Background and Objective: Staphylococcus aureus is a major pathogen of human in the world. Methicillin-resistant Staphylococcus aureus is associated with nosocomial infections. Recently, staphylococcal infections have been associated with the community. The purpose of this study was to isolate and identify Staphylococcus aureus virulence Panton-Valentine leukocidin (PVL) and  methicillin...

Abstract As a conserved epigenetic mark, DNA cytosine methylation, at the 5’ position (5-mC), plays important roles in multiple biological processes, including plant immunity. However, involvement of methylation determinants virulence phytopathogenic fungi remains elusive. In this study, we profiled patterns fungus Verticillium dahliae , one major causal pathogens wilt disease that causes great...

Objective: Helicobacter pylori (H. pylori) is a bacterium that infects the gastric mucosa of 50% world population. It known different regional treatment practices used against infections H. affect both expression virulence and antimicrobial resistance genes, giving bacteria geographic differentiation. The aim this study was to perform in silico analysis virulence, genes phylogeny strains obtain...

Introduction: E. coli is the predominant causes of urinary tract infection. Several virulence factors for bacterial infections in the urinary tract are required. In this study, we have considered several virulence factors in strains isolated from the patients with UTI in Yazd. Methods: In this cross-sectional study in 1394-1395, 146 strains isolated were collected from the patients with urinar...

Introduction: In Iran, invasive nontyphoidal Salmonella (iNTS) disease causes severe bacteremic illness among children <5 years old. The global yearly incidence of iNTS disease in children was reported to be in the 3.4 (range&nbsp; 2.1-6.5) million cases,&nbsp; (overall incidence 49 cases (range 30-94) per 100,000 population), the iNTS case-fatality ratio (CFR) of 20% yielded 681,316&nbsp; deat...

background the most common hospital-acquired pathogen is pseudomonas aeruginosa. it is a multidrug resistant bacterium causing systemic infections. objectives the present study was carried out in order to investigate the distribution of virulence factors and antibiotic resistance properties of pseudomonas aeruginosa isolated from various types of hospital infections in iran. patients and method...

Recently, there is an increasing trend in the diversity of pathogenic yeasts isolated from clinical samples. However, Candida albicans is even now the major cause of yeast infections. Candida albicans is one of the members of the mucosal microbiota which can cause cutaneous, mucosal, and disseminated invasive infections in susceptible individuals. For persistence in the host, the yeast must hav...
