Liver Abscess
Liver abscesses are formed by pathogenic toxins that have escaped the rumen.
When the rumen wall is damaged by the effects of acidosis, bacteria can enter the bloodstream and proliferate throughout the liver.38ReferenceView allGalyean M. L. and Rivera J. D. 2003.
- The most common causative agents are: Fusobacterium necrophorum (100% of cases) and Arcanobacter (now Trueperella) pyogenes (35% of cases).
- Both are part of the normal microbiotaGlossaryView allMicrobiota
A microbiota is the whole of the ecosystem (bacteria, yeast, fungi and viruses) living in a specific environment. Intestinal microbiota was previously called “intestinal flora.” found in the rumen. - Toxins produced by these bacteria lead to a coagulative necrosis that develop into encapsulated abscesses over time and the form of a fibrous scar (up to 15cm in size).
