Long-term Survival and Virulence of Mycobacterium leprae in Amoebal Cysts
Figure 2
Confocal microscopy (600X) of fluorescent (PKH26) stained live M. leprae phagocytosed by A. polyphaga.
Nine successive focal planes (A–I) from top through the bottom of the amoebae were imaged showing the bacillus to be located internally rather than simply being adsorbed on the protozoan exterior.
