Abstract
Mycobacterium tuberculosis is able to colonize host cells, and it is now well admitted that the intracellular stage of the bacteria contributes to tuberculosis pathogenesis as well as to making it a persistent infection. There is still limited understanding on how the tubercle bacillus colonizes the cell and what are the factors impacting on its intracellular persistence. Recent advances in imaging technique allow rapid quantification of biological objects in complex environments. Furthermore, M. tuberculosis is a microorganism that is particularly genetically tractable and that tolerates the expression of heterologous fluorescent proteins. Thus, the intracellular distribution of M. tuberculosis expressing fluorescent proteins can be easily quantified by the use of confocal microscopy. Here we describe high-content/high-throughput imaging methods that enable tracking the bacillus inside host settings, taking into account the heterogeneity of colonization.
