title: Antimicrobial effectiveness of silicone oil, heavy silicone oil and perfluorodecaline against Bacillus cereus.
abstract: The purpose of this work is to study the effectiveness of silicone oil, heavy silicone oil and perfluorodecaline against Bacillus cereus. For this we tested the antimicrobial activities of three intraocularly used liquids--silicone oil (Siluron 1000), heavy silicone oil (Densiron-68) and perfluorodecaline (F-Decalin)--against B. cereus (NCTC 9946). The antimicrobial effects of silicone oil, heavy silicone oil and perfluorodecaline were determined by the growing capability of the microorganism. We found that the number of B. cereus decreased in all three concentrations of silicone oil. The bacteria grew for approximately 2 weeks in heavy silicone oil and declined after 17 days. Perfluorodecaline significantly reduced B. cereus colonies and was the most effective of the liquids. In conclusion, silicone oil and perfluorodecaline seem to be effective against B. cereus.
