INTRODUCTION Staphylococcus epidermidis strains are frequently associated with catheter-related infection, acute bacteremia, and hospital-acquired infection. Some isolates produce an extracellular matrix called slime that may make them more resistant to antibiotics. The aim of this study was to determine antimicrobial resistance patterns, the prevalence of slime production, and the distribution...

A 25-year-old unmarried man presented with urethral discharge and pain during micturition for the last 2 days. He had had a single unprotected penovaginal sexual encounter with a female sexworker 5 days earlier. He had a history of many heterosexual exposures with multiple partners during the past 5 years, but no history of any previous sexually transmitted diseases. Examination revealed copiou...

introduction: in this study, using the phenotypic and genotypic methods, oxacillin susceptibility in staphylococcus aureus (s. aureus) strains isolated from patients at two government hospitals in ilam, iran was tested. materials and methods: out of 200 s. aureus isolates from different human clinical specimens consisting of blood (31%), wound (20%), urine (21%), catheters (7%), sputum (12%), o...

INTRODUCTION Healthcare waste (HCW) might potentially harbor infective viable microorganisms in sanitary landfills. We investigated the antimicrobial susceptibility patterns and the occurrence of the mecA gene in coagulase-negative Staphylococcus strains (CoNS) recovered from the leachate of the HCW in an untreated sanitary landfill. METHODOLOGY Bacterial identification was performed by physi...

This study was performed with the objective to identify the prevalence of colonization by Staphylococcus aureus in nursing professionals from a teaching hospital in Pernambuco, and evaluate the resistance profile of these isolates. To do this, we performed a cross-sectional study where biological samples were collected from the hands and nasal cavities of the subjects. S. aureus was identified ...

Twenty-four Staphylococcus species or subspecies were examined for their susceptibilities to the fluoroquinolone fleroxacin (Ro 23-6240) by disk diffusion (5-micrograms disk) and by agar dilution for the determination of MICs. Resistant strains were further tested for their susceptibilities to oxacillin and the fluoroquinolone ciprofloxacin. Reference strains of the novobiocin-resistant species...

Purpose: To evaluate the antimicrobial and resistance-reversal activities of seven phenothiazine derivatives against one standard methicillin-sensitive and ten methicillin-resistant Staphylococcus aureus (MRSA) strains originating from human infections. Methods: Minimum inhibitory concentrations (MIC) of the compounds were determined by agar dilution method, and synergy between phenothiazines a...

Coagulase negative Staphylococci (CoNS) are recognized as an important cause of nosocomial infection, especially in neonates and patients with indwelling prosthetic devices. The CoNS resistance rate to oxacillin has been increasing. Therefore, rapid and accurate detection of oxacillin resistance is essential in order to determine the most appropriate antimicrobial therapy. This study aimed to p...

A collection of genetically unrelated vancomycin-resistant enterococci (VRE) including 50 vanA, 15 vanB, 50 vanC1, and 30 vanC2 VRE were used to evaluate the accuracy of eight currently available susceptibility test methods (agar dilution, disk diffusion, E-test, agar screen plate, Vitek GPS-TA and GPS-101, and MicroScan overnight and rapid panels). vanA VRE were detected by all methods. vanB V...

Methicillin resistant Staphylococcus aureus (MRSA) have emerged worldwide and have became resistant to a variety of antibiotics. MRSA colonisation in pigs was first reported in the Netherlands at 2005, where pigs were implicated as a source of human MRSA infections. Dust samples were collected from six large pig farms in Croatia from breeding pig facilities. On each farm, between 5 and 6 sample...
