conclusions the relative higher frequency of some virulence genes in this study may reflect the emergence of isolates containing these genes in shiraz medical centers. background staphylococcus aureus is amongst major human pathogens both in hospitals and the community. this bacterium is an opportunistic pathogen responsible for a large number of self-limiting and even life-threatening diseases...
background staphylococcus aureus is a common cause of infections among humans and animals and it is known as a community-acquired and nosocomial pathogen. most of the isolates contain lysogenic phages which are responsible for production of various virulence factors such as enterotoxins, staphylokinase, β-lysin, lipase, exfoliative toxin a and pantone-vlaentine leukociden (pvl). all staphylococ...
Staphylococcal infections are a group of infections caused by the bacterium Staphylococcus but most infections are caused by a type called Staphylococcus aureus. Bacteria are constantly evolving because their genes are constantly changing. The result of this is that some of the bacteria develop more resistance to a certain antibiotic than others. Methicillin-resistant Staphylococcus aureus is a...
The complete sequence of rpoB, the gene encoding the beta subunit of RNA polymerase was determined for Staphylococcus saccharolyticus, Staphylococcus lugdunensis, S taphylococcus caprae, and Staphylococcus intermedius and partial sequences were obtained for an additional 27 Staphylococcus species. The complete rpoB sequences varied in length from 3,452 to 3,845 bp and had a 36.8 to 39.2% GC con...
OBJECTIVE The aim of this study was to characterize Staphylococcus aureus (MRSA) carriage in a dermatology unit. METHODS This was a prospective and descriptive study. Over the course of 26 weeks, surveillance cultures were collected weekly from the anterior nares and skin of all patients hospitalized in a 20-bed dermatology unit of a tertiary-care hospital. Samples from healthcare workers (HC...
OBJECTIVES Methicillin-resistant Staphylococcus is a growing problem in intensive care units (ICUs). The aim of this study was to describe the epidemiology of methicillin-resistant Staphylococcus isolates in a cardiac surgical ICU over a 5-year period and to determine the risk factors and outcome of this condition. METHODS During the period from January 1998 to July 2003, the clinical data of...
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...
INTRODUCTION Staphylococcus epidermidis is currently the most frequent pathogen of opportunistic and nosocomial infections worldwide. Most cases of Staphylococcus epidermidis infections are associated with indwelling medical devices and/or immunocompromised conditions. Community-acquired urinary tract infections are rare, particularly among pediatric populations, and clinicians often do not con...
Staphylococcus aureus is a major pathogen of varieties of oral mucous infection. Prostaglandin E2 (PGE2) is a pro-inflammatory factor and Cyclooxygenase 2 (COX-2) is a critical enzyme of PGE2 biosynthesis. The purpose of this study is to investigate whether Staphylococcus aureus can increase PGE2 production of oral epithelial cells and how PGE2 functions in the growth and adherence of Staphyloc...
BACKGROUND The burden of methicillin resistant Staphylococcus aureus is a major public health concern worldwide; however the overall epidemiology of multidrug resistant strains is neither coordinated nor harmonized, particularly in developing countries including Ethiopia. Therefore, the aim of this meta-analysis was to assess the burden of methicillin resistant Staphylococcos aureus and its ant...
