Microbiology
The specialized area of biology that deals with organisms too small to be
seen with the naked eye
6 major groups of microorganisms
1. Bacteria
2. Algae
3. Protozoa
4. Helminths
5. Fungi
6. Viruses
What do microbiologists study?
- 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?
1. Medical microbiology
2. Public Health microbiology and Epidemiology
3. Immunology
4. Industrial Microbiology
5. Agricultural Microbiology
6. Environmental Microbiology
Medical Microbiology
Study of microbes as they relate to medicine, deals with microbes that
causes disease in humans and animals
What are the in vitro and in vivo techniques in cultivating viruses?
In vivo methods: viral cultivation in lab animals
or embryonic bird tissues
In vitro methods: viral cultivation in cell or tissue
culture
What is the difference between a prion, satellite virus, and a viroid?
,• Prions
- Distinct abnormal protein fibrils deposited in brain tissue of affected
animals
- Common feature of spongiform encephalopathies
• Implicated in chronic, persistent disease in humans and animals
• Brain tissue removed from affected animals resembles a sponge
• Creutzfeldt-Jakob Disease (CJD)
• Affects the central nervous system of humans and causes gradual
degeneration and death
• Several animals are victims of similar diseases
• Satellite viruses
- Dependent on other viruses for replication and contains only genetic
material
- Adeno-associated virus (AAV)
• Originally thought that it could only infect cells infected with the
adenovirus
• Now found to infect cells infected with other viruses or had their DNA
disrupted through other means
• Viroids
- Virus-like agent that parasitizes plants
- About one-tenth the size of an average virus
- Composed only of naked strands of RNA
- Significant pathogens in economically important plants: tomatoes,
potatoes, cucumbers, citrus trees, and chrysanthemums
Name several diseases that are caused by a virus.
, Most common cause of acute infections that do not result in hospitalization
- Colds, chickenpox, influenza, herpes, warts
• Viral infections that only occur in certain regions
- Dengue fever, Rift Valley fever, Yellow fever
Can antibiotics target viral infections? Explain your answer.
No, because:
• Viruses mutate at a rapid rate
• Scientists focus on developing vaccines against viruses since few antiviral
drugs are available and antibiotics are ineffective
• Interferon (IFN)
- Naturally occurring human cell product
- Used with some success in treating viral infections
Public Health Microbiology and Epidemiology
Monitor and control the spread of disease in communities. USPHS, CDC, WHO
Industrial Microbiology
- Use of microbes to manufacture important compounds
- Safeguards our food and water
- Also includes biotechnology
- Ranges from bread making to gene therapy
