Background: The nosocomial infections that cause the establishment of biofilms on the embedded biomedical surfaces are the leading cause of sepsis and are often related to colonization of implants by Staphylococcus epidermidis. Materials and Methods: A total of 40 clinical S. aureus isolates were collected from Zabol, Iran. The ability of these strains to form biofilm was determined by microli...

background: liver fatty acid-binding protein (l-fabp) is the main cytosolic binding site for long chain fatty acids in hepatocytes. fabps enhance the uptake of fatty acids into the cell by increasing their concentration due to decreasing concentration of unbound fatty acids inside the cell. objectives: the aim of this study was to evaluate the effects of dietary unsaturated to saturated fatty a...

Background: The skin of patients with atopic dermatitis has a high susceptibility to staphylococcus aureus (S. aureus) colonization known to produce toxins with super antigen (SAgs) activity which are a family of potent immune-stimulatory exotoxins and may aggravate AD. The aim of this research was to evaluate the ro...

Background: Human brucellosis is a zoonotic disease caused by Brucella melitensis, Brucella abortus, and Brucella suis. Brucella causes a chronic disease, which subverts the immune defense system of their hosts. In this study, the prevalence of an important Brucella virulence determinant, PrpA, which can modulate immune response, was determined in human isolates. Methods: Polymerase chain reac...

Abstract Polyploids with odd-ploidy levels may play an important evolutionary role as they enable backcrosses their parental cytotypes. We chose the ploidy-variable Senecio carniolicus species group to address overarching question if pentaploid individuals, which occur at high frequencies in immediate contact zones of tetraploids and hexaploids, mediate effective interploidy gene flow. employed...

Background: Activity of norA efflux pump is one of the antibiotic resistance mechanisms in ciprofloxacin resistant Staphylococcus aureus. In this study, the effect of Artemisia ciniformis extract on reducing the expression of norA efflux pumps gene in ciprofloxacin-resistant Staphylococcus aureus isolates was studied. Materials and Methods: Ciprofloxacin resistant S. aureus isolates, were trea...
