Background and Objectives: The presence of ESBLs (Extended spectrum β-lactamase) for the health system has many problems. Moreover, these strains have increased resistance to other antibiotics.The aim of this study was to determine the molecular detection of blaTEM, blaCTX and blaSHV beta-lactamase genes in Bacillus subtilis strains isolated from raw milk and cheese samples. Materials and Meth...
Extended-spectrum-beta-lactamase (ESBL)-producing organisms have captured the attention of clinicians and laboratorians and are agents of nosocomial and community onset infections (J. D. Pitout and K. B. Laupland, Lancet Infect. Dis. 8:159-166, 2008). ESBLs in many enterobacteriaceae and in nonfermenting Gram-negative organisms have been described (K. Bush and G. A. Jacoby, Antimicrob. Agents C...
BACKGROUND AND PURPOSE In addition to beta-lactamase production, loss of porins confers resistance to extended-spectrum beta-lactams in Klebsiella pneumoniae and Escherichia coli infection. This study describes the detection of SHV-12 extended-spectrum beta-lactamase (ESBL) subtype and the loss of OmpK35 porin in 4 strains of K. pneumoniae and E. coli. METHODS Isoelectric focusing was perform...
Multidrug-resistant Pseudomonas aeruginosa nosocomial infections are increasingly recognized worldwide. The existence of metallo-beta-lactamase- and extended-spectrum beta-lactamase-producing isolates exhibiting resistance to most beta-lactam antimicrobial agents greatly complicates the clinical management of patients infected with such isolates. Since 1998, P. aeruginosa isolates resistant to ...
background klebsiella pneumoniae is a family member of enterobacteriaceae. isolates of k. pneumoniae produce enzymes that cause decomposition of third generation cephalosporins. these enzymes are known as extended-spectrum beta-lactamase (esbl). resistance of k. pneumoniae to beta-lactamase antibiotics is commonly mediated by beta-lactamase genes. objectives the aim of this study was to identif...
Pseudomonas aeruginosa is an opportunistic pathogen which is naturally resistant to a large range of antibiotics like lots of Beta–Lactams (penicillins, cephalosporins and carbapenems) and may cause additional resistance after unsuccessful treatment. The understanding of beta-lactamase identification and detection in these bacteria is very valuable. In recent years a number of variety of new be...
