Modulation of Host Cell Death and Lysis Are Required for the Release of .

is a -like bacterium and emerging pathogen of the respiratory tract. It is an obligate intracellular bacterium with a biphasic developmental cycle, which replicates in a wide range of host cells. The life cycle of has been shown to proceed for more than 12 days, but little is known about the mechanisms that mediate the cellular release of these bacteria.
