Killing ofMycobacterium aviumsubspeciesparatuberculosiswithin macrophages

Mycobacterium aviumsubspeciesparatuberculosis(M. paratuberculosis) is a facultative intracellular pathogen that resides within host macrophages during infection of ruminant animals. We examined survival ofM. paratuberculosisinfections within cultured macrophages to better understand the interplay between bacterium and host.
