Pasteurella multocida possesses various virulence factors, including capsule, lipopolysaccharide, fimbriae, toxins, outer membrane proteins, and adhesions. Adhesins have a crucial role in mediating colonization and invasion of the host. The aim of the present study was to identify the prevalence of adhesion factor genes and resistance/sensitivity patterns among the avian P. multocida isolates f...

in the development of neuroinflammatory diseases, alterations of the blood brain barrier (bbb) represent key events. the integrity of the bbb is partially maintained by endothelia cells (ecs), since they actively limit the transmigration of immune cells. however, the factors that cause endothelial cells to develop an immune cell-permissive phenotype are poorly understood. in general, it has bee...

background: when provisional restorations are worn for long term period, the adhesion of bacteria becomes a primary factor in the development of periodontal diseases. the aims of this study were to evaluate the surface roughness and bacterial adhesion of four different provisional fixed prosthodontic materials. methods: ten cylindrical specimens were prepared from bis-acrylic composites (previs...

Variations on hydrophobicity were monitored in two marine obligate hydrocarbonoclastic bacteria: Alcanivorax borkumensis SK2T and Thalassolituus oleivoras MIL-1T. These strains were inoculated, separately in ONR7a mineral medium with different concentration of sodium acetate. During 10 days measurements of cellular abundance and cellular hydrophobicity (capacity to adhere at polystyrene) were c...

The ability to adhere to enterocytes is one of the key features of probiotics. This process involves a number of factors, among which the important role of pili was demonstrated. Some Lactobacillus species are confirmed to have heterotrimeric spaCBA type pili. The aim of this study was to identify spaCBA pili in strains of selected Lactobacillus spp. and assess the impact of their presence and ...

the ability of subminimum inhibitory concentrations (sub-mics) of antibiotics to affect the virulence factors of bacteria may be an important criterion in selecting an antibiotic for therapy. proteus mirabilis is one of the most frequently seen pathogens in urinary tract infections. the aim of this study was to analyze the effects of some antibiotics on two important virulence factors of p. mir...

In order to cause endovascular infections and infective endocarditis, bacteria need to be able to adhere to the vessel wall while being exposed to the shear stress of flowing blood. To identify the bacterial and host factors that contribute to vascular adhesion of microorganisms, appropriate models that study these interactions under physiological shear conditions are needed. Here, we describe ...

It has become widely accepted that adhesion receptors can either directly activate, or significantly modulate, many of the signaling cascades initiated by circulating growth factors. An interesting recent development is the realization that adhesion receptors and their cytoskeletal partners can regulate the trafficking of signaling proteins between the cytoplasm and nucleus. Cell adhesion molec...

platelet activation and adhesion to the site of vascular injury is a dynamic process comprising reversible and irreversible phases. platelet adhesion typically occurs in a multi-step process similar to the selectin/integrin-mediated adhesion of neutrophils. this phenomenon is highly regulated and influenced by the cross-talk between platelets and injured endothelium. this cross-talk involves a ...

Adhesion is a critical step in the initial stage of Vibrio alginolyticus infection; therefore, it is important to understand the underlying mechanisms governing the adhesion of V. alginolyticus and determine if environmental factors have any effect. A greater understanding of this process may assist in developing preventive measures for reducing infection. In our previous research, we presented...
