Late prosthetic hip joint infection with Actinomyces israelii in an intravenous drug user: case report and literature review.

Actinomyces israelii is the most commonlyfound species of the genus and the most common cause of actinomycosis.

Actinomyces israelii ha sido repetidamente citado como una causa de fracaso del tratamiento endodontico.

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.

At 3 months post-therapy, significantly higher levels of Actinomyces israelii, Campylobacter rectus, Fusobacterium periodonticum, Parvimonas micra, Prevotella nigrescens, Tannerella forsythia, Neisseria mucosa, and Streptococcus anginosus were found in the CKD group compared with the C group (p < 0.

El Actinomyces israelii es la especie mas frecuentemente asilada, aunque existen otras que tambien pueden causar infeccion (1).

La composicion microbiana de la placa supragingival se caracteriza por la presencia de Streptococcus sanguis y en menor proporcion los Actinomyces viscosus, Actinomyces naesludii y Actinomyces israelii, a medida que la placa madura aumentan las formas de estreptococos como el Streptococcus mitis, Streptococcus sobrinus y Streptococcus mutans y Actinomyces odontolyticus, entre otros.

Actinomyces israelii, a very aggressive organism commonly found in association with TOA, requires both surgical treatment and a 6-week to 3-month course of penicillin.
