In this research, for the first time in Iran, Deferoxamine test for differential diagnosis between Staph. epidermidis and Staph. hominis of other gram­positive cocci is introduced. Besides, the comparative results of the susceptibility rates of Staph. aureus (220 Spp.) and Enterococci ( 110 Spp.) to a new glycopeptide antibiotic (SK&Fl04662) and other 12 antibiotics are presented by Disk-Agar D...

conclusions extracts of u. dioica showed significant antibacterial effect against some clinically important pathogenic bacteria. based on the obtained results it can be concluded that u. dioica is useful as antibacterial and bactericidal agent in treating infectious diseases. materials and methods hydroalcoholic extracts from aerial parts were prepared using aqueous solution of ethanol and meth...

Bryophytes are terrestrial plants and they contain many important medical aspects. In this study, six different bryophytes (Polytrichastrum formosum, Plagiomnium cuspidatum, Hypnum jutlandicum, Sphagnum palustre, Rhizomnium punctatum Pellia epiphylla) were collected from Trabzon, Türkiye. The effect of the extract these on some human pathogenic microorganisms especially causing skin diseases (S...

This Staphylococcus epidermidis has been discovered as the most frequent germ detected during indwelling medical devices infection. This fact is well attached with the ability of this bacterium to form structured layered population known as biofilm. Inside S. epidermidis biofilm, bacterial cells present more different behavior than in their planktonic counterpart. This paper describes the thriv...

In the eight-month period of study of all urine samples processed in our routine laboratory, only 85 out of 12 152 specimens yielded a bacteriologically significant growth of either Staphylococcus epidermidis or micrococci. Their growth on MacConkey medium was strictly comparable to that on cysteine lactose electrolyte-deficient (CLED) media. Most micrococci isolated were from urine samples of ...

AIM To assess microbial contamination of 20% autologous serum (AS) eye drops used in a hospital inpatient setting. METHOD 14 patients received autologous serum drops from 4 to 14 days with a cumulative total of 67 days. For each day the first and last drop (total 134 samples) was cultured on broth and blood agar. RESULTS Four patients (9 samples) grew Staphylococcus epidermidis only. One pa...

The aim of this study was to evaluate the effect of oregano essential oil, carvacrol and thymol on biofilm-grown Staphylococcus aureus and Staphylococcus epidermidis strains, as well as the effects of the oils on biofilm formation. For most of the S. aureus (n=6) and S. epidermidis (n=6) strains tested, the biofilm inhibitory concentration (0.125-0.500 %, v/v, for oregano, and 0.031-0.125 %, v/...

The present study was undertaken to evaluate the effect of growth medium on expression of hydrophobicity of Staphylococcus epidermidis. A total of 24 hydrophobic isolates of S. epidermidis, determined by n-hexadecane adherence assay (HAA) earlier were included. Five different growth media: horse blood agar (HBA), brain heart infusion agar (BHIA), brain heart infusion broth (BHIB), tryptic soy b...

OBJECTIVES The skin commensal and opportunistic pathogen Staphylococcus epidermidis is one of the leading causes of nosocomial and biofilm-associated infections, which urgently requires discovery of new antibiotics. We decided to find new leads that target the S. epidermidis tryptophanyl-tRNA synthetase (SeWRS), which is essential for translation. METHODS We applied an approach combining stru...

BACKGROUND Staphylococcus epidermidis (S. epidermidis) has emerged as one of the leading pathogens of biomaterial-related infections. Vascular adhesion protein-1 (VAP-1) is an inflammation-inducible endothelial molecule controlling extravasation of leukocytes. Sialic acid-binding immunoglobulin-like lectin 9 (Siglec-9) is a leukocyte ligand of VAP-1. We hypothesized that (68)Ga-labeled 1,4,7,10...
