Frequency assessment of β-lactamase enzymes in Escherichia coli and Klebsiella isolates in patients with urinary tract infection
BACKGROUND Production of β-lactamase enzymes is the most common and important mechanism of resistance in Gram-negative bacteria. The objective of this study was to assess frequency of three main β-lactamase enzymes, including extended spectrum β-lactamases (ESBLs), metallo-β-lactamase (MBL), and Klebsiella pneumoniae carbapenemase (KPC) enzymes in Escherichia coli and Klebsiella spp. isolated f...
متن کاملIdentification of extended-spectrum β-lactamase genes in Escherichia coli isolated from patients with urinary tract infection
Introduction: Recentlly, resistance to antibiotics has increased and antibiotic-resistant strains producing extended-spectrum beta-lactamases (ESBLs) have emerged among Enterobacteriaceae, mainly in Escherichia coli (E. coli). In this study we aimed to determine phenotypic and genotypic ESBL production in isolated E. coli from women with urinary tract infection (UTI). Materials and Methods: In...
متن کاملFrequency of fimH, papC, and aer in E. coli Strains Isolated from Patients with Urinary Tract Infection, and their Antibiotic Resistance Pattern
Introduction: E. coli is the predominant causes of urinary tract infection. Several virulence factors for bacterial infections in the urinary tract are required. In this study, we have considered several virulence factors in strains isolated from the patients with UTI in Yazd. Methods: In this cross-sectional study in 1394-1395, 146 strains isolated were collected from the patients with urinar...
متن کاملThe Detection of Fimbrial Pathogenic Genes in E. coli Strains Isolated from Patients with Urinary Tract Infection
Abstract Bachground and objectives: The ability of adherence to the surface of host cell is very critical in the colonization of microbial pathogens. It has been revealed that E. coli strains that infect urinary tracts have different fimbrea such as I, S, FIC, Dr, and fimbrial adhesions. Material and Methods: In this study, 363 urine samples were obtained from patients with urinary tract infect...
متن کاملStudy of Antibiotic Susceptibility Pattern and Frequency of Extended Spectrum β-lactamases Genes TEM and SHV in Urinary Tract Isolates of Escherichia coli and Klebsiella pneumoniae in Tabriz
Background & objectives: Urinary tract infection (UTI) is one of the most common types of human infections and Escherichia coli and Klebsiella pneumonia are the main causes of urinary tract infection among the gram negative bacteria. The prevalence of extended-spectrum β-lactamases (ESBLs) among these bacteria and hence resistant strains to β-lactam antibiotics have increased in recent decades...
متن کاملPrevalence of extended spectrum β-lactamase (ESBL) producing E. coli and Klebsiella species in urinary isolates
Introduction: Bacterial resistance to β-lactam antibiotics has risen dramatically, with extended spectrum βlactamase (ESBL) contributing to this increase. Early identification of ESBL production is becoming increasingly important. Methodology: A total of 367 consecutive, urine samples from patients suspected to have UTI, were processed. All Escherichia coli and Klebsiella species isolated in si...
