INTRODUCTION The present study evaluated biofilm-forming capacity and the presence of both icaA and icaD genes among staphylococcal strains isolated from catheter-related infections and blood culture. METHODOLOGY Ninety staphylococcal isolates, which included 45 strains of catheter infection origin and 45 strains of blood culture origin, were tested for their ability to produce biofilm using ...

The International Symposium of Staphylococci and Staphylococcal Infections is a biennial conference that brings together clinicians who treat staphylococcal infections in the community and in hospitals, veterinary microbiologists who study staphylococcal infections in animals, and basic scientists who study pathogenesis of infection and the biology of staphylococci. Over 430 delegates from 24 c...

The nosocomial infection rate within the study period (January 1 December 31, 2010) was highest during January and lowest during December, while it was highest during May and August and lowest during January in 2011. The investigated 170 specimens for nosocomial infection showed that 51.7 and 48.3% had community-acquired and nosocomial infection, respectively. Nosocomial infection included resp...

Introduction Polymyositis and dermatomyositis may be asscciated with autoimmune phenomena and with malignancy. The initiating factors are unclear; viral infections have been proposed (Pearson and Bohan, 1977) and a few cases have been associated with bacterial and parasitic infections (Naidoo and Chan, 1975; Kegen, Kimball and Christian, 1974; Greenlee et al., 1975; Samuels and Rietschel, 1976)...

Staphylococcus aureus frequently causes community- and hospital-acquired infections. S. attachment followed by biofilm formation on tissues medical devices plays a significant role in the establishment of chronic Staphylococcal biofilms encase bacteria matrix protect cells from antimicrobials immune system, resulting infections that are highly resistant to treatment. The biology is complex vari...

Staphylococci and streptococci are leading causes of healthcare community-acquired bacterial infections worldwide. Within each genus, virulent species such as Staphylococcus aureus, Streptococcus pyogenes pneumoniae associated with diverse syndromes superficial infection, invasive infection exotoxin production. less coagulase-negative staphylococci viridans common harmless human commensals but ...

BACKGROUND Studies and guidelines recommending the retention of the central venous catheter (CVC) in patients with coagulase-negative staphylococcal bacteremia were based on loose definitions of bacteremia and/or did not evaluate the risk of recurrence. In this study, we used strict definitions of coagulase-negative staphylococcal bacteremia to determine the impact of CVC retention on response ...

Staphylococcus aureus remains a common cause of nosocomial bacterial infections and are often antibiotic resistant. The role of NK cells and IL-15 and their relationship in host defense against extracellular bacterial pathogens including S. aureus remain unclear. We have undertaken several approaches to address this issue using wild type (WT), IL-15 gene knock-out (KO), and NK cell-depleted mou...

BACKGROUND S. aureus acquires heme-iron using the iron regulated surface determinant (Isd) system and the heme transport system (Hts) with both systems showing critical importance in systemic models of infection. The contribution of heme-iron acquisition to staphylococcal pneumonia has not yet been elucidated. In addition, the use of computed tomography (CT) for the evaluation of staphylococcal...
