Tigecycline is a new glycylcycline antibiotic structurally similar to minocycline antibiotic. It has broad spectrum activity, including Staphylococcus aureus infections. This is the first study that evaluated the activity of Tigecycline against Staphylococcus aureus isolated from biological samples in Iran. In vitro activity of tigecycline against 160 Staphylococcus aureus including 99 methicil...
The emergence of Staphylococcus strains resistant to methicillin occurred shortly after the introduction of methicillin into clinical use . Resistance to methicillin in clinical isolates of Staphylococci has been explained by the production of a characteristic penicillin-binding protein (PBP) , designated PBP2a, that has a decrea...
Staphylococcus epidermidis is the most important member of coagulase negative staphylococci responsible for community and hospital acquired infections. Most clinical isolates of S. epidermidis are resistant to methicillin making these infections difficult to treat. In this study, correlation of methicillin resistance phenotype was compared with methicillin resistance (mecA) gene carriage in 55 ...
discussion our results indicated that agar screening was superior to oxacillin disk agar diffusion. a comparison between the antibiotic sensitivity patterns of the mrcns and the methicillin-susceptible coagulase-negative staphylococci (mscns) showed that the mrcns were predominantly multiple-drug resistant isolates as the simultaneous resistance rate to 4 or more antibiotics in the mrcns and ms...
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 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...
Background and Aim: As one of the major causes of hospital and community acquired infections, Methicillin-resistant Staphylococcus aureus (MRSA) requires accurate and timely diagnosis. This study aimed to investigate the prevalence and antibiotic resistance patterns of MRSA in patients hospitalized in the Birjand-based Imam Reza hospital. Materials and Methods: In this cross-sectional study, a...
The inhibition performances of nafcillin (III), methicillin (II) and penicillin G (I) on the corrosion of copper in HCl was studied and tested by weight loss, Tafel polarization, SEM, UV-vis spectrophotometry, molecular dynamics method and quantum chemical calculations. Polarization curves indicated that the studied inhibitors act as mixed-type inhibitors. The values of inhibition efficiency an...
Background & Objectives: Staphylococcus aureus is one of the most common nosocomial pathogens with high mortality rates. The Biofilm-dependent methicillin-resistant S. aureus remains a major clinical concern in this group of patients. The aim of this study was to investigate the icaABCD forming biofilm genes in methicillin resistant isolates of S. aureus. Materials and Methods: In study was per...
