Avian hepatitis caused by Shigella sp.
Shigella sp. is an enterobacterium with fecal transmission that mainly infects the animal orally, through drinking water. Some wild or urban birds and flies act as reservoirs and contaminate water. The most frequent symptomatology is dysentery, although sometimes birds develop an hepatic inflammation with point-shaped abscesses in the hepatic mass, as it can be seen in the picture. It is not known to cause septicemia.
