Fig. 3From: Comparative in vitro effectiveness of a novel contact lens multipurpose solution on Acanthamoeba castellaniiBactericidal effectiveness of various contact lens care solutions against S. marcescens. A microbial suspension of S. marcescens was added to each solution and incubated at contact times noted. Each mixture was diluted, streaked onto plates, and enumerated for log reduction calculations. Three-log reduction threshold is denoted by the horizontal line from the x-axisBack to article page
