Levinthal’s Medium Base 500G

Levinthal’s Medium Base is recommended for cultivation of Haemophilus species. Addition of sterile rabbit or human blood makes media selective. Blood provides two factors, which supports growth of Haemophilus species: factor-X and factor-V. Pathogenic Haemophilus species are presumptively identified by determining in vitro growth requirements for X and V factors and by haemolytic reactions.
