Immunology (Body’s defense system, Host-Parasite Interactions, Immune system function) Definition: Microbiology - Branch of biology that studies microorganisms and their effects of living organisms. It was first directed towards the effects of microorganisms, but during the last 100 years has shifted to their physiology, biochemistry and genetics. It is a branch of biology dealing esp. with microscopic forms of life (i.e. fungi, virus, bacteria) Medical Microbiology - study and effects on these microorganisms on humans; Microscopic organisms and microbes. Characteristics : Oval; elongated; hair-like; spiral; spherical; etc. Biologically Distinct: such as gram positive (blue/violet) and gram negative (red/pink) etc. Evolutionary succession: (Refer to pictures on original handout) III.
