background: the aim of this study was to compare the biofilm formation and the prevalence of biofilm-associated genes between the isolates of methicillin-resistant (mrsa) and methicillin-susceptible (mssa) staphylococcus aureus. methods: in total, 209 s. aureus isolates were collected. the antibiotic susceptibility test was conducted using nine antibiotics according to the guidelines of clinica...

conclusions in the present study, we found a high prevalence of mrsa at the hospitals studied. the findings emphasized the increased prevalence of mrsa isolates containing different toxin and adhesion genes, probably accompanied by antimicrobial resistance. infection with such isolates worsens the clinical outcomes as well as the morbidity and mortality rates in hospitalized patients in icus. m...

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 these findings showed no significant difference regarding the presence of icaadbc genes between blood and wound isolates. background the polysaccharide intercellular adhesion (pia) produced by staphylococcus aureus is effective in the protection of isolates from outer harsh conditions and progress of infection. objectives the aim of this study was to compare the icaabcd genes encodi...

Tigecycline is a new glycylcycline antibiotic structurally similar to minocycline antibiotic. It has broad spectrum activity, including Staphylococcus aureus infections. This is the first study that evaluated the activity of Tigecycline against Staphylococcus aureus isolated from biological samples in Iran. In vitro activity of tigecycline against 160 Staphylococcus aureus including 99 methicil...

background and objectives: methicillin-resistant staphylococcus aureus (mrsa) is a major cause of nosocomial and community acquired infections. detection of mrsa in laboratories is very important for treatment and appropriate infection control. the aim of this study was to evaluate cefoxitin disk diffusion method for detection of mrsa and comparison of this method with other conventional method...

backgroundandobjectives:rapidandaccuratedetectionofmethicillinresistantstaphylococcus aureus (mrsa) is an important role of clinical microbiology laboratories to avoid treatment failure. the aim of this study was to compare conventional methods against the e-test minimum inhibitory concentration (mic) method to determine the best phenotypic method. materials and methods: methicillin resistance...

In The Netherlands a new reservoir of MRSA has recently been identified in pigs and veal calves upon which the 'Dutch Working Party on Infection Prevention' modified the national MRSA guidelines. In June 2006 a new group at risk of MRSA carriage was included, consisting of patients that reported direct exposure to living pigs or veal calves. After the implementation of this modification in a tr...

In the present study, the effectiveness of a rapid and colorimetric nitrate reductase analysis (NRA) method and resazurin microplate assay (REMA) for rapid determination of methicillin resistance among Staphylococcus aureus was investigated. A total of 275 clinical isolates of S. aureus were included in the present study. Among these isolates, 151 had the mecA gene and were resistant to methici...

OBJECTIVE To identify the clinical variables that differentiate MRSA (Methicillin-resistant Staphylococcus aureus) from MSSA (Methicillin-sensitive S. aureus) infection. METHODS Cases having culture isolates of Staphylococcus species were recruited. Baseline and other laboratory parameters were compared between MSSA and MRSA sub-groups to identify the predictors for MRSA. RESULTS Out of 98 ...
