The rising tide of bloodstream infections with Actinomyces species: bimicrobial infection with Actinomyces odontolyticus and Escherichia coli in an intravenous drug user

Clinicians of all specialties need to be aware of a recent, nationwide increase in the number of Actinomyces bloodstream infections. We report a case of bimicrobial bloodstream infection with Actinomyces odontolyticus and Escherichia coli in an intravenous drug user. A 36-year-old, male intravenous drug user was admitted with acute-onset pleuritic chest pain, back pain, pyrexia, tachycardia, ta...

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.

Empyema necessitatis due to Actinomyces odontolyticus.

Two new serological groups of Actinomyces.

Actinomyces odontolyticus and A. viscosus are designated as group E and group F in the serological grouping of the Actinomyces.

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...
