title: Persistence of associated gram-negative bacteria in experimental actinomycotic lesions in mice.
abstract: Mixed actinomycotic infections were established in a susceptible weanling mouse model by using combinations of Actinomyces israelii and Eikenella corrodens or A. israelii and Actinobacillus actinomycetemcomitans. Acute lesions caused by either of the gram-negative organisms alone were resolved within a few weeks; however, these organisms persisted up to 3 months in chronic lesions in combination with A. israelii.
