In Vitro Effectiveness Of Acid And Aldehyde Base Surgical Instruments Disinfectansts Against Various Microorganismis

Abstract

In this study, in order to define how effective aldehyde based surgical instrument disinfectant with acid based is to which concentration against Staphilococcus aureus (ATCC 29213), Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 23853),Candida albicans (ATCC 10231) strains used for Test microorganisms, final microorganisms was disinfectant into the different concentrations of the disinfectant to be tested by being prepared as 2-5x109 CFU/ml according to the McFarland 5 cloudiness of Test disinfectant. After disinfectants were activated with microorganisms at previously experimented 30 seconds 1,5,15 and 30 minute
periods, colony counts at 1 ml. Levels were performed by way of cast-cultural plaque metod. Consequently, it was determined that 0.01% concentration of aldehid based surgical instrument disinfected was effective against test microorganisms in 30 seconds,0.1% concentrations of the disinfectant containing peracetic acid was effective against Staphilococcus aureus in 30 seconds, while other test microorganisms were effective in 30 seconds at 0.5% concentrations. It was also determined that 0.1% concentrations of the disinfectant containing citric acid were effective against all test microorganisms in 30 seconds.
