Background: The aim of this study was to compare the biofilm formation and the prevalence of biofilm-associated genes between the isolates of methicillin-resistant (MRSA) and methicillin-susceptible (MSSA) Staphylococcus aureus. Methods: In total, 209 S. aureus isolates were collected. The antibiotic susceptibility test was conducted using nine antibiotics according to the guidelines of Clinica...

Partial atlE sequencing (atlE nucleotides 2782 to 3114 [atlE(2782-3114)]) was performed in 41 Staphylococcus epidermidis isolates from prosthetic joint infections (PJIs) and 44 isolates from skin as controls. The atlE(2782-3114) allele 1 (type strain sequence) was significantly more frequent in PJI strains (38/41 versus 29/44 in controls; P = 0.0023). Most PJI strains were positive for mecA, ic...
Periprosthetic infection remains a challenging clinical complication. We investigated the antibacterial properties of pure (99.9%) magnesium (Mg) in vitro and in an in vivo rat model of implant-related infection. Mg was highly effective against methicillin-resistant Staphylococcus aureus-induced osteomyelitis and improved new peri-implant bone formation. Bacterial icaA and agr RNAIII transcript...
Clonal dispersion of Acinetobacter baumannii in an intensive care unit designed to patients COVID-19
Introduction: SARS-CoV2 pandemic marks the need to pay attention bacterial pathogens that can complicate hospital stay of patients in intensive care unit (ICU). ESKAPE bacteria which includes Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter cloacae are considered most important, because their close relationship...
BACKGROUND Staphylococcus epidermidis, a member of the human flora, is recognized as an opportunistic pathogen and cause of nosocomial infections. Staphylococcus epidermidis surface components are able to establish bacteria on the host surface, and cause infection. OBJECTIVES The frequency of icaA, IS256, aap, fbe and bhp in clinical isolates of S. epidermidis were investigated in this study....
Coagulase-negative staphylococci (CoNS) are a major cause of sepsis in neonatal intensive care units (NICU) worldwide. Infecting strains of these commensal bacteria may originate from NICU personnel. Therefore, we studied the characteristics of CoNS isolates from NICU personnel and compared them to those of isolates from the general population and from sepsis patients. Furthermore, we studied t...
Background and Objectives: Expression of genes related to biofilm formation in methicillin-resistant staphylococcus aureus (MRSA) can play an effective role in biofilm formation and pathogenicity. Due to the significance of antimicrobial activity of Artemisia species against biofilm producer genes, this study aimed to evaluate the effect of ethanolic extract of Artemisia oliveriana on the...
Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen that causes several nosocomial or community-acquired infections. Adhesion to surfaces and subsequent biofilm formation are the major phases of a staphylococcal infection. The aim of this study was to detect the presence of icaABCD genes in clinical isolates of MRSA. Methods: A total of 110 clinical Staphyl...
