ABSTRACT Background and Objectives: Several virulence factors are involved in the pathogenesis of Staphylococcus aureus. Surface proteins such as collagen binding proteins (Cna) and fibronectin-binding proteins (FnBP) are important factors in adhesion and invasion of S. aureus. The aim of this study was to evaluate the frequency of adherence genes cna...
We recently described adhesion to and invasion of bovine mammary gland cells by Staphylococcus aureus in vitro. Here, we show that the levels of adhesion and invasion are dependent on the bacterial growth phase and are controlled by the agr locus. Incubation of exponential growth phase cells of S. aureus with mammary gland cells resulted in bacterial cell clumping. Strains of S. aureus deficien...
ABSTRACT The classical neurotransmitter serotonin or 5-hydroxytryptamine (5-HT), synthesized from tryptophan, can be produced both centrally and peripherally. Through binding to functionally distinct receptors, is profoundly implicated in a number of fundamental physiological processes pathogenic conditions. Recently, has been found covalently incorporated into proteins, newly identified post-t...
Plasma fibronectin is a high molecular weight adhesive glycoprotein. There are two types of fibronectin: plasma (soluble) and cellular derived (insoluble). Electron microscopy revealed structural organization compact expanded. In solution, has conformation, after binding to certain substrates (collagen, fibrin, heparin), it one the main opsonins blood in relation “targets” phagocytosis predomin...
Moraxella catarrhalis ubiquitous surface protein (Usp) A1 has been reported to bind fibronectin and is involved in adherence. In this study, using M. catarrhalis mutants derived from clinical isolates, we show that both UspA1 and UspA2 bind fibronectin. Recombinant truncated UspA1/A2 proteins, together with smaller fragments spanning the entire molecule, were tested for binding to fibronectin. ...
conclusions the results of the present study indicate the presence of the pvl and fnb genes in the strains of s. aureus isolated from clinical specimens collected from the patients admitted to teaching hospitals in qazvin. considering the clinical significance of these organisms, and their potential in threatening public health systems, the identification, treatment, and infection control manag...
Invasive lung disease caused by Aspergillus species is a potentially fatal infection in immunocompromised patients. The adhesion of Aspergillus fumigatus conidia to proteins in the basal lamina is thought to be an initial step in the development of invasive aspergillosis. The purpose of this study was to determine the mechanism of adhesion of A. fumigatus conidiospores to basal-lamina proteins ...
