Pediatric Patients with Diarrhea in China
We investigated the extended-spectrum beta lactamases among 62 Salmonella enterica Typhimurium isolates recovered from children with diarrhea in a Chinese pediatric hospital. A large proportion of S. enterica Typhimurium isolates were resistant to multiple antimicrobial agents, including ampicillin (90.3%), tetracycline (80.6%), trimethoprim/sulfamethoxazole (74.2%), chloramphenicol (66.1%), ce...
متن کاملPrevalence of extended spectrum beta lactamases in Salmonella species isolated from patients with acute gastroenteritis.
INTRODUCTION AND AIMS Extended-spectrum β-lactamases (ESBLs) continue to be a major problem world wide, conferring resistance to the expanded-spectrum cephalosporins. They are increasingly associated with genus Salmonella. This study aimed to determine the prevalence of ESBLs in Salmonella isolates in our region by phenotypic methods. METHODS One thousand stool samples of acute gastroenteriti...
متن کاملPhenotypic and genotypic studies of extended spectrum beta-lactamase (ESBL) resistance among Salmonella isolates from poultry sources in Iran
BACKGROUND: Poultry and poultry products are among the major sources of Salmonella infections for humans. Increasing occurrence of antimicrobial resistance among Salmonellae has become a serious public health concern. The detection of extended spectrum b-lactamase (ESBL) producers among Salmonella spp. has increased in recent years. OBJECTIVES: The purpose of this study was to investigate the a...
متن کاملAntibiotic Resistance Pattern and the Prevalence of Extended Spectrum Beta-Lactamases (ESBLs) in Urinary Isolates of Klebsiella Pneumoniae
Abstract Background and Objective: Klebsiella pneumoniae is an opportunistic nosocomial pathogen causing a variety of infections including urinary tract infections, pneumonia, septicemia, wound infections and infections in the intensive care units. Since the ESBL producing Klebsiella pneumoniae strains are increasingly causing urinary tract infections, we aim to assess antibiotic resistance pat...
متن کاملExtended - spectrum Beta - lactamases
Beta-lactamase enzymes (BLs) have become the most worrisome mediators of antimicrobial resistance expressed by gram-negative bacteria (GNB). The multiple families of BLs have in common the ability to hydrolyze the -lactam rings of one or more members of the penicillins, cephalosporins, cephamycins, carbapenems, and monobactams. Extended-spectrum -lactamases (ESBLs) are a subset of BLs that conf...
