Project description:Transcriptional profiling of Mycobacterium tuberculosis H37Rv and Mycobacterium bovis Ravenel before (i.e., log-phase control) and at 24h and 96h after nutrient starvation. The transcriptional profile of the two strains were compared at log phase, and after 24h and 96h of starvation. In addition, the response of each strain to starvation was examined after 24h and 96h of starvation.
Project description:Mycobacterium bovis (M. bovis) and Mycobacterium avium subspecies paratuberculosis (MAP) are important pathogens of cattle, causing bovine tuberculosis and Johne’s disease respectively. M. bovis and MAP infect residential macrophages in the lung and intestines respectively and subvert the macrophage biology to create a survival niche. To investigate this interaction we simultaneously studied the transcriptional response of bovine monocyte-derived macrophages to infection with two strains of M. bovis (AF2122/97 and G18) and two strains of MAP (C & L1).
