A host.
host
An organism that can provide a source of energy for a virus or another organism is called a host. The host organism can provide resources and nutrients necessary for the growth and reproduction of the virus or another organism that depends on it for survival.
The answer to this question is a host! A host could be a host cell which a virus uses to reproduce and create more viruses to get you sick!
A parasite is any organism that lives on or in another organism, not necessarily a fungus, virus or bacteria.
A virus is a small infectious agent that can only replicate inside the living cells of an organism. A host is an organism that provides nourishment and a habitat for another organism. A parasite is an organism that lives on or inside another organism (the host) and benefits at the host's expense.
A host organism is one that provides a source of energy or a suitable environment for a virus or another organism to live and thrive. The host may not always benefit from this relationship and can sometimes suffer harm from the presence of the virus or other organism.
bacterica is one of them, virus is another and I'm not sure on the rest
A parasite is an organism that lives in or on another organism (the host) and benefits from the relationship at the expense of the host. Bacteria and viruses can both be parasites, depending on their interactions with the host organism.
rabies, but that's kind of vise-versa don't you think?
No, a virus cannot catch a virus and become ill. A virus is a shell of protein containing DNA. A virus works by getting into a cell and "reprogramming it" to multiply and start to take of the organism. A virus cannot infect another virus because viruses are not cells themselves.

It will destroy cells in the organism
