Staphylococcus aureus is a major bacterial pathogen that causes different community- and hospital-acquired infections. Over time, strains of S. aureus have become resistant to different antibiotics including penicillinase-resistant penicillins. Having data on the local antimicrobial susceptibility pattern of this pathogen is necessary for selection of appropriate...

Methicillin resistant Staphylococcus aureus (MRSA), particularly strains with type III staphylococcal cassette chromosome mec (SCCmec), represent a serious human pathogen in Tehran, Iran. The disease-causing capability depends on their ability to produce a wide variety of virulent factors. The prevalence of exotoxin genes and multiple-locus variable number of tandem repeats fingerprinting (MLVF...

Determination of reliability and construct validity the Persian version Parental Emotional Response to Children Index (P-PERCI) in a sample parents children with ADHD was aim this study. A hundred sixty who had at least six 15 years old living Tehran participated The PERCI addition several socio-demographic items used collect data. results exploratory confirmatory factor analyses showed that fi...

Background: Quinolone resistant Salmonella serotypes have been reported in recent years and become increasingly widespread worldwide. Objectives: We evaluated the molecular mechanism of quinolone resistance non-typhoidal strains isolated from clinical samples Tehran, Iran. Methods: The present study included isolates originated hospitalized individuals outpatients Serotyping nalidixic acid-resi...

We read with interest the recent article by Memon et al. (1). In this study involving the Belgian population, the Helicobacter pylori vacuolating cytotoxin (vacA) genotype was shown to be a strong marker for gastric cancer and duodenal ulcer disease. The finding that certain H. pylori vacA-positive strains are associated with key clinical outcomes is important, but available data are unfortunat...

although more than 3000 antibiotics have been reported from actinomycetes/ higher fungi; biotechnological potential of yeasts and yeast-like fungi with respect to production of antimicrobial compounds has not been sufficiently investigated. we examined the antimicrobial activity of 11 strains of aureobasidium pullulans (two new isolates and nine standard strains). all the strains of aureobasidi...

the lactic acid bacteria (lab) are an industrially important group of probiotic organisms that play an important role in human health by inhibiting harmful and pathogen bacteria growth, boosting immune function, and increasing resistance to infection.  this study aimed to isolate, identify, and biologically characterize probiotic lab strains from iranian traditional dairy products. a total of 2...

background petroleum hydrocarbons are mix compounds and divided into four groups: saturates, aromatics, resins and asphalten. among various phases of crude-oil, the alkanes with medium length chain are favorable substrates that rapidly degraded, although short-chain alkanes are very toxic and long-chain alkanes have low solubility in water that reduce its bioavailability and make resistant to b...

background: fusobacterium necrophorum as a non-spore-forming gram-negative anaerobic bacillus is an important human and animal pathogen. it may cause severe systemic infections (lemierre's syndrome) and some other infections. the aim of this study was to subtype fusobacterium necrophorum by using pcr methods. materials and methods: twenty five strains of fusobacterium necrophorum subspecies fun...

background the importance of sialic acid binding adhesin (saba) as a new outer membrane protein in gastroduodenal diseases has been recognized. the prevalence rate of saba gene varies in different geographic areas. objectives the aim of this study was to determine the frequency of saba gene in helicobacter pylori (h. pylori) strains isolated from different clinical outcomes in tehran, iran. pat...
