Basics of Medical Microbiology

Medical microbiology deals with studying the relationship between host and parasite and understanding the causative agent of disease.

In our daily life, human beings are constantly exposed to micro-organisms.
The interaction between human and micro-organisms may be useful or harmful interaction.
Parasitism can be explained a condition in which microbial population is benefited and the host is harmed.

Some important concepts in medical microbiology

1. Infection

  • In infection, a pathogen enters in a host body, lives and multiply in the host.
  • Generally, infection is caused due to the failure of host defence mechanism.
  • Due to the failure of host defence mechanism the microbial cells leads to infection.

2. Disease

  • The disease is a result of infection
  • When a disease is established the normal functioning of host body is disturbed and this disturbance results in signs and symptoms.
  • These pathogens not only multiply in the host but also releases some byproducts.
  • These byproducts may be toxic or non-toxic to host.

3.   Etiological agent

  • The etiological agent may be the causative agent of a disease
  • It may be an opportunistic pathogen
