results out of 238 samples, 5.88% were resistant to quinupristin-dalfopristin; 5.46% to linezolid; 60.92% to co-trimoxazole; 31.93% to doxycycline; 18.90% to tigecycline; 5.04% to vancomycin; 9.24% to mupirocin; 43% to oxacillin and 46.21% of our isolates were resistant to cefoxitin. conclusions coming across isolates with reduced susceptibility to quinupristin-dalfopristin and resistant to lin...

introduction: thyroid gland is well known to resist infections by rich blood supply and lymphatic drainage,   high glandular content of iodine which can be bactericidal and separation of the gland from other structures of neck. primary thyroid abscess resulting from acute suppurative thyroiditis (ast) is an unusual type of head and neck infection and it is a rare condotion in children so that p...

background staphylococcus aureus is a major nosocomial pathogen world wide. mupirocin plays a crucial role in strategies designed to control outbreaks of s. aureus. objectives the aim of this study was to determine the frequency of mupirocin resistance in s. aureus strains isolated from nasal carriers among the hospitalized patients at kermanshah hospital, iran. patients and methods a total of ...

background: methicillin-resistant staphylococcus aureus (mrsa) is resistant to most antibiotics and is an important pathogen of nosocomial infections. the prevalence of community (ca-mrsa) and hospital acquired methicillin-resistant s. aureus (ha-mrsa) infection is increased. in this study we investigated the frequency of mrsa colonization and its antibiotic susceptibility in students of rafsan...

background coagulase-negative staphylococci (cons) are opportunistic pathogens. methicillin resistance is common in cons and may play an important role as reservoir of staphylococcal cassette chromosome mec (sccmec) for staphylococcus aureus. objectives the aim of this study was to determine molecular characteristics of nasal carriage of methicillin-resistant coagulase negative staphylococci am...

conclusions since it is highly important to rapidly detect mrsa isolates, especially in nosocomial infections, phenotypic methods may certainly be useful for this purpose. resistance to methicillin in s. aureus shows a substantially increased ability in turanose metabolism. it is concluded that fermentation of turanose at 0.7% dilution could be a rapid detection method for primary screening of ...

background staphylococcus aureus is associated with different infections ranging from skin and soft tissue infections to endocarditis and fatal pneumonia. s. aureus is still the most common bacterial species isolated from inpatient specimens and the second most common from outpatient specimens. today, methicillin resistant s. aureus (mrsa) isolates are present in the hospitals of most countries...

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...

materials and methods this definitive and cross-sectional study was conducted in tehran, iran. a total of 15 s. aureus isolates were collected from wound samples with sterile swabs and were identified by the conventional diagnostic tests. the antibiotic susceptibility pattern was performed according to the clinical and laboratory standards institute (clsi, 2012) protocol. the meca gene, staphyl...

b a ckground : in fact the biofilms are composed of bacterial cells living inmulticellular structures such as tissues and organs embedded within a self-produced matrix of extracellular polymeric substance (eps). ability to attach and biofilm formation are the most important virulence factors staphylococcus aureus isolates. the aims of this study were to detect intracellular adhesion (ica) locus...
