Actinomycosis occurs rarely in humans, but rather frequently in cattle as a disease called "lumpy jaw". This name refers to the large abscesses that grow on the head and neck of the infected animal. It can also rarely affect sheep, swine, horses, dogs, and other mammals.
bovine actinomycosis, 3-year-old bull, 2-month evolution bony swelling of the right maxillae thick matter (top) and old fistulous granulomas. Actinomycosis is an infection caused by a bacterium of the genus Actinomyces, usually Actinomyces bovis; the disease it causes has several common names. When it is a moveable tumour or lump on the jaw ...
Actinomycosis is pathognomonic for abscesses containing "sulfur" granules, and its colonies appear basophilic with club-shaped reaction products on a histological preparation. [6] [7] Lumpy jaw is commonly treated with broad-spectrum antibiotics with varying success, [8] and can be a major economic loss for producers in countries where it is ...
Actinomyces species may form endospores, and while individual bacteria are rod-shaped, Actinomyces colonies form fungus-like branched networks of hyphae. [3] The aspect of these colonies initially led to the incorrect assumption that the organism was a fungus and to the name Actinomyces, "ray fungus" (from Greek actis, ray or beam, and mykes ...

Actinomyces and its associated species have, for a long time, been implicated in human infections, particularly those of the mouth, pharynx, distal esophagus, and genitourinary tract. [9] Within the last 10 years, A. massiliensis has been detected in blood, and most Actinomyces bacteremias stem from oral sources. [ 9 ]
In 1877, he described the etiologic agent of bovine actinomycosis ("lumpy jaw"), an organism that is now referred to as Actinomyces bovis. [3] He is credited with describing the inclusion bodies found in tissue cells in fowlpox. These bodies contain the fowlpox virus and are now referred to as Bollinger bodies.
