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...
Background: Staphylococcus aureus is one of the most common causes of nosocomial infections with high morbidity and mortality rate. Traditionally, methicillin resistant staphylococcus aureus has been considered a major nosocomial pathogen in healthcare facilities, but in the past decade, it has been observed emerging in the community as well. Informations regarding hospital microbial colonizati...
nosocomial infection caused by methicillin-resistant staphylococci poses a serious problem in many countries. the aim of this study was to rapidly and reliably detect methicillin-resistant-staphylococci in order to suggest appropriate therapy. the presence or absence of the methicillin-resistance gene in 115 clinical isolates of staphylococcus aureus and 50 isolates of coagulase negative staphy...
methicillin-resistant staphylococcus aureus (mrsa) is the main cause of hospital infection emerged over the last decades. rapid detection of mrsa is important for patient care and proper usage of infection control. detection of meca genes (encoding resistance to methicillin and other similar antibiotics) and nuc genes (encoding staphylococcal thermostable nuclease) by pcr method is now consider...
conclusions there were diverse phenotypic changes among vancomycin-non-susceptible s. aureus isolates. this may be due to the variety of related regulatory systems. the diversity of phenotypic expression may result in its misidentification in routine laboratory checks. materials and methods a total of 130 methicillin-resistant s. aureus (mrsa) isolates were studied, including 49 vssa, 28 hvisa,...
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 : infections resulted from multi-resistant staphylococcus aureus are increasing worldwide. in the present study, a multiplex-pcr assay for the detection of antibiotic resistance genes among s. aureus clinical isolates and for the concomitant identification of these isolates was described. methods : a total of 127 s. aureus isolates were collected from clinical specimens at three teac...
background and aims: the aim of present study was to investigate the molecular characteristic of staphylococcus aureus to detect mec a gene and to type sccmec in strain isolated from healthy worker at larestan hospital. material and methods: this study was carried out from the 250 nasal swab healthy worker at larestan hospital. multiplex polymerase chain reaction for meca gene was performed in...
background studies revealed that severity of atopic dermatitis correlates with colonization by s.aureus and the density of bacteria and antibiotic resistance is one of the factors in s.aureus recolonization. objectives we aimed to determine the pattern of colonization with different subtypes of s.aureus in patients with atopic dermatitis and its correlation with scorad (scoring atopic dermatiti...
