Study Notes
Viral Infections
- Viral Acute Infections: The virus infects cells, causing disease, and is completely eliminated after recovery.
- Viral Latent Infections: Viruses replicate at lower levels, don't replicate widely, and have their genome in an episomal form.
- Vaccinations: Vaccines use whole inactivated organisms, stimulate immune responses, or contain specific viral antigens and immunoglobulins.
Viral Structure and Function
- Viral Capsid: Protects the viral genome and facilitates cell entry (in naked viruses).
- Glycocalyx (Biofilm): A protective layer, found on mycobacterial, assists immune systems in attacking bacteria.
- Viral Envelope: An outer covering of viruses; made of proteins, can have both bacterial and viral components.
Viral Life Cycle
- Viral Replication Cycle: Adsorption, penetration, uncoating, replication, assembly, maturation, release
- Abortive Viral Infection: Virus enters a cell, but the life cycle isn't completed.
Bacterial Infections
- Staphylococcus aureus: Can cause food poisoning, toxic shock, and soft tissue infections. It's a Gram-positive bacteria.
Antibiotics
- Antibiotics: Do not cure viral infections. Inhibit bacterial replication, not viral.
