4.7 Viruses : The Enemy Within By: Steffany Copeland
Viruses are life mimicking particles • Latin word for poison • Viruses are nonliving • Viruses cannot reproduce by themselves • Viral genomes can be single or double stranded • Viruses range from .027mm-0.03mm • Obligate intracellular parasites • The entire infectious virus particle as a whole- virion
Viruses hosts • Bacteria • Animals • Humans • Plants • Fungus • Insects
Nucleic acid Protein coat or capsid Envelope Tail Tail fibers End plate Viral Structure
Lytic viral growth cycle of Bacteriophage • Adsorption • Penetration • Replication • Assembly • Release
Lytic replication cycle of rabies virus, an enveloped virus with a single-stranded RNA genome
Virions of enveloped viruses are released by budding from an infected virus
Rabies virus can be deadly • Rabies virus travels slowly to the CNS where it replicates and then travels to the salivary glands where it replicates again • There are 2 types of rabies: Furious Rabies and Dumb Rabies
