Gram positive pathogens mainly Staphylococcus aureus, Enterococcus and Coagulase Negative Staphylococcus are hospital acquired (HA) pathogens. HA strains are usually multidrug resistant (MDR). Monitoring of these strains is essential in order to control their spread in the hospital environment and transmission to the community. The objectives were to assess the prevalence of Gram positive patho...

Food poisoning has been emerged as a worldwide health issue and related illness in both developed and developing countries confirms its significance as an important public health priority.In vitro antibacterialevaluationof nine fluoroquinolone derivatives against food borne bacteria including Gram-positive (Staphylococcus aureus) and Gram-negative (Salmonella enterica, Escherichia coli, Yersini...

Small-colony variants (SCVs) of Staphylococcus aureus cause persistent and relapsing infections. Relatively little is known regarding infections caused by SCVs of coagulase-negative staphylococci. We report two cases of pacemaker electrode infections due to SCVs of Staphylococcus epidermidis and Staphylococcus capitis. Sequence analysis of a portion of the 16S rRNA gene (16S rDNA) confirmed the...

OBJECTIVES To describe the epidemiological, clinical, microbiological characteristics and antimicrobial resistance pattern of Bloodstream infections in Dhahira region, Oman. METHODS Clinical data was collected from all patients with positive blood cultures for two years period. Standard laboratory methods were used for blood culture. Antibiotic sensitivity was tested using Kirby-Bauer disc di...

Coagulase-negative staphylococci (CoNS) have been identified as a major cause of nosocomial infections. Nasal carriage of CoNS in nurses and physicians is known to be an important risk factor for potential hospital infections. This study was carried out to investigate the prevalence of nasal carriage of uncommon coagulase-negative staphylococci among nurse and physician staffs of Tehran Univers...

INTRODUCTION Despite progress in medicine, the prevalence of infective endocarditis (IE) in patients with prosthetic valves (PVE) has not decreased. Positive blood and valve cultures are one of the most important diagnostic criteria of IE. There are no unambiguous data regarding the influence of pathogenic factors on prognosis. AIM To analyse blood and valve cultures in patients with PVE and ...

INTRODUCTION Chronic dacryocystitis results in chronic infection and inflammation of the lacrimal sac. OBJECTIVE To identify the aetiology of chronic dacryocystitis and to determine their antimicrobial susceptibility pattern. MATERIALS AND METHODS A cross - sectional study was undertaken including 120 lacrimal swab materials collected from patients aged above 15 years suffering from chronic...

Staphylococcus caprae, a hemolytic coagulase-negative staphylococcus that is infrequently associated with humans, was initially detected in specimens from six infants in our neonatal intensive care unit due to phenotypic characteristics common to methicillin-resistant Staphylococcus aureus. These isolates were subsequently identified as S. caprae by the Automated RiboPrinter microbial character...

A total of 299 isolates of gram-positive, catalase-positive, coagulase-negative cocci were isolated from a variety of specimens collected from patients at a large university hospital, and 281 (94%) were identified as staphylococci by established methods. Using the scheme of Kloos and Schleifer, we determined the species of the coagulase-negative staphylococci. Staphylococcus epidermidis was the...
