Parasite Obligate

Obligate parasites are organisms that live at the expense of another organism, but cannot survive without it. They can be both harmful and beneficial for the owner.

Obligate parasites can be divided into two groups:

1. Viruses are obligate parasites that do not have their own metabolism and depend on the host for reproduction. Some viruses can cause serious illness in humans and animals, such as HIV and hepatitis C.

2. Bacteria are also obligate parasites, but they can survive on their own and reproduce outside the host. Some bacteria cause infections in humans, such as staph and E. coli.

An obligate parasite is an organism that cannot survive without another organism. It depends on its host for nutrition and reproduction. Obligate parasites can be harmful or beneficial to their host, depending on how they affect the host's health.
