Bifidobacterium (Actinomyces) eriksonii infection.

Abstract

This case is an example of infection with a recently reclassified organism, Bifidobacterium eriksonii. It presents 2 unusual characteristics that have not been reported with Bifidobacterium infections in general and Bifidobacterium eriksonii infections in particular. These characteristics are (1) a miliary pattern on chest roentgenograms suggesting hematogenous spread of the organism and (2) widespread noncaseating granulomas pathologically.
