vaccine that also express M. ulcerans antigens prolong the survival of mice after M. ulcerans infection. As of 2019, no vaccine tested completely protects mice from infection. M. ulcerans can be grown in laboratory media, although its slow growth makes it challenging to study. Bacteria plated on laboratory media can take up to three months to form visible colonies. Strains of M. ulcerans used in laboratories are less standardized than the mice they infect; different laboratories use different strains based on convenience and accessibility. Three M. ulcerans strains are particularly common, each isolated from an infected person: "Cu001" from Adzopé, Côte d'Ivoire in 1996; "Mu1615" from Malaysia in the 1960s; and "S1013" from Cameroon in 2010.
