Fluconazolo and Oodiniasi

Fluconazolo and Oodiniasi

Recent indirect experiences would suggest that Fluconazole, now used successfully to eradicate Derbesia and Bryopsis from our aquariums, is able to counteract an infection that often afflicts the fishes in our aquariums: Oodiniasis. Three of our aquarist friends, Valente Damiano, Francesco Accorinti and Alessandro Natale, recently shared some posts in which they report that having had to use Fluconazole to solve an algae problem, they had noticed a complete recovery of some fish that suffered from Oodiniasis at that time.

For the uninitiated, Oodiniasis is an infection caused by a Dinoflagellate, Amylodinium ocellatum. The interesting aspect that makes us think is that ergosterols, of which Fluconazole blocks the biosynthesis, are present in the cell membranes of many species of Dinoflagellates. It is therefore not excluded that these constituents are also present in this type of Dinoflagellates and that their inhibition may be deleterious to their survival. If all this were confirmed by further experiences in this regard, it would in fact be a really important discovery, which would avoid numerous headaches related to this disease. I remember that currently for the treatment of Oodyniasis reference is made to methods that are difficult to implement as they involve the use of drugs that are difficult to manage: Copper salts and drugs such as quinine which, if not used at their best, can cause serious problems to the tank.

Fluconazole, on the other hand, now seems to have passed numerous tests and proved to be well tolerated by the aquarium ecosystem. It is still too early to be able to say with certainty that Fluconazole is effective against Oodiniasis: there is a lack of further experience in this regard. I would therefore like to make an appeal, on behalf of all fans, to anyone who decides to experiment with the drug for this eventuality, to kindly share their experience with the rest of the group. Anyone wishing can also contact me directly through Messenger or the Ballingmania website.

I take this opportunity to point out that Fluconazole is subject to medical / veterinary prescription and therefore cannot be used except on the prescription of a Veterinarian. It is also useful to specify that the use of antibiotic drugs can induce phenomena of antibiotic resistance and that their use must always be recommended by the Veterinarian who will evaluate the advisability of using them from time to time. Thanks again. I thank Damiano Valente, Francesco Accorinti and Alessandro Natale for bringing back their precious experience and my friend Marco Paci for their fundamental collaboration.
