Blood-borne bacteria

There is evidence that lipid emulsion, which is cleared by the Kupffer cells of the reticuloendothelial system, can adversely affect reticuloendothelial function by reducing its ability to remove blood-borne bacteria. In a study of the blood clearance and organ localization of viable S-radiolabelled Escherichia coli after slow intraperito-neal and more rapid intravenous administration of 20% fat emulsion in Sprague-Dawley rats, although there was...

Polymers can also be used to prevent the adsorption of proteins to surfaces. For example, polyvinylpyrrolidone can prevent protein adsorbing onto a variety of surfaces and it can also displace adsorbed protein [ 18]. This has led, for example, to its application in the coating of filtration membranes in order to reduce biofouling. Polymers are also used to inhibit the adhesion of bacteria or water-borne micro-organisms onto siufaces [19,20]. Bacteria are usually surrounded by exoceUular polysaccharides that can aid adhesion to clean surfaces. Thus prosthetic devices and vascular implants carrying blood suffer from the build up of biofilms, leading to blockages and infection. This build up can be markedly reduced...
