==Overview==
''Actinomyces bovis'' is a species of the ''[[:Category:Actinomyces|Actinomyces]]'' genus.
It is found naturally in the oral cavity of cattle and prefers anaerobic conditions but is not a strict anaerobe. Entry of the organism into tissues is following trauma to the mucosa from rough feed or tooth eruption. It causes [[Granulomatous Inflammation|granulomatous inflammation]] of soft tissues and bone, causing [[Mandibular Osteomyelitis|lumpy jaw]].
It usually invades the mandible to cause [[Osteomyelitis|osteomyelitis]] and may extend to surrounding muscles.
==Pathology==
The lesion begins as a painless swelling of the affected bone, the swelling becomes more painful and enlarges over a number of weeks, gaining fistulous tracts which discharge pus. The organisms are found in yellow sulphur granules and have club colony formation. Colonies adhere to agar media and are non-haemolytic.
==Treatment==
Surgical treatment is possible when the lesions are small and prolonged parenteral penicillin treatment may be beneficial early in the disease.
