Microbiome-based informed method to formulate live biotherapeutics
Methods of formulating live biotherapeutics are disclosed in which a deficiency or excess of a specific bacterial strain in a person's microbiome is identified by comparing a gene-specific characterization of the person's microbiome against a comprehensive, non-redundant reference gene catalog, and the biotherapeutic is formulated by selecting bacteria to address the deficiency or excess. Embodiments include the formulation of live biotherapeutics for improving the health of a person's vaginal microbiome, i.e. using a vaginal reference gene catalog, and may be suitable for ameliorating, treating, or preventing a malignancy such as a cancer of the female genitourinary system.
