In order to ensure that BIOHM was in a class of its own when it came to both the science and quality, Dr. Ghannoum’s team acquired the bacterial and fungal strains in BIOHM from the American Type Culture Collection (the ATCC). The ATCC is considered the gold standard in the scientific community when it comes to sourcing microorganisms. While Dr. Ghannoum’s laboratory has a collection of over 30,000 strains of fungi (the largest collection in the United States outside the Centers for Disease Control), on the rare occasion he does not have a particular strain needed for a study, the ATCC is one of the first places he turns to in order to acquire the needed microorganism.
