Cohn et al. improved the formulation of oleic acidalbumin agar to obtain faster, more luxuriant growth of mycobacteria. Their addition of 0.1% casein hydrolysate improved the recovery of isoniazid-resistant strains and resulted in the Seven H11 formulation. The addition of antimicrobials to make Selective Seven H11 results in the decreased growth of contaminating organisms. Use of agar-based media such as Seven H11 Agar can yield positive results six to fourteen days earlier than with egg-based media (e.g., Lowenstein-Jensen), since the clarity of Seven H11 allows for microscopic examination of the plate in contrast to opaque media products.
