background one of the most common nasocomial bacteria is methicillin resistant staphylococcus aureus (mrsa). today, herbal extracts like zataria multiflora from the lamiaceae family are increasingly used. objectives in this study, the antibacterial effect of z. multiflora on 75 strains of was evaluated. materials and methods the strains of staphylococcus aureus were examined for isolation of st...

background methicillin-resistant staphylococcus aureus (mrsa) is considered a major cause of nosocomial and community infections. its prevalence varies from country to country, even between hospitals of a country. these bacteria often have multi-resistance and can be difficult to treat. objectives the current study evaluated the effect of hydroalcoholic extract of the stem bark of juglans regia...

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...

objective the extensive pollution of natural ecosystems has occurred by organophosphorus pesticides, being used for improvement of crop production in agriculture. biodegradation is interested in application of multifunctional bacteria containing genetical elements which specially degrade organophosphorus compounds. in this paper the detection of two bacteria species, pseudomonas and flavobacter...

background and objectives: the oprd mutation and ampc overproduction are the main mechanisms of intrinsic resistance to carbapenems such as imipenem and meropenem in pseudomonas aeruginosa . materials and methods: in this study, we investigated intrinsic resistance to carbapenems including mutation of oprd and ampc overproduction in a carbapenem-resistant p. aeruginosa isolated from a burn pati...

background: resistance to anti-tuberculosis (tb) drugs is a global problem. previous studies showed that the prevalence of primary mdr-tb is higher and has been increasing. the purpose of this study was to determine the primary drug resistance in strains isolated from patients with smear-positive of the new cases to anti-tb drugs. methods: in this cross-sectional study, 266 smear positive pulmo...

chemotherapy research highly prioritizes overcoming the multidrug resistance (mdr) in human tumors. liposomal formulation of fluoxetine, as a fourth generation chemosensitizer, was constructed and characterized for percent entrapment, release profile, morphology, particle size, zeta potential and stability. liposomes were prepared using different active loading techniques. the influence of diff...

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...
