Secondary peritonitis by Actinomyces odontolyticus

Actinomyces odontolyticus bacteremia.

We describe two immunosuppressed female patients with fever and Actinomyces odontolyticus bacteremia, a combination documented once previously in an immunocompetent male patient. The patients were treated with doxycycline and clindamycin; these drugs, with beta-lactams, are effective treatment for A. odontolyticus infections.

Actinomyces Odontolyticus - Associated Bacteremia

Many Actinomyces species are part of the oral microflora of humans. Actinomyces odontolyticus associated infections are exceptionally rare, presenting an endogenous infection originating from mucous membranes. Immunodeficiency is often complicated by severe opportunistic bacterial infections leading to critical condition of the patient. We report a case of an immunosuppressed patient with fever...

Malar mass due to Actinomyces odontolyticus.

Actinomyces odontolyticus was isolated from a patient with a soft tissue mass in the malar region. The organism was identified on the basis of morphological, cultural, and biochemical characteristics. On histological examination, the tissue mass contained several granulomatous foci with small, basophilic staining areas resembling microscopic sulfur granules. This is believed to be the first rep...

Actinomyces odontolyticus: Rare Etiology for Purulent Pericarditis

Purulent pericarditis is one of the most common causes of cardiac tamponade and if left untreated has a mortality of 100%. Staphylococcus aureus and Streptococcus pneumonia have been implicated as the main etiology of purulent pericardial effusion followed by fungi and anaerobic sources. Actinomyces odontolyticus pericardial involvement has been reported in the literature only once. To our know...
