It tends to spread rapidly and is often fatal.
Maybe sensitive to some antibacterials such as "azithromycin, clarithromycin, linezolid, mupirocin, doxycycline, minocycline, and tigecycline" (PubMed) and there is some synergism with antifungals (PubMed).
Causes "swamp cancer" in horses, cattle, dogs, and cats.
