Clogged bile ducts in toxic Hepatoenteritis infectious avian
Bile canaliculi and intrahepatic channels are a suitable habitat for growth of whole bacteria from the intestine or the yolk, resistant to bile acids. In this anatomical settlement (to safeguard antibiotics except those with liver whole cycle, without microbial competition) these microorganisms grow and may even clog the duct (1st photo). From this moment the liver acquires a greenish coloration by the accumulation of bile and bacteria own blue-green pigments (cyan pio). If the animal survives the toxic effect of bacteria can form bile fistulas as shown in 2nd photo.
