Does Bacteria Require A Living Host. Web the usual answer to this question (and usually for the purpose of passing your biology gcses) is that viruses are not alive, because they do not complete all of the seven life. Web bacteria and viruses can live outside of the human body (for instance, on a countertop) sometimes for many hours or days.
Web other kinds of bacteria (as well as parasites and viruses) can make us quite ill if they invade our bodies. Web many pathogens require a living host to survive, while others may be able to persist in a dormant state outside of a living host. Most of the bacteria found in the human gut is anaerobic bacteria.

Because of these differences, bacterial and viral infections are. Escherichia coli occurs in diverse forms in nature, ranging from commensal strains to those pathogenic on human or animal hosts. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of earth's crust
Web Biology, Health Image Virus Viruses Are Microscopic Biological Agents That Invade Living Hosts And Infect Their Bodies By Reproducing Within Their Cell Tissue.
Bacteria and viruses can live outside of the human body. Web for example, rickettsia bacteria are classified as living but, like viruses, can multiply only within other cells. Additionally, viruses technically do not require oxygen as they are.
But Having Infected One Host, All.
Web the usual answer to this question (and usually for the purpose of passing your biology gcses) is that viruses are not alive, because they do not complete all of the seven life. Unlike bacteria, many of which can be grown on an artificial nutrient medium, viruses require a living host cell for replication. All living things, in fact, rely on other living things.
