We are a product of our genes, so they say; however, we are also populated by microbes. Some we cannot do without, but others wait around until our defenses are down and then they strike. During your examination of the topics in this chapter, consider the following:
Which characteristics of bacterial cells allow them to cause disease in humans?

To determine: The characteristics of bacteria cells that allow them to cause disease in humans.
Introduction: Prokaryotes are the oldest form of life on Earth that belongs to the domain Archaea and bacteria. They are single-celled microscopic organisms and they do not possess true nucleus or membrane-bounded organelles. The prokaryotes are found to be both beneficial as well as harmful to humans.
Explanation of Solution
The bacterial cells possess certain characteristics that make them cause infections or diseases in humans. The virulence factors are the characteristics of the bacteria that enhance its ability to cause disease. The cell structure of the bacteria acts as the virulence factors that include: LPS (lipopolysaccharide), S-layer, mycolic acid, fimbria, capsule, pili, and endospores.
