Document Summary
Symbiotic bacteria in gut play a role in metabolism. Failure for immune system: incorrect response: cannot distinguish self cells, autoimmune, overactive response: allergies, overreaction to an antigen , lack of response: aids, hiv, immunodeficiency disease. Disease sometimes deadly such as halting your breathing. Envelope phospholipid, protein from host cell membrane. Cannot be killed by antibiotics some can be treated with antiviral drugs. Virus binds to membrane receptor triggers endocytosis of. Virus envelope fuse with host cell membrane to deposit virus rna into the host cytoplasm. Virus rna takes over host cell resource. Assembled and released to infect other cells: virus causes host cell to burst to release virus particles into, virus particles surround themselves with host cell the extracellular fluid ecf membrane and bud off from host cell. Chicken pox virus hides in the cell but hiv and oncogenic viruses (cancer) incorporate their dna into the host cell dna to replicate.
