Microbiology Exam #1 (Chapter
1,3,4,5,6)
Microbiology - Answer-The specialized area of biology that deals with organisms too small to be seen
with the naked eye
6 major groups of microorganisms - Answer-1. Bacteria
2. Algae
3. Protozoa
4. Helminths
5. Fungi
6. Viruses
What do microbiologists study? - 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? - Answer-1. Medical microbiology
2. Public Health microbiology and Epidemiology
3. Immunology
4. Industrial Microbiology
,5. Agricultural Microbiology
6. Environmental Microbiology
Medical Microbiology - Answer-Study of microbes as they relate to medicine, deals with microbes that
causes disease in humans and animals
Public Health Microbiology and Epidemiology - Answer-Monitor and control the spread of disease in
communities. USPHS, CDC, WHO
Industrial Microbiology - 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 - 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 - 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 - Answer-Studies the effect of microbes on the earth's diverse habitats.
Example- aquatic microbiology, soil microbiology, geomicrobiology, and astrobiology
,eu-kary means? - Answer-true nucleus; cells with a nucleus are classified as eukaryotes
Pro-kary means? - Answer-Pre-nucleus; bacteria and archaea do not have a nucleus and have been
traditionally classified as prokaryotes
What is a microbe? - Answer-A microorganism
How are biology and microbiology different? How are they similar? - 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 - Answer-- Unicellular microorganisms
- Some cause human, animal, or plant diseases; others are beneficial.
- Prokaryotic
Algae - Answer-- Unicellular microorganisms
- Prokaryotic
- Food or water borne
- Reproduce Asexually
- Photosythetic
Protozoa - Answer-- Unicellular
- Eukaryotic
- Live independently or as parasites
- Mostly found in soil or water
, Helminths - Answer-- Multicellular
- Eukaryotic
- Worms
Fungi/Yeast - Answer-- Eukaryotic
- Multicellular
- Protists characterized by the absence of chlorophyll and by the presence of a rigid cell wall
Medical Microbiology - 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 - 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 - 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
