==Overview==
 
''Actinomyces viscosus'' is a species of the ''[[:Category:Actinomyces|Actinomyces]]'' genus. It is a commensal of the oral cavity of dogs and humans.
 
 
 
==Characteristics==
 
''A.viscosus'' rods are contained in soft grey granules which release the organism when squashed. There are two types of colonies: large and smooth colonies with V, Y and T configurations or small and rough colonies with short branching filaments. They grow in 10% carbon dioxide and usually respond to penicillin.
 
 
 
==Pathogenesis==
 
''A.viscosus'' is involved in canine actinomycosis and causes localised, subcutaneous pyogranulomatous lesions and fibrovascular proliferation of peritoneal ([[Peritonitis - Cats and Dogs|peritonitis]]) and pleural surfaces in dogs.
 
It leads to [[Pyothorax|pyothorax]], respiratory distress, cutaneous pustules in horses and abortion in cattle.
