Bronchial tissue Gram stain showing intrahistiocytic coccobacillary forms of Rhodococcus equi.Original magnification, x 1,000. B.Open lung biopsy showing coalescent microabscesses with numerous histiocytes containing Rhodococcus equi organisms. Gram stain of colony growth. A. haemolyticum are classically associated with causing sore throat, particularly in late teenagers. They can cause enlarged lymph nodes in the neck and rash and therefore mimic Streptococcus pyogenes (Group A Streptococcus) infection. A 4-h alpha-mannosidase test for identification of Arcanobacterium haemolyticum strains (n = 139) and differentiation of A. haemolyticum from Actinomyces pyogenes strains (n = 30) and other gram-positive rods was evaluated. Arcanobacterium haemolyticum on gram stain of growth from throat culture.

demonstrates delicate, curved, gram-positive rods with pointed ends and occasional rudimentary branching. This branching is more pronounced after these organisms have been cultured anaerobically. Arcanobacterium spp. stain unevenly after 48 hours of growth on solid media and also exhibit coccal forms. Gram Stain of Arcanobacterium haemolyticum. Gram Positive with Crystal Violet (Arcanobacterium haemolyticum) Hemolysis of Arcanobacterium haemolyticum.
