Study Notes
Virus Structure
- A virus consists of a protein coat (capsid) surrounding a core of genetic material (DNA or RNA).
Types of Viruses
- There are two main groups of viruses based on their genetic material: DNA viruses and RNA viruses.
Viral Envelope
- The viral envelope is a lipid bilayer derived from the host cell membrane, and it contains viral glycoproteins.
Size of Viruses
- The size of a virus is typically measured in nanometers (nm).
Shapes of Viruses
- Viruses can have various shapes, including helical, icosahedral, complex, and enveloped shapes.
Latency
- During latency, virus multiplication is inactive.
Smallpox Vaccine
- The vaccine for Variola (smallpox) was created from the Cowpox virus.
Cytopathic Effect (CPE)
- The Cytopathic Effect (CPE) is used to characterize infection by observing the changes in host cells in a laboratory culture.
Herpes Simplex-1
- Herpes simplex-1 induces lesions on the face and mouth.
- Herpes simplex-1 is transmitted through skin-to-skin contact.
- Herpes simplex-1 infections are characterized by vesicular lesions.
- Latency location for HSV-1 is in the trigeminal ganglia.
Herpes Simplex-2
- Herpes simplex-2 causes lesions in the genital and anal areas.
Complications
- Herpes simplex infection leads to severe complications in immunocompromised individuals, such as HIV patients and organ transplant recipients.
Varicella Zoster
- Varicella zoster is the virus that causes chickenpox and shingles.
Cytomegalovirus (CMV)
- Cytomegalovirus (CMV) sero-prevalence in the world amounts to around 80-100%.
