Background: Community-acquired infections by multidrug-resistant (MDR), extended-spectrum β-lactamase (ESBL) producing Klebsiella species (Klebsiella spp.) is of major concern worldwide. Antibiotic resistance, production of extended-spectrum β-lactamases (ESBLs), and carbapenemases, as well as the presence of classes 1, 2, and 3 integrons in outpatient isolates of Klebsiella collected from Yazd...

Resistance to oxyimino cephalosporins antibiotics in Enterobacteriaceae is primarily done by the extended spectrum β-lactamases (ESBLs). Clear identification of risk factors for ESBL-producing infections is necessary. Therefore, efficient strategies can be developed to decrease outbreak of these infections. The aim of this study was to determine the antibacterial susceptibility and ESBLs patter...

| This study was undertaken to estimate the prevalence and antimicrobial susceptibility of gram negative bacteria (GNB) recovered from dairy cows with subclinical mastitis (SCM) with detection of β-lactamase encoding genes, sulphonamide encoding gene and intergron classes by polymerase chain reaction (PCR). In total, 180 cow’s milk samples were collected from three different dairy farms. Milk s...

UNLABELLED The aim of this study was to determine the prevalence of ESBL-producing Escherichia coli and Klebsiella pneumoniae as well as genes encoding ESBLs. MATERIAL AND METHODS A total of 1207 non-repeat isolates of E. coli and K. pneumoniae were obtained from urine, tracheal aspirate, wound swab and blood from patients hospitalized at the University Clinics in Skopje. ESBL set and E-test ...

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...

This study aimed to assess the frequency of Klebsiella pneumoniae in food samples and to detect antibiotic resistance phenotypes, antimicrobial resistance genes and the molecular subtypes of the recovered isolates. A total of 998 food samples were collected, and 99 (9.9%) K. pneumoniae strains were isolated; the frequencies were 8.2% (4/49) in fresh raw seafood, 13.8% (26/188) in fresh raw chic...
