bacteremia continues to result in significant morbidity and mortality, particularly among neonates. there is scarce data on neonatal bacteremia in among iranian neonates. in this study, we determined neonatal bacteremia isolates and their antibiotic resistance pattern in neonatal insensitive care unit at beasat hospital, sanandaj, iran. during one year, all neonates admitted to the nicu were ev...

results electron microscopy showed mrsa phages’ resemblance to members of the family siphoviridae, serogroups a and f. they exhibited a latent period of 70 minutes and a relatively burst size of 2,400 plaque-forming units (pfu)/infected cell. the titer of the phages was determined to be 3 × 109 pfu/ml using the by dla technique. conclusions in this study, two phages from the family siphoviridae...

methods in a cross-sectional study, 164 adult patients who were admitted to the icu of a teaching hospital were screened for nasal and extra-nasal carriage of mrsa. in addition, the icu-hospitalized patients were evaluated for mrsa acquisition during their icu stay. results out of the 164 patients admitted to the icu, 12 (7.3%) patients were methicillin-susceptible staphylococcus aureus (mssa) ...

results of total 60 s. aureus isolates, 51 (85%) were mrsa, and of 60 cons, 7 (11.66%) were mrcons. the results showed that the mic of chlorhexidine for all 120 isolates was 1-16 μg/ml. 15 (12.5%) isolates carried qaca/b gene, 26 (21.7%) carried qacc gene, and 38 (31.7%) carried smr gene. conclusions maintenance of mrsa isolates in the attendance of low amounts of antiseptics could result in th...

staphylococcus aureus are important factors for infections that acquired of hospital and community. infections caused by methicillin-resistant staphylococcus aureus mainly of hospital origin, which in many countries is increasing. for this reason, many researchers have tried to find new compounds as a substitute for these antibiotics. hypericin is the active substance h.perforatum and licone ma...

Rapid, high-throughput screening tools are needed to contain the spread of hospital-acquired methicillin (meticillin)-resistant Staphylococcus aureus (MRSA) strains. Most techniques used in current clinical practice still require time-consuming culture for primary isolation of the microbe. We present a new phenotypic assay for MRSA screening. The technique employs a two-photon excited fluoresce...

methicillin-resistant staphylococcus aureus (mrsa) is a major cause of nosocomial infections all around the world. mrsas are usually present in health care centers and hospitals. nowadays methicillin-resistant mrsas in two groups of healthcare associated mrsa (ha_mrsa) and community associated mrsa (ca_mrsa)were studied. predisposing factors for ha_mrsa infections included hemodialysis, surgery...

staphylococcus aureus is an opportunistic pathogen and remains a common cause of burn wound infections. different studies have shown that entrapment of plant-derived compounds into liposomes could increase their anti-staphylococcus aureus activity. silymarin is the bioactive extract from the known plant silybum marianum l. the objective of this study was to evaluate efficacy of silymarin in fre...

nasal mupirocin is found to eradicate effectively methicillin-resistant staphylococcus aureus (mrsa) from colonized patients, but there are concerns about resistant strains. the aim of this study was to detect the mupirocin resistance and nasal carriage of methicillin resistant s. aureus among healthcare workers (hcws) at the university hospitals of tehran.totally 270 nasal swabs were collected...

conclusions similarly to other geographical regions of iran, the sccmec type iii mrsa strain was the most frequently isolated strain from patients in gorgan. staphylococcal cassette chromosome mec type iii showed fewer virulence factors compared to other sccmec types. results the most common sccmec type was type iii, with a frequency rate of 76%, followed by types iv, i, and v, with frequency r...
