Document Summary
Viruses that target bacteria could help give antibiotics a boost. Viruses are cell specific. (a uti virus will never give you a liver infection). Tropism cells and tissues of a host that support growth of a virus/bacteria. Viruses bind to host cells via receptors. These receptors are not meant to be used by viruses. Bacteriophages are used for cloning in the lab. Viruses are vehicles for moving genes around. They move genes from one host to another and they can leave their own genome behind. All viruses play a significant role in the carbon balance and in the global recycling of nutrients. To put it simply, a virus is the simplest life form or the most complex lifeless molecule! Minimally consist of genetic/chromosomal material (dna/rna) enclosed by a protein coat or capsid. Viruses must infect a host cell to replicate and produce. When viruses are not in a host, they are called virioms.
