Vicky: I apologize for the delay in response. I am unaware of anyone testing the effectiveness of hydrogen peroxide inactivating ranavirus. I am copying the Global Ranavirus Consortium LISTSERV…there be may be someone on the list that has information. We summarized some information on disinfectants in this publication (see the Appendix): http://fwf.ag.utk.edu/mgray/Publications/Grayetal2017.pdf All the Best, Matt Gray ===================== Matthew J.

[External Email] Hi Dr. Gray - Sorry to bother you, but you may be the only person who would know this… Has anyone tested hydrogen peroxide as a disinfectant for Ranavirus? We are considering switching to 7-10% Hydrogen Peroxide across our herp collection to be sure to eliminate Cryptosporidium risk, and I wanted to see if it covered any of the other common herp diseases we also have to prevent as best possible. Bd/Bsal have been tested and it is effective at 6% H2O2 dilution for at least 15 minutes , but I cannot find any reference for hydrogen peroxide ever being tested for Ranavirus specifically… I did find the Bryan et al, 2009 paper where you all tested common disinfectants… but no H2O2 there. Any input would be helpful and appreciated. Thanks much! -Vicky Vicky A.
