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 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...

The worldwide emergence of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) can have severe public health implications. Familial transmissions of CA-MRSA in The Netherlands were investigated. Among the families studied, two clusters of CA-MRSA could be identified. This report demonstrates that family members can serve as reservoirs of CA-MRSA which may become a serious p...

conclusions we report a high methicillin-resistant s. aureus rate in our hospital. additionally, t030 and t037 were the predominant spa-types among hospital-associated s. aureus. our findings emphasize the need for continuous surveillance to prevent the dissemination of multidrug resistance among different s. aureus protein a types in iran. background the incidence of nosocomial staphylococcus ...

conclusions our results illustrated the presence of clonal groups of highly gentamicin-resistant strains of mrsa in hospitals in tehran. the php typing method provided useful information for both clonal dissemination and determining the epidemiological links of the clonal groups of the mrsa strains. materials and methods a total of 301 s. aureus isolates were collected during january to novembe...

background hospital patients who are nasal carriers of methicillin-resistant staphylococcus aureus (mrsa) are a high-risk potential threat to themselves and other hospitalized patients. the high antibiotic resistance of these isolates renders the treatment of related infections difficult. objectives the present study, for the first time investigated the prevalence of mrsa isolates in nasal carr...

objective(s)staphylococcus aureus is a prevalent pathogen worldwide. methicillin resistant s. aureus (mrsa), which is usually multi-resistant in hospitals, has been a daunting challenge for clinicians for more than half a century. the aim of this systematic review and meta-analysis is to determine the relative frequency (rf) of mrsa in different regions of iran.materials and methodssearch terms...

objectives the study was carried out in a tertiary care center in tehran, iran to identify the frequency of hospital acquired methicillin resistant staphylococcus aureus (ha-mrsa ) colonization and its antibiotic susceptibility pattern and molecular characteristics. patients and methods this point-prevalence study was performed on 631 children who were admitted for at least 48 hours in differen...
