: Report of a case.
is the most commonlyfound species of the genus and the most common cause of actinomycosis.
Actinomycosis is an uncommon chronic infectious disease caused by Bacterium Actinomyces Israelii
, which is an anaerobic gram positive oral flora that may become pathologic due to poor oral hygiene, dental/periodontal problems, trauma or following oral surgical procedures.
El Actinomyces israelii
es la especie mas frecuentemente asilada, aunque existen otras que tambien pueden causar infeccion (1).

Actinomycosis is characterized by granulomatous and fibrotic lesions, which tend to break down and form abscesses that drain through multiple sinuses.11 Typical "sulphur granules" occur in these abscesses.11 The disease is caused by Actinomyces israelii
, the anaerobic organism producing filamentous branching hyphae.
Johnson  et al., noted Actinomyces israelii
in periodontitis cases.
, a very aggressive organism commonly found in association with TOA, requires both surgical treatment and a 6-week to 3-month course of penicillin.
