Growth inhibition of Aeromonas salmonicida and Yersinia ruckeri by disinfectants containing peracetic acid [abstract]. 17th EAFP International Conference on Diseases of Fish and Shellfish, September 7-11, 2015, Las Palmas. p. 189.Interpretive Summary:
                                Technical Abstract: Peracetic acid (PAA) is an agent used for disinfection in aquaculture.  PAA contributes to sustainable aquaculture, because it releases no harmful residue in the environment.  However, there is lack of guideline about the effective application of different PAA products against various pathogens in practical aquaculture disinfection.  The aim of our study was to compare the effectiveness of six commercial PAA products with different molecular PAA:H2O2 ratios to reduce bacterial growth of A. salmonicida and Y. ruckeri, and to determine effective concentrations and exposure times.
All products reduced colony forming units (CFUs) of A. salmonicida and Y. ruckeri.  Products with a higher concentration of PAA (versus H2O2) did inhibit growth better than products with lower PAA and higher H2O2 concentrations; H2O2 is not the driving force in the reduction of A. salmonicida and Y. ruckeri growth by PAA in vitro.  The practical application of the products with high PAA concentration should be prioritized if these pathogens are diagnosed.
