objective(s): staphylococcus aureus is an important bacterial pathogen responsible for a variety numbers of nosocomial and community acquired infections. biofilm formation is regarded as an important factor in the establishment of s. aureus infection. the contribution of the genetic background of s. aureus to biofilm formation is poorly understood. the aim of the present work was to genotype s....

a:4:{s:9:"Objective";s:350:"Infertility is one of the major important social issues. Because of the asymptomatic cervical infection, it has caused the problem to remain silent in the majority of patients without diagnosis and treatment. The present study was intended to assess the frequency of Staphylococcus aureus isolated from infertile women's endocervix in northwest Iran.";s:19:"MaterialsAn...

Introduction: Gaseous air pollutants can cause oxidative stress, which can lead to lung damage by inducing inflammation. Polymorphisms in the glutathione S-transferase (GST) gene are involved in the pathogenesis of many diseases, including lung disease. Two glutathione S-transferase Mu 1 (GSTM1) and glutathione S-transferase theta 1 (GSTT1) genes belong to this family, in which deletions occur ...

background protein a is the virulence factors of staphylococcus aureus rolling in its pathogenesis, and its gene is used for typing. polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) with different enzymes has been used for this action. objectives in this study, we used bsp143i enzyme for digestion of the gene, coding protein a (spa gene) in s. aureus. the bacteria w...

conclusions the results revealed, the specific primers that amplified the ente gene were able to amplify the staphylococcal enterotoxin-like toxin type p gene. the specific primers for the entp gene were amplified a fragmented gene (700 bp) showed 100% homology with entp reference gene and also 80% homology with enta and ente genes. results the pcr amplification method was optimized for entp ge...

background staphylococcus aureus is a significant pathogen that can colonize the nares of different animals, causing a wide range of infections in various hosts. objectives we intended to determine the prevalence of s. aureus in the nasal cavity of healthy ruminants and also to investigate the presence of antibiotic resistance genes. materials and methods in the present study, healthy cattle (n...

Staphylococcus aureus is a major causative pathogen of clinical and subclinical mastitis of dairy domestic ruminants. This agent produces a variety of extracellular toxins and virulence factors including Toxic Shock Syndrome Toxin-1 (TSST-1) which is the major cause of Toxic Shock Syndrome (TSS). In this study 58 S. aureus isolates obtained from 9 dairy herds in East and West Azerbaijan provinc...

conclusions hbv in children due to vaccination failure was resulted from vertical transmission. hbv pre-s/s gene mutations were prevalent and could occur before or after vaccination. therefore, simply analyzing mutation frequency of hbv gene was not of value. to advance blocking hbv vertical transmission, future studies should focus on specific mutation sites, potentially associated with vaccin...
