Background & Aims : Aminoglycosides are powerful bactericidal agents used in combination with betalactams or gelicopeptitds, particularly in the treatment of staphylococcal infections. The main objective of this study was to investigate phenotypic and genotypic properties of aminoglycoside resistance in methicillin resistant S. aureus.   Materials & Methods : During 8 months, out of 98 Stap...

Introduction: Urinary tract infection (UTI) caused by E coli is one of the most common diseases in community. Colonization of E. coli and its attachment to the uroepithelium are mediated by adhesions such as P, Fim and S fimbriae. The present study was aimed to evaluate the prevalence of fimbrial virulence genes in Escherichia coli (E. coli) isolates from the patients with urinary tra...

Background & Aims: Helicobacter pylori is a microaerophilic gram negative bacillus which is one of the most common human infections. This bacterium is associated with various diseases and having multiple virulence genes such as toxins and adhesion factors. Several adhesion factors of bacteria involved in binding to the gastric epithelial cell and cause infection. The purposes of this study were...

At the present study in order to detect major genes in a commercial broiler line Bayesian method as the most powerful statistical method in detection of major genes was used. After preliminary data editing, data of body weight (BW) at birth and six weeks of age of 14 and 35 generations respectively were analyzed using iBay software. The results verified segregation of major gene for two economi...

Background and purpose: Spermatogenesis is a well-organized process that is influenced by a variety of factors. Alkaline phosphatase, and Gfra1, Lin28, and Sall4 genes are among the key players in this interconnected process. This study aimed to investigate the expression levels of Gfra1, Lin28, and Sall4 genes in embryonic, spermatogonial, and embryonic stem-like (ES-like) cells in mice. Mate...

Background & Objectives: Escherichia coli is the most common agent of urinary tract infections, with P fimbriae as the most important virulence factor. Uropathogenic Escherichia coli expresses various types of adhesive genes such as P fimbriae and pyelonephritis-associated pili (PAP), which mediate the binding to the surface of epithelial cells in the urinary tract. This study aimed to iden...

Abstract Background and Objective: Escherichia coli O157:H7 is one of the most well-known pathogenic bacteria worldwide that can develop severe diseases such as hemolytic uremic syndrome (HUS). This study aimed to assess the prevalence of virulence genes of E. coli O157:H7 in patients with suspected urinary tract infections (UTIs). Material and Methods: This cross-sectional study was co...
