Cow mandible with honeycomb network of abcesses from actinomycosis infection. Actinomyces bovis is a gram-positive bacteria that leads to granulomatous abcessing of infected areas of the head and neck in cattle which can destroy bone. A rel…ated bacterium A. israelii causes a simillar but more rare condition in humans. In cattle the condition is referred to as “lumpy jaw.” Untreated, the infection will produce copious amounts of pus whichs discharges from the skin. Actinomyces were one thought to be a fungus because of their branching filamentous structures.
