Avian tuberculosis is a highly contagious bacterial disease caused by Mycobacterium avium that affects all avian species, especially waterfowl. The disease develops gradually over a course of weeks, months, or even years---and is chronic and progressive in nature. M. avium primarily targets the duck's liver and digestive tract, and later disseminating into the lungs, air sacs, spleen, bone marrow, and skin.
How Ducks Become Infected
Ducks become infected with M. avium through ingestion or inhalation of the bacteria while dabbling in their environment. Higher numbers of infective bacteria are found around the water. Infected birds will continuously shed the bacterial organisms in their feces, leading to high levels of contamination within their environment. M. avium is highly resistant to environmental elements and has been found to survive in soil for up to 4 years.
