Latest Patents

Dahl holds a patent for "Allelic exchange mutagenesis in Map." This invention provides efficient allelic exchange methods to generate directed mutations within genes of slow-growing strains of mycobacteria, such as subsp. (Map), Map 10, or GFP-expressing Map K-10. The patent utilizes a phage-delivery system and demonstrates high efficiency in allelic exchange. Additionally, it describes non-naturally occurring slow-growing strains of mycobacteria with at least one gene deletion, including pknG, relA, lsr2, panC, panD, proC, trpD, sapM (MAP3432), lysA_1, leuD, and leuC. The invention also includes deletion mutants at the orthologous loci of two known virulence genes in pathogenic mycobacteria and one gene related to colony morphology and biofilm formation in fast-growing mycobacteria. Furthermore, the patent outlines novel vaccines comprising such deletion mutants and methods for protecting mammals from virulent Map using these vaccines.
