Viruses

Vaccine

Provide acquired immune response that look like pathogens but are weakened or killed and do no longer cause illnesses

Inactivated vaccines

Pathogens that are killed by chemical, heat or radiation and require booster shot to maintain immunity.

Attenuated Vaccines

Active pathogen that is changed or weakened and is growing in a new host. Most require one dose.

Antiviral drugs

Another way to fight viruses. They usually prevent viral replication and are useful to fight viruses that vaccines are less effective

What are the 2 main cycles a virus use to reproduce

Lytic and Lysogenic

Lytic

Lytic viruses are made quickly and DNA does not enter chromosome.

Lysogenic

Lysogenic viruses are made after a little dormant period after which the DNA enters bacteria chromosome. Conditions change to trigger viral replication and release by lytic enzymes

Living viruses

They have nucleic acids (DNA or RNA), they reproduce, contain protein and cause disease

Non living

Non cellular, no metabolism or energy outside host cell, require a host of cell to reproduce

All virus have:

Genetic material and Caspid

Some virus have:

Lipid envelope

Amoebozoa

Supergroup of amoeba and slime mould

Excavata

Supergroup of euglenoids and zooflagellate

SAR

diatoms, sporonzoans, cliliates, dinoflagellate
