Great job, Carlos. Mycobacterium is commonly found in water. People keeping highly aquatic frogs, such as, Xenopus (ACF), Pipa (Surinam toads), and Hymenochirus (ADF) should be especially aware of these nasty organisms. Treatment is not recommended since there is a chance of spreading the disease. Any frogs having the infection should be culled and properly disposed. Some species of bacteria can be transmitted to humans in the form of amphibian or fish tuberculosis. Symptoms include ulcerated skin lesions, lethargy, weight loss and coelonic distention (extreme bloating of the abdominal cavity and acute damage to the digestive tract), or the disease can cause sudden death without the skin lesions. This bacteria is assumed to be in all aquariums and will manifest itself under the right conditions (especially in instances of poor husbandry). Much easier to prevent than cure.

All keepers, especially those with aquatic frogs, must maintain proper water chemistry and cleanliness at all times.
