BACKGROUND The aim of this study was to investigate the antibiotic susceptibility pattern as well as the phenotypic and genotypic biofilm formation ability of Staphylococcus aureus isolates from patients with urinary tract infection (UTI). METHODS A total of 39 isolates of S. aureus were collected from patients with UTI. The antibiotic susceptibility patterns of the isolates were determined b...

conclusions the remarkable rates of biofilm production ability among clinically isolated staphylococci emphasize the necessity of more effective infections control policies to prevent biofilm formation on medical devices and hospital environmental surfaces. background biofilm formation capacity is recognized as an important virulence factor in staphylococci that makes the organisms more resista...

The aim of this study was to investigate the presence of virulence genes in 46 coagulase-negative staphylococci (CNS) strains isolated from 46 udder quarters of 46 cows with subclinical mastitis. The isolates were examined phenotypically (cultural features, Gram stain, catalase, coagulase, API tests) and genotypically for: icaA, icaAB, icaD, atlE, bhp, agrA, sarA, mecA, and blaZ genes. These is...

The objective of this study was to evaluate the effects of NaCl on the biofilm formations of the isolate from Staphylococcus aureus outbreaks linked to ham. The S. aureus ATCC13565 isolated from ham was exposed to NaCl concentrations of 0%, 2%, 4%, and 6% supplemented in tryptic soy broth (TSB) for 24 h at 35℃, followed by plating 0.1 mL of the culture on tryptic soy agar containing 0%, 2%, 4%,...

Background: The nosocomial infections that cause the establishment of biofilms on the embedded biomedical surfaces are the leading cause of sepsis and are often related to colonization of implants by Staphylococcus epidermidis. Materials and Methods: A total of 40 clinical S. aureus isolates were collected from Zabol, Iran. The ability of these strains to form biofilm was determined by microli...

The prevalence of Staphylococcus aureus (S. aureus) among patients with urinary tract infections (UTIs) has become a significant cause morbidity in all age groups. aim the current study was to identify S. methicillin-resistant (MRSA). Moreover, it aimed determine their antimicrobial susceptibility patterns and detect presence mecA, lukPV icaA genes isolated UTIs patients. A total 402 urine samp...

introduction: biofilm producing staphylococcus aureus is known as one of the major causative agents of infections, failure of implanted devices and persistent infection among hospitalized patients . the aim of the present study was to determine the frequency of biofilm producing s. aureus isolates amongst the clinical specimens. methods: this cross-sectional study was conducted during 2012 to 2...
