Hi, has anybody had any issues with Mycobacterium marinum with dart frogs. M. marinum is apparently common in fish and can infect any animal, though more commonly poikilotherms. My main concern is that I have rocks, tanks and wood from fresh and salt water aquariums that I would like to use in a dart frog vivarium. Some web sites say it is very persistent in the soil, almost ubiquitous. If this is the case then it would likely be present in plants and soil so wood and rocks from an aquarium would pose only a slightly increased chance of inoculation ?
