Which of the following types of pathogens can only reproduce itself if it atakes over host cells?

- fungi

-bacteria

-virus

-protozoa

A virus. Nasty little things. It will take over host cells, and lay copies of itself inside the host. The copy viruses grow and become stronger, not being able to be seen by the white blood cells that protect our immune system. Then those copies break out of the host and repeat the process.
