Such a defect in actin-based motility occurred, and bacteria were able to escape the vacuole; this was unrelated to the expression level of RickA.
14 Upon invasion, a population of bacteria is able to escape from the phagosome and colonize the nutrient-rich cytosol where they replicate rapidly.
Several systems specific to Waddlia are likely involved in resistance to professional phagocytes such as amoebae and/or macrophages where the bacterium is able to escape lysosomal degradation and to grow rapidly [15], [35].
It may be breakdown products from the MHC proteins themselves, or it may be the secretions of bacteria that are able to escape the attentions of particular MHC proteins.
However, the intra-macrophage CFUs were significantly higher in SHIP+/+ BMM at 2 h hours post infection, suggesting that a greater number of bacteria have been able to escape phago-lysosomal fusion.
However, once bacteria evolve high levels of resistance, they are able to "escape and radiate" into the three colony types to take advantage of the ecological opportunities available in the test tube.
The secretion is often sticky and helps keep the skin moist, protects against the entry of moulds and bacteria, and make the animal slippery and more able to escape from predators.
Most importantly, however, our data shows for the first time that this bacterium can not only persist for several days inside macrophages, but ultimately is able to escape the intracellular confinement and proliferate rapidly in the conditioned media.
Probably the activity exerted by these extracts is due to the presence of natural bioactive compounds with either a new mode of action or which are able to escape or to inhibit the mechanism of resistance of these MDR bacteria.
For M. marinum it has been shown in cell cultures that they are able to escape the phagosomal compartment, which was shown in our model to result in ~13% of bacteria residing freely in the cytoplasm.
