conclusions due to the variable nature of antibiotic susceptibility patterns and etiological agents of septicemia, continual assessment of the most frequent pathogens associated with bloodstream infections and detection of their sensitivity patterns to locally available antibiotics seem to be reasonable measures. results from a total of 491 blood cultures, 74 (15.1%) samples were detected as po...

background: to investigate the prevalence of antibiotic usage in children aged <5 years with acute respiratory tract illness (arti) in iran. materials and methods: data were collected from a national health survey conducted in 2010 (iran’s multiple indicator demographic and health survey). participants of this cross-sectional study were selected by multistage stratifi ed cluster-random sampling...

background: listeria monocytogenes is an important gram-positive disease-causing bacterium existing in milk and dairy products. inhibitory effects of mentha pulegium essential oil at concentrations of 0.03, 0.015, and 0.0075% on growth of l. monocytogenes were studied in iranian white cheese during 60 days of storage. methods: essential oil of m. pulegium plant, collected from north of iran, wa...

background : uncontrolled and irrational use of antibiotics increases the rate of antimicrobial resistance and treatment failure. compliance with antibiotics is an important indicator to show how patients use their prescribed drugs and it can explain the relationship between drug administration and treatment outcome that needs to be monitored and promoted. we decided to evaluate compliance to a...

bacterial sepsis is one of the most common causes of mortality and morbidity in neonates. it has been recognized a gradual change in spectrum of organisms responsible for neonatal sepsis. in this study we have evaluated changing trend of incidence and antibiotic susceptibility in neonatal late - onset sepsis (los) in 2-periods. this study is based on results of blood culture in neonatal late-on...

just regarding different risk factors for antibiotic resistant uropathogenes, it seems justice to improve diagnostic power for drug resistant uropathogenes and well appropriate empirical therapy. 300 and 145 cases of clinicopathologically diagnosed nosocomial and spinal cord injured (sci) associated urinary tract infection (uti), respectively, were considered as our samples included in our 24 m...

background: escherichia coli and staphylococcus aureus as important food-borne pathogens are the main concerns of food producers and consumers which create a lot of problems worldwide. the objective of this study was to investigate the inhibitory effect of monolaurin alone and in combination with edta on viability of e. coli and s. aureus in culture media and iranian white cheese. methods: the ...

Background & Objectives: Nanotechnology is one of great important part of technology. Nanoparticles can be used in different applications for industrial, medical, military and personal use. The objectives of this study were preparation of Polystyrene/ZnO nanocomposite films via a simple method and investigation of antibacterial activity of them. Methods: Polystyrene /ZnO nanoparticle (PS/nano-...

objective: this study investigated the antibacterial properties of an ion-releasing resin composite (degufill), a hybrid resin composite (inten-s), a compomer (compoglass f) and a resin-modified glass ionomer (vitremer) against streptococcus mutans. materials and methods: the bacteria were derived from the dental plaque and cultured on blood agar plates. eppendorf tubes were filled by unset res...

background and aims. triple antibiotic paste (tap) is widely used in endodontics for root canal disinfection, particularly in regenerative procedures. the aim of this in vitro study was to evaluate the antimicrobial effects of different concentrations of tap at 1-, 2-, 3-, and 4-week intervals on mature enterococcus faecalis biofilm. materials and methods. a total of 287 extracted one-rooted hu...
