Pure silver-, silver oxide- and silver chloride-treated surfaces in comparison to polypropylene inhibited both growth and adherence from saline ofSerratia marcescens, Staphylococcus epidermidis, Pseudomonas aeruginosa andCandida albicans. These same organisms demonstrated enhanced adherence to an Ion-Beam-Assisted-Deposited silver surface followed by loss(More)
Cells of Pseudomonas aeruginosa were adhered to polymethyl methacrylate, polyvinyl acetate, polyvinyl chloride, polyhydroxyethyl methacrylate, mixed-acrylic, silicone, and natural latex materials. Planktonic bacteria and bacteria that adhered to the test materials were compared for their uptake of either L-[3,4,5-3H] leucine or [methyl-3H] thymidine during(More)
PURPOSE To examine the early host response to Pseudomonas aeruginosa challenge in the extended contact lens-wearing rat model. METHODS Lewis rats were fitted with extended-wear lotrafilcon A hydrogel lenses in the left eye, and the right eye served as the control. Bacterial challenge was initiated in the experimental eye by fitting a bacteria-soaked(More)
PURPOSE To compare the relative degrees of adherence of a clinical strain of Pseudomonas aeruginosa to the optic material of four intraocular lenses (IOLs). SETTING Center for Applied and Environmental Microbiology, Georgia State University, Atlanta, Georgia, USA. METHODS Intraocular lens optics made of poly(methyl methacrylate) (PMMA), AcrySof-acrylic,(More)
Strains of Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, Enterococcus faecalis, and Klebsiella pneumoniae, mostly from complicated urinary tract infections, showed reduced adherence to silver-treated silicone or latex catheters as compared with latex or silicone catheters. The relative degrees of cell adherence to catheters at 2 h or 18 h, as(More)
Bacteria commonly associated with nosocomial urinary tract infections were examined in vitro for their relative adherence to latex, 100% silicone-, hydrogel-coated latex-, and hydrogel/silver-coated latex urinary catheters. Degrees of adherence within 2 h were determined with cells radiolabeled with leucine. Adherence was greatest and equivalent on silicone(More)
We determined the relative minimal inhibitory and minimal amoebicidal concentrations of chlorhexidine digluconate and polyhexamethylene biguanide for four species of Acanthamoeba. The amoebae were grown in peptone-glucose-yeast extract broth for 72 h in tissue culture flasks. Either washed trophozoites (approximately 10(5)) or cysts (approximately 10(5))(More)
OBJECTIVES To determine the effect of Pseudomonas aeruginosa and Staphylococcus epidermidis on the binding of Acanthamoeba species to hydrogel lenses. METHODS Cells of amebae and bacteria were incubated with different types of hydrogel lenses. Densities of amebae that were bound to the lenses after rinsing were determined from direct counts with a cell(More)
