“…There was also a correlation between the degree of proteolysis of surface proteins and the reduction in adherence as demonstrated by the immunoblot and adherence assays when comparing trypsinized and proteinase K-treated cells. In previous studies of bacterial adherence to inanimate and mucosal surfaces, components on the surface of bacterial cells have been shown to be important in determining their ability to adhere (24,(26)(27)(28)(29)(30)(31). The presence of pili on gonococci correlates with adherence and with pathogenicity.…”

“…Multiple adhesive mechanisms would require the target or target tissue to display more than one type of receptor (serum or blood components) before optimal adhesion can be achieved. These requirements also minimize the chances of coincidental attachment to nontargeted areas (27). Thus, the attachment of a TSS strain to fibers through blood and serum components would seem to be more specific than that of fiber alone.…”

To study the role of surface proteins in the adherence ofStaphylococcus aureus to fibers that are used in tampon and surgical gauze pad manufacture, we have developed an adherence assay with S. aureus cells and cotton and rayon fibers. Results suggest that staphylococcal adherence is dependent on both the substrate and the material used to coat these fibers. Scanning electron micrographs supported the adherence results and revealed more cells on the surface of cotton than rayon fibers.Treatment of staphylococcal cells with proteolytic enzymes significantly reduced binding to pure cotton and detergenttreated cotton fibers. Immunoblot analysis of cell wall proteins suggested that surface proteins in the mol wt range of 120-220 kD were involved in the adherence of S. aureus to cotton fibers. Although the adherence of S. aureus to cotton fibers alone appeared to be mediated through surface charge or hydrophobic interactions, bacterial binding to fibers which have been pretreated with defibrinated blood appeared to be more specific and independent of the surface constituents of the fibers. The results of these studies implicate staphylococcal surface proteins in the adherence of S. aureus to commercially available tampon fibers and surgical gauze pads.

“…Specific colonisation mechanisms can be advantageous to the participants in a host-(or tissue-) pathogen relationship. Colonisation by a particular bacterial species may vary considerably according to the host species and tissue (Christensen et al, 1985) These conditions are known as host tropism and tissue tropism respectively. Extracellular protease and elastase may play an important role in establishing these host and tissue tropisms.…”

Age-dependent changes in protease and elastase production in cultures of Pseudomonas aeruginosa

Summary. The intracellular and extracellular protease and elastase contents of Pseudomonas aeruginosa were studied in relation to the age of the culture. The intracellular protease and elastase content of the organisms decreased as the culture grew older, whereas extracellular protease and elastase greatly increased 24 h after incubation commenced, suggesting that host tissue injury by P . aeruginosa infection may increase in proportion to the duration of tissue colonisation.

“…The biologically and chemically synthesized silver nanoparticles were added to the bacterial suspensions in the appropriate volume 15 µl of AgNPs to 105 µl of bacterial culture and incubated 72h at 22°C. The biofilm amount in a 96-well plate was quantified by crystal violet (CV) staining according to the method by Christensen et al [8] with some modifications. The concentration of CV was determined by measuring the optical density of solution at 620 nm using a microtiter plate reader.…”

The effect of biologically and chemically synthesized silver nanoparticles (AgNPs) on biofilm formation

et al. 2017

Abstract. Bionanotechnology has emerged up as integration between biotechnology and nanotechnology for developing biosynthetic and environmental-friendly technology for synthesis of nanomaterials. Different types of nanomaterials like copper, zinc, titanium, magnesium, gold, and silver have applied in the various industries but silver nanoparticles have proved to be most effective against bacteria, viruses and eukaryotic microorganisms. The antimicrobial property of silver nanoparticles are widely known. Due to strong antibacterial property silver nanoparticles are used, e.g. in clothing, food industry, sunscreens, cosmetics and many household and environmental appliances. The aim of the study was to compare the effect of silver nanoparticles (AgNPs) synthesized biologically and chemically on the biofilm formation. The biofilm was formed by the bacteria isolated from the water supply network. The commonly used crystal violet assay (CV) was applied for biofilm analysis. In this study effect of biologically synthesized Ag-NPs on the biofilm formation was evaluated.
