| blue white colour selection | <molecular biology, procedure> Method for identifying bacterial clones containing plasmids with inserts. Many modern vectors have their polycloning site within a part of the LacZ gene encoding _ galactosidase, which provides _ complementation in an appropriate mutant E. Coli strain. This means that a re ligated (empty) vector will produce blue colonies when grown on plates containing IPTG and X gal, but colonies with a substantial insert in their plasmid's polycloning site are unable to produce functional _ galactosidase and so produce white colonies.

| Bouffardi's white mycetoma | <dermatology> A form of mycetoma common in India and found occasionally in Somalia, caused by the organism Streptomyces somaliensis; in this variety, the muscles, tendons, and bones of the foot are destroyed by the disease process; numerous draining sinuses discharge yellowish grains, clustered like fish roe.
