Sutherland, R. (Beecham Research Laboratories Ltd., Betchworth, Surrey, England), and G. N. Rolinson. Characteristics of methicillin-resistant staphylococci. J. Bacteriol. 87:887-899. 1964.-Cultures of naturally occurring methicillin-resistant staphylococci obtained from a number of hospitals were examined for the nature and degree of resistance to methicillin and other antibiotics. All the cul...
Background: Staphylococci as a micro-organism, has the most importance to cause nosocomial infections, particularly in patients with indwelling catheters or other medical devices. Unfortunately 90% of Staphylococci isolated from the nosocomial infections are resistant to methicillin, and methicillin resistance strains are also resistant to a wide range of antimicrobial drugs, therefore detectin...
There is a growing concern about the application of molecular methods in epidemiological studies of infectious diseases. The objective of this study was to determine the genetic stability of methicillin resistance genes in Staphylococcus aureus for the evaluation of resistance strain distribution. One hundred and fifteen S. aureus isolates from patients with staphylococcal infection were collec...
Background & Objective: Methicillin–Resistant Staphylococcus aureus (MRSA) is one of the most important causes of hospital infections worldwide. Treatment of these infections has become more difficult because of resistance to methicillin/oxacillin and other antibiotics. The aim of this study was to determine the incidence of MRSA infections in hospitals affiliated to Hamadan University of Med...
Introduction: S. aureus, the second most common cause of nosocomial infections, is regarded as an important factor in the severe infections of the community. Methicillin-resistant strains of this bacterium involve a major pathogen which can cause disease and mortality in Iran and the world. Its treatment seems to be difficult due to the prevalence of resistance to most commonly-used antibiotics...
Background and Objective: Methicillin resistance in Staphylococcus aureus is an increasingly important clinical problem. A chromosomal gene, mecA, mediates resistance to penicillinase-resistant penicillins such as methicillin and oxacillin in Staphylococcus aureus. We evaluated the validity of disk diffusion test by using oxacillin, methicillin an...
conclusions the present study showed a high prevalence of aminoglycoside-resistance genes among mrsa isolates in two cities in iran. results the results of drug susceptibility testing showed that the highest rate of resistance was against erythromycin in tehran (84.4%) and gentamicin (71.7%) in sari. all isolates were sensitive to vancomycin, and all strains harbored the meca gene. the aac (6’)...
background: methicillin resistant staphylococcus aureus (mrsa) is one of the major agents for increasing number of serious hospital and community acquired infections. the aim of this study was to investigate the occurrence of the mrsa and meca gene among nosocomial and environmental specimens in kurdistan hospitals and determining the antibiotic resistance of the isolates. materials and methods...
