The original lifeform on earth was RNA.
RNA reverse trandscips into DNA.
DNA -->Protein --> Protein world.
HIV can reverse transcript into viral DNA.
A sloppy job is done so HIV mutates frequently.
Flu is an RNa virus.
Slight changes is = Antigenic drift.
It takes six month to make enough flu vaccine for
everyone.Nelghi bodies = Includsion bodies in rabies.
First thing that happens in lytic cell is it kills host cells
chromosomes.
Epstein-barr virus causes mono.
Esptien barr virus - First herpes dieases studied in class
Cytomegavirus = Second herpes diseases studied in class
There are no other animal hosts for small pox
CMV(Cytomegalovirus) can cause birth deffect/
Epstien barr causes Burkett's lymphoma.
Virses depress immunity.
KaposkiSarcoma - Rare, found in elderly men of metterian
decent.
Herpes 8 causes Kaposki's Sarcoma a rare maligant blood and
blood vessel cancer.
Pigs are the melting pot.
Antigen shift - When avian flu+Human flu
Rubella - German measles
Chicken pox, - Live atteunated vaccine
Shingles vaccine - Boosters, livew attenunated.
1. Scientists classfiy viruses by the type of genetic material that
makes uyp the viral gene.
2. Virus is poison in Latin
3. Interest has increased in phasge therapy due to the amount of
resistant bacteria.
Danger - Can harm microbiota and make bacteria more lethal
Pro - Living natural defense against germs.
4. Transduction - Transfers DNA from first host into a new
host.
5. Neoplasim - Uncontrolled cell division.
Tumor - Mass of Neoplastic cells
Benign - Not spreading and not harmful
Malignant - Spreading and harmful
Metaasis - Moving to other tissues
Cancer - Maligant tumor
5. Proctoncogees- Genes that play a part in cell division
Oncogenes - Active protoncgenes
6. Three ways viruses can cause cancer
I. Carry copies of oncogenes
2. Promote oncogenes already in the host.
3. Interfere with normal tumor repression.
7. Cell culture - Cells isolated from an organism and grown on
a medium
Diploid cell culture - Created from embroynic animal, plant, or
human cell. 100 cell generations.
Continoous cell divison - Created by tumor cells and never end.
7. Viroids - Small circular pieces of RNA pathogenic in plants.
They are similiar to RNA viruses but they lack capsids.
8. Kuru, Cretz-jacobs disease, Hepatitis D and Bovine
spongiform encephalitis are caused by viroids.
9. Viruses are not alive.
1. Ocular herpes - The HSV in the trigeminal ganglion travels
down the opthalamic brand of the trigeminal nerve.
2. Whitlow - Inflammed blister on the finger caused by HSV
getting into a cut. Kids who suck their thumb and healthcare
workers who could come into contact with the virus are at risk.
3. Neonatal herpes is a herpes babies can get when the virus
crosses the placenta or from blisters in the birth canal.
30% mortality in oral or cutenous.
80% mortality if the CNS is affected.
Pregnnt women should have C-sections if they have an
outbreak during birth time.
4. Herpes Zooster = Shingles.
5. Dermatone - Shingles lesions ina band.
6. Varicella-zooster virus(VZV) causes shingles. Babies can not
be vaccinated until their one year old.
It's hard to prevent exposure to VZV because viruses are shed
before signs appear.
4. Kids should not use aspirin to treat viral disese due to Reye's
sndrome.
Reye's syndrome - Encep[alophy, fatty infiltration of organs,
rash, vomiting, confusion, coma, serizures, respitory distress
and death.
8. Virema - Virons in the blood.
Tertaogens = Cause birth defects
9 HSV-6 can cause multiple scelerosis.
10. Kaposi Sarcoma - Rare and maligasnt cancer of blood and
blood vessels. HSV-8 causes it. It occurs in AIDS patietnts.
11. Papilloma = Wart
1. Rhinovirus causes the common cold.
2. Direct person to person contact is most common mode of
transmission of colds. Antispesis is most common preventative
measure.
3. Post-polio syndrome - Cripppling deteroation of polio-affeted
muscles occuring 30-40 years after polio in 80% of patients.
4. Cossachie B virus could be the cause of Diabeates type one
akja Diabetes melltius.
5. Kaplik's Spots - Lesions on the roof of the mouth, indicative
of measles.[/size]
