Background/aim: Staphylococcus aureus colonization is a determiner of disease activation in psoriasis patients. Here we evaluate the presence of genes encoding Panton-Valentine leukocidin (PVL), enterotoxins, TSST-1, exfoliative toxins, and the accessory gene regulatory locus by polymerase chain reaction (PCR) in S. aureus isolates obtained from healthy and diseased skin regions and anterior nares of psoriasis patients and healthy controls. Materials and methods: The presence of PVL and toxin genes was investigated, and agr typing was performed by PCR. Results: Eighteen of the isolated strains carried the sei, 1 carried the seb-sec, and 1 carried the seg1397645907enterotoxin gene. Eight of the …

Background/aim: Virulent Pseudomonas aeruginosa is frequently life-threatening and often challenging to treat, and the emergence of multidrug-resistant isolates presents a critical problem for patients. The aim of the study was concerned with molecular analysis of the virulence factors and antimicrobial resistance profile of multidrug-resistant P. aeruginosa (MDRPA). Materials and methods: Out of 44 MDRPA isolates, 12 isolates representing different resistance profiles and sources of samples were selected for further molecular studies. Polymerase chain reaction (PCR) approaches were applied to identify the genes implicated in antimicrobial resistance or virulence factors in the selected MDRPA isolates. Results: Multidrug-resistance (pstS), ß-lactamase (IMP7, IMP10, …

Background/aim: Sp1 polymorphism of type I collagen genes is accompanied with bone c??ollagen disorders and severe clinical phenotypes such as osteogenesis imperfecta. The aim of this study was to study the association between COLIA1 Sp1 polymorphism and bone density rate. Materials and methods: In this descriptive, analytical study conducted in 2013 in southwestern Iran, 200 blood samples, per the Cochran sample size formula, were taken from women aged 45 and older. DNA was extracted from the samples using the phenol-chloroform method and the genomic fragments in question were proliferated using the polymerase chain reaction (PCR) method. Results: The genotype distribution …
