RESUMO

Nonmucoid Pseudomonas aeruginosa isolated from corneal ulcers and contact lens cases and solutions were examined for their ability to adhere to polystyrene, glass, and hydrophilic contact lenses of varying water content and polymer composition. Adherence to the various substrates was strain specific. Adherence also was influenced by hydrophobicity and chemical composition of the substratum, as well as pH and electrolyte concentration. An extracellular polymeric adhesive appeared to be involved in the firm attachment of cells to soft contact lenses.
