6 major groups of microorganisms - CORRECT ANSWER -1. Bacteria
2. Algae
3. Protozoa
4. Helminths
5. Fungi
6. Viruses
What do microbiologists study? - CORRECT ANSWER -- Cell structure
- Growth and Physiology
- Genetics
- Taxonomy and evolutionary history
- Interactions with living and non living environment
What are the 6 different branches of study in microbiology? - CORRECT ANSWER -1. Medical
microbiology
2. Public Health microbiology and Epidemiology
3. Immunology
4. Industrial Microbiology
5. Agricultural Microbiology
6. Environmental Microbiology
,Medical Microbiology - CORRECT ANSWER -Study of microbes as they relate to medicine, deals
with microbes that causes disease in humans and animals
Public Health Microbiology and Epidemiology - CORRECT ANSWER -Monitor and control the
spread of disease in communities. USPHS, CDC, WHO
Industrial Microbiology - CORRECT ANSWER -- Use of microbes to manufacture important
compounds
- Safeguards our food and water
- Also includes biotechnology
- Ranges from bread making to gene therapy
- Microbes can be used to create large quantities of substances such as amino acids, beer, drugs,
enzymes, and vitamins
Agricultural Microbiology - CORRECT ANSWER -- Deals with the relationships between microbes
and domesticated plants and animals
- Plant specialists focus on plant diseases, soil fertility, and nutritional interactions
- Animal specialists work with infectious diseases and other associations animals have with
microorganisms
Immunology - CORRECT ANSWER -Studies a diverse areas such as vaccination, blood testing,
and allergy. Immunologists investigate the role of the immune system in cancer and
autoimmune diseases
Environmental Microbiology - CORRECT ANSWER -Studies the effect of microbes on the earth's
diverse habitats.
Example- aquatic microbiology, soil microbiology, geomicrobiology, and astrobiology
,eu-kary means? - CORRECT ANSWER -true nucleus; cells with a nucleus are classified as
eukaryotes
Pro-kary means? - CORRECT ANSWER -Pre-nucleus; bacteria and archaea do not have a nucleus
and have been traditionally classified as prokaryotes
What is a microbe? - CORRECT ANSWER -A microorganism
How are biology and microbiology different? How are they similar? - CORRECT ANSWER -Biology
is concerned with all the different scales of size that microorganisms exist on, but many fields on
biology are concerned with more complex organisms such as mammals. Microbiology is
concerned specifically with smaller, individual organisms. Microbiologists might be concerned
with something as big as a bacteria, and they do study systems, such as the immune system, but
generally they focus on smaller individual organisms. They are similar because they both study
organisms, just on different scales.
Bacteria - CORRECT ANSWER -- Unicellular microorganisms
- Some cause human, animal, or plant diseases; others are beneficial.
- Prokaryotic
Algae - CORRECT ANSWER -- Unicellular microorganisms
- Prokaryotic
- Food or water borne
- Reproduce Asexually
- Photosythetic
Protozoa - CORRECT ANSWER -- Unicellular
- Eukaryotic
, - Live independently or as parasites
- Mostly found in soil or water
Helminths - CORRECT ANSWER -- Multicellular
- Eukaryotic
- Worms
Fungi/Yeast - CORRECT ANSWER -- Eukaryotic
- Multicellular
- Protists characterized by the absence of chlorophyll and by the presence of a rigid cell wall
Medical Microbiology - CORRECT ANSWER -- Deals with diseases of humans and animals
- Study the way microorganisms cause disease
- Example: A Microbiologist at the CDC may examine a culture of the influenza virus in order to
understand why is is so harmful
Public Health Microbiology & Epidemiology - CORRECT ANSWER -- Monitor and control the
spread of diseases in communities
- CDC, USPHS, & WHO
- Example: Epidemiologists conduct interviews as a part of the effort to curb the cholera
epidemic in Haiti
Immunology - CORRECT ANSWER -- Studies the web of protective substances and cells produced
in response to infection
- Vaccination, blood testing, and allergy
- Immunologists investigate the role of the immune system in cancer and autoimmune diseases
- Example: Immunologists freeze dry samples of infectious diseases
