[ 1 ] - The ability of uropathogenic Escherichia coli isolates in biofilm formation on urinary catheter and association with bcsA and draE genes

The product biofilm by E.coli strain can cause serious problem for human health. Catheter is considered to be s suitable place for colonization of microorganisms, so that in %5-10 of patients who used catheter for only one day and also in all patients who used it for over 28 days, this colonization of bacteria is observed on catheter. This study is come out in order to compare biofilm formation...

[ 2 ] - Lipase Gene Expression of Resistant and Sensitive Candida Albicans to Fluconazole Isolated from Patients Suffering from Oral Candidiasis and Vaginal Candidiasis

Abstract Background and Objective: With the development of drug resistance in strains of fungi, there is a considerable resistance of Candida albicans strains to fluconazole. Molecular studies are developing to determine the relationship of such a drug resistance with the increased gene expression of enzymes produced in drug-resistant Candida isolates. We aimed to evaluate the relationship betw...

[ 3 ] - Antifungal Activity of Soil Chitinolytic Bacilli

Abstract Background and Objective: Chitin, which is a linear polymer of N-acetyl glucosamine residues, has been the most abundant polymer in nature after cellulose. In recent decades, Chitinases have received increased attention because of their wide range of applications, especially in biological control against fungi. Material and Methods: the isolation of bacilli producing chitinolyti...

[ 4 ] - The Prevalenceof Antibiotic Resistance Pattern of Staphylococcus Aureus Isolated from Nasal Carriage of Surgical Ward’s Staff in ShahidrajaeeHospitalofTonekabon,Iran

Abstract Background and Objective:Staphylococcusaureus is one of the important factors causing nosocomial infections. Typically 25-30 percent of healthy people carry the bacteria in their anterior nasal cavity. The physicians(50%), nurses (70%) and hospital staff (90%) are the carriers of this bacteria, leading to the infection of inpatients. The emergence of antibiotic-resistant Staphylococ...

[ 5 ] - Antibacterial effects of Lavandula Stoechas Essential Oil, on Gram Positive and Negative Bacteria
