Specialization
-
Agricultural microbiologists
Study microbes that affect cultivation, fertility, health, and spoilage
of agricultural products. Some are veterinarians who figure out ways to
improve livestock health.
-
Biotechnologists/biochemical engineers
use genes to modify microorganisms and use these modified organisms to
create products like medicine, disease-resistant food, and biological agents
that fight pollution.
-
Cell biologists
Study the molecules in cells and the effects of outside molecules on cells.
For example, they study how skin cells interact with certain bacteria and
how cancer cells grow.
-
Immunologists
Study how the body fights disease and how bacteria grow, are nourished,
and evolve.
-
Mycologists
Study molds, yeasts, and mushrooms. Some use molds and yeasts to produce
antibiotics or other medicines. Others work in the agricultural industry,
developing ways to fight fungal plant diseases.
-
Parasitologists
Study the life cycle and evolution of parasites, organisms that depend
on other organisms for survival.
-
Epidemiologists
Study outbreaks of disease to learn their causes and the best ways to
fight them. Some study rare diseases or diseases in remote parts of the
world.
-
Virologists
Study how viruses evolve. Virologists often study newly identified types
of viruses or viruses for which vaccines or cures have not yet been
developed.
-
Marine microbiologists
Study micro-organisms that live in the ocean and how they affect the
marine environment. Some look for new ways to fight pollution from oil spills.
