Description: Caption:
This photomicrograph depicts two ciliated Tetrahymena pyriformis protozoa containing red chains of intracellular, Legionella pneumophila bacteria, which were undergoing multiplication. Experiments have shown that L. pneumophila bacteria can reproduce intracellularly acting as a parasite inside of the ciliated protozoan, T. pyriformis, forming “serpentine chains of approximately 103 L. pneumophila” organisms.
