Viruses
- Virus
- An obligate, intracellular parasite
- Obligate intracellular parasite
because viral replication
depends completely on host
cell
- Obligate intracellular parasite
because viral replication
depends completely on host
cell
- Viruses are not:
1. Cells or
made up of cells
2. Cannot
manufacture
own ATP, Amino
Acids,
nucleotides, and
protein
- Virions: Infectious
viral particles (Basically a
whole parasite,
because they are not
considered
organisms)
- Epidemic: Disease that rapidly
infects a large number of
individuals over a widening area
Ex. Native Americans dying from
smallpox
- Pandemic: an epidemic that is worldwide
Ex. 1918-1919 Influenza Outbreak 50
million people died
- HIV (Human immunodeficiency virus)
- AIDS (Acquired immune deficiency syndrome)
- HIV attacks the human immune
system, specifically the Helper T
cells. HIV kills the Helper T cells
which will cause the human to not
be able to fight off pathogens
- Young children will typically die of HIV, but
older (late teens and up) usually will die of
AIDS
- AIDS (Acquired immune deficiency syndrome)
- HIV (Human immunodeficiency virus)
- Pandemic: an epidemic that is worldwide
Ex. 1918-1919 Influenza Outbreak 50
million people died
- Virulent:
Viruses that
tend to
cause severe
disease
- Viruses are very small (0.1
micrometers) Eukaryotic cells
are roughly 7 micrometers
- Epidemic: Disease that rapidly
infects a large number of
individuals over a widening area
Ex. Native Americans dying from
smallpox
- An obligate, intracellular parasite
- Lateral Gene Transfer:
Viruses can introduce
foreign genes into cellular
genomes by picking up
genes from one organism
and shuttling them to
another
- 5-8% of human genome
is remnants of viral
genome
- 5-8% of human genome
is remnants of viral
genome
