Empyema thoracis due to actinomyces odontolyticus

Empyema necessitatis due to Actinomyces odontolyticus.

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...

Empyema thoracis due to Nocardia otitidiscaviarum.

We read with interest the article on pulmonary nocardiosis in southern Taiwan by Chen et al. In their study, eight of the 20 patients with pulmonary nocardiosis had pleural effusion and three of these patients had empyema thoraces. Among these three nocardial empyema cases, the authors reported a 61-year-old man with diabetes mellitus and chronic liver disease suffering from an acute course of ...

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...
