Symptoms include peeling of shells, pigmentation, ulcers, paralysis of limbs, loss of feet and claws, and necrosis of internal organs. Animals such as crayfish, snakes, sea maggots, etc. that are used as feed, as well as soil, polluted water, etc., may be the source of infection. Bacteria enter the body through abrasions.

During treatment, use medicated bath and apply appropriate antibiotics to the whole body. However, chickens and turtles are allergic to certain antibiotics, so special attention should be paid when using them.
