Just a little more from the article I referred to earlier:
"The story begins in 1926 when J. D. Aronsen studied a number of salt-water
fish, which had died in the Philadelphia Aquarium, USA. He found that the
fish had a tuberculosis-type disease, with large nodules or ulcers
throughout many of their tissues, eg spleen, liver, kidney, gills, heart and
intestine. From the nodules Aronsen cultured a bacterium which he named
Mycobacterium marinum. Injections of bacteria from culture killed goldfish,
frogs, pigeons and mice but had only minor effects on guinea pigs and rabbits."
