background and purpose: actinomycetes have been discovered as source of antifungal compounds that are currently in clinical use. invasive aspergillosis (ia) due to aspergillus fumigatus has been identified as individual drug-resistant aspergillus spp. to be an emerging pathogen opportunities a global scale. this paper described the antifungal activity of one terrestrial actinomycete against the...

objective(s)staphylococcus aureus is a prevalent pathogen worldwide. methicillin resistant s. aureus (mrsa), which is usually multi-resistant in hospitals, has been a daunting challenge for clinicians for more than half a century. the aim of this systematic review and meta-analysis is to determine the relative frequency (rf) of mrsa in different regions of iran.materials and methodssearch terms...

determination of drug resistance rate, as a new major problem in patients with typhoid fever is inevitable for treatment of the disease. in a cross-sectional study, during march 1994 till february 1995, a total of 39 patients with typhoid fever admitted to dept. of infections diseases, emam khomeini hospital, and were examined for the rate of resistance to routine drugs usually used for treatme...

abstract food preservatives are often added to food as preservation method. mostly one preservative alone cannot preserve a product effectively. so it is required to create a preservation system to overcome limitations derived from each preservative. using proper selection of different preservatives may lead to significant practical benefits. in this investigation, resistant strain of bacillus ...

during this research, bacteria resistant to metals were evaluated in the soil of isfahan province.according to the sampling locations the soils are classified as agricultural soils, non-agricultural soils andsediments of the zayanderood riverbank. the bacteria resistant to lead (2 mm), copper (5 mm), cadmium(0.5 mm) and arsenic (5 mm) were identified, and then during later stages, the minimum i...

objectives the study was carried out in a tertiary care center in tehran, iran to identify the frequency of hospital acquired methicillin resistant staphylococcus aureus (ha-mrsa ) colonization and its antibiotic susceptibility pattern and molecular characteristics. patients and methods this point-prevalence study was performed on 631 children who were admitted for at least 48 hours in differen...

multidrug-resistant (mdr) and extensively drug-resistant (xdr) tuberculosis (tb) are increasing globally. treatment options for these patients are very limited. although treatment of these patients with standardized regimen is associated with high mortality and morbidity, rational usage of new drugs might be promising. in this study we will review epidemiology of xdr-tb and tdr-tb in iran and t...

background: candida parapsilosis is an emergent agent of invasive fungal infections. this yeast is one of the five most widespread yeasts concerned in invasive candidiasis. c. parapsilosis stands out as the second most common yeast species isolated from patients with bloodstream infections especially in neonates with catheter. recently several reports suggested that its reduced susceptibility t...

nosocomial infection caused by methicillin-resistant staphylococci poses a serious problem in many countries. the aim of this study was to rapidly and reliably detect methicillin-resistant-staphylococci in order to suggest appropriate therapy. the presence or absence of the methicillin-resistance gene in 115 clinical isolates of staphylococcus aureus and 50 isolates of coagulase negative staphy...
