The study into the manner in which disease causing agents-microorganisms such as bacteria, viruses, fungi and parasites-cause infection in their hosts is microbial pathogenesis. The subject deals with mechanisms and processes by which pathogens invade, survive inside and damage tissues of a host to cause illness.

As a matter of fact, it really matters much to the mechanisms by which microbes cause disease: virulence factors that enable microbes to infect and evade their host’s immune system. They are toxins, adhesin molecules, and enzymes contributing to pathogenesis and helping in facilitating evasion of the immune response. For example, exotoxins from bacterial pathogens could interfere with cellular activities, or viruses might use specific surface proteins for entry into host cells.

In general, the study of microbial pathogenesis involves host-pathogen interaction, which includes how the host’s immune system responds to the infection and how pathogens adapt to a variety of host environments. The studies in this field further include how diseases spread and the epidemiology of infectious outbreaks.

These advances in microbial pathogenesis also open up avenues for novel diagnostic tools, treatments, and vaccines. Scientists may come up with therapies that will effectively inhibit the growth of pathogens or enhance the immune system. Understanding the molecular basis of antibiotic resistance helps in proper strategies to combat resistant strains of bacteria.

Generally, the advance of our knowledge about infectious diseases and public health benefits from improvement in better prevention and treatment strategies depends on microbial pathogenesis.
