Background and Objective: Vancomycin-resistant enterococci (VRE) are the major causative agents of urinary tract infections (UTIs) in hospitalized patients. The aim of this study was to determine the prevalence of urinary tract infections caused by enterococcus faecium and the level of resistance to vancomycine and other antibiotics which are effective in enterococcal infection therapy of hospi...
BACKGROUND Early identification of pathogens and antimicrobial resistance in bloodstream infections (BSIs) decreases morbidity and mortality, particularly in immunocompromised patients. The aim of the present study was to compare real-time polymerase chain reaction (PCR) with commercial kits for detection of 17 pathogens from blood culture (BC) and 10 antimicrobial resistance genes. METHODS A...
18 19 The aim of this study was to develop a method for detecting antibiotic resistance 20 (AR) genes in cheese based on a combination of multiplex PCR and a DNA microarray 21 hybridisation system. Twenty oligonucleotide probes were designed targeting 10 22 common AR genes, namely aac(6’)-Ie-aph(2’’)-Ia, aadE, aphA-3, ermB, tet(L), tet(M), 23 tet(O), tet(S), vanA and vanB. Specificity of the pr...
VanD-type resistance to glycopeptides in Enterococcus faecium BM4339 is due to constitutive synthesis of D-alanyl-D-lactate-terminating peptidoglycan precursors (B. Périchon, P. Reynolds, and P. Courvalin, Antimicrob. Agents Chemother. 41:2016-2018, 1997). The sequence of a 5,780-bp fragment was determined and revealed six open reading frames. The 3' distal part encoded the VanHD dehydrogenase,...
OBJECTIVE The objective of the study was to investigate the prevalence of vancomycin-resistant Staphylococcus aureus (VRSA). MATERIALS AND METHODS Three hundred and fifty-six S. aureus isolates from the Imam Khomeini hospital in Tehran, Iran, were evaluated for methicillin and decreased vancomycin susceptibility by the microbroth dilution method. The mecA, vanAand vanB genes were targeted by ...
Background: Enterococci are intrinsically resistant/tolerant to various antimicrobial agents and can also acquire combine different mechanisms of resistance, including quorum-sensing regulation, most active compounds, which makes enterococcal infection treatment even more challenging. The aim this study was evaluate the pattern resistance analyze frequency asa1 esp genes in clinical isolates re...
