Identification of Mutations Involved in the Requirement of Potassium for Growth of Typical Melissococcus plutonius Strains

摘要

Melissococcus plutonius is a fastidious honeybee pathogen, and the addition of KH2PO4 to culture medium is required for its growth. Using genome sequences and a newly developed vector, we showed that mutations in genes encoding Na+/H+ antiporter and cation-transporting ATPase are involved in the potassium requirement for growth.
