results a number of 7-11 repeats in the spa gene xr region were determined. strains with 10 repeats were65%, therefore they had the highest percentage in isolates. seven repeats strains were 20% and each of the strains with 8, 9 and 11 repeats had the frequency of 5%. s. aureus strains antibiotic resistance was 35%, 5%, 45% and 40% for tetracycline, amoxicillin, gentamicin and erythromycin resp...

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....

Abstract Tuberculosis and diabetes mellitus are the most important reasons in mortality all over the world. It’s clear that reviewing of relationship between Tuberculosis (TB) and diabetes mellitus (DM) is necessary; on the other hand it’s found that FTO gene has the positive relationship with metabolic issues. Therefore, it’s necessary pay attention to the above and danger...

Coagulase-negative staphylococci (CoNS) are often associated with bovine mastitis and may be resistant to antimicrobial therapy. The aim of the current study was to investigate the presence of blaZ (responsible for penicillin resistance) and mecA (responsible for methicillin resistance) genes among 108 CoNS belonging to 9 different species isolated from bovine mastitis in seven dairy herds (H1-...

Background and Aim: Pseudomonas aeruginosa is an important ubiquitous and especially common pathogen in the hospital. Exotoxin A that encoded by exoA gene has a role in pathogenesis of this bacterium. Today, probiotics are widely used in the treatment and prevention of diseases. The present study aimed to study the Saccharomyces cerevisiae S3 effect on the expression of exoA gene. Materials an...

a:4:{s:10:"Background";s:897:"Human luteinizing hormone (hLH) belongs to glycoprotein hormones which is composed of two non-covalently linked subunit, α and β. The α-subunit is similar in all glycoprotein hormones, whereas the β-subunit is conferring the hormonal specificity. This hormone has important roles in the growth and maturity of sexual organs and secondary sexual characteristics and st...

Sergentomyia sintoni is the natural vector of Sauroleishmania species of lizards. This sandfly isabundance in and around the burrows of great gerbils. S. sintoni was collected from peridomestic animalshelters, inside and around houses and also from the nearby burrows of the gerbil reservoir hosts,Rhombomys opimus, in several provinces of Iran. Mitochondrial Cytochrome b (Cyt b) of sandflies, wh...

the clar of streptomyces clavuligerus in the clavulanic acid gene cluster encodes a transcriptional regulator that controls clavulanic acid biosynthesis. the main goal of this study was isolation and molecular detection of the clar gene and its cloning in the streptomyces specific vector (pma:: hyg). by cinsideration of the clar gene’s start codon, the specific primers were designed. after geno...

objective(s) the mitochondrial defects in friedreich's ataxia have been reported in many researches. mitochondrial dna is one of the candidates for defects in mitochondrion, and complex i is the first and one of the largest catalytic complexes of oxidative phosphorylation (oxphos) system. materials and methods we searched the mitochondrial nd4l gene for mutations by ttge and sequencing on ...
