Detailed explanation-1: -Unlike more complex forms of life, bacteria carry only one set of chromosomes instead of two. They reproduce by dividing into two cells, a process called binary fission. Their offspring are identical, essentially clones with the exact same genetic material.
Detailed explanation-2: -A smaller group of intracellular bacteria, including Shigella spp., the closely related enteroinvasive Escherichia coli (EIEC), Listeria monocytogenes, Listeria ivanovii, and Ricksettia spp., can escape from the primary phagosome into the host cell cytosol where the bacteria proficiently replicate.
Detailed explanation-3: -Bacteria have evolved various mechanisms to adhere to the surface of organs in contact with the external milieu, such as the intestine. In addition, some bacteria can adopt an intracellular lifestyle and get internalized inside various host cells types to replicate away from the humoral host immune defenses.
