Medical biology, the massive set of biology that's applied to drugs, may be a branch of life science involved with the interference, identification and treatment of infectious diseases. additionally, this field of science studies varied clinical applications of microbes for the development of health. There area unit four styles of microorganisms that cause infectious disease: bacterium, fungi, parasites and viruses, and one style of infectious supermolecule known as particle. A medical life scientist studies the characteristics of pathogens, their modes of transmission, mechanisms of infection and growth. mistreatment this data, a treatment is devised.
