TL;DR: Adhesion to the hydrogel/silver catheters by both Gram-positive- and Gram-negative bacteria most commonly associated with nosocomial urinary tract infections, including a strain of Pseudomonas aeruginosa noted for its superior adhesion capacity, was significantly lower than the adhesion toThe control all-silicone catheter.

TL;DR: Enhanced efflux pump tolerance to FCZ appeared to be induced within the initial 15 min of attachment in a subset of cells that were firmly attached to the substrata, and retained a four- to eightfold increase in tolerance compared with the tolerance of planktonic cells for at least two generations.

TL;DR: Biofilms, adhered microorganisms embedded in a glycocalyx, in contact lens storage cases were not always inactivated by the addition of fresh solutions, and cleaning and periodic replacement of contact lensstorage cases is recommended.

TL;DR: The wetting and soaking solutions and contact lens cases of eye clinic patients commonly were contaminated with gram-negative bacteria during their use, and bacteria were recovered at densities of greater than 10 cells per ml and typically persisted in the solutions.

TL;DR: Self-inoculation of the eye with contaminated saline is a hazard for soft contact-lens wearers who use home-prepared saline solution and commercial distilled water, even brands recommended for use with soft contact lenses, was found to be contaminated with gram-negative bacteria before use.
