Concept introduction:

Microorganisms that have the ability to cause infectious diseases are called as pathogens. Illness in an individual is caused either by disturbing the normal metabolic activity of the host or by inducing the host’s immune system to produce a response. Pathogenic bacteria have developed a wide range of mechanisms to infect the human system. Some microbes have the ability to produce toxins, poisonous substance, which contribute to the pathogenicity of the microorganisms. Such pathogens colonize and invade the human system, and ultimately cause serious diseases in human.
