I should be clear too and i will summarize what we were talking here.
- You came here to figure out why you lost your frogs and asking to help you to point things so if you ever get more frogs they wont go the same route.
- lots of knowledgeable people responded giving you an excellent advise and pointed what exactly was a problem and what you need to do
- you disregarded most of what you've been told and tried to defend why were you were doing the way you were.

Naturally certain questions are coming up.....

Now , yes it most likely was your fault frogs died, yes you should have done things differently and yes stuff happens and that is how we learn sometimes. It has happened to everyone here, me included, nobody's blaming you for that.

The problem though that you are planning on carry on doing what you please despite the advise you were given. And yes you quarantine newly purchased frogs. There is a proper protocol of doing so, that you were advised on.


Now m. Marinum. If the data you are talking about came from your vet, you need to change a vet, but you may do as you please of course.
But it will survive well past 30 days and no there are no disinfectants that kills it with 100% guarantee.
Just fyi there are multiple cases reported of m marinum isolated in bearded dragons, snakes, other species and humans. One of the cases that come to mind right now was bearded dragons were kept in old fish tanks that were not in use for 10 years.

So Ill repeat again, it is zoonotic bacteria, one of the most resistant ones, if it was diagnosed, you need to properly dispose everything that was in contact by burning it before throwing it away to minimize environmental risks of releasing in a landfills and further on, as well as health risks of workers who may come into contact with it.
It is dangerous for you too, granted most cases in human are presenting as very difficult to treat skin granulomas,but it can be worse be then that. Your sources of information were obviously mistaken.

I hope you think about and carry with dealing with it, if not for your frog health but for your own and those around you.
