The genera Actinomyces,Bifidobacterium,Eubacterium,Eggerthella,Collinsella,anaerobic Lactobacillus,Atopobium,and Propionibacterium are among the anaerobic,gram-positive,non-spore-forming bacilli.Mobiluncus,a cause of bacterial vaginosis,is usually diagnosed on Gram stain of vaginal secretions by observation of gram-variable,curved rods with tapered ends.It is rarely isolated in the clinical laboratory because vaginal secretions are not acceptable specimens for anaerobic culture.
