Bacteria
Bacteria are single-celled microorganisms that thrive in many different types of environments. Some varieties live in extremes of cold or heat. Others make their home in people's intestines, where they help digest food. Most bacteria cause no harm to people, but there are exceptions.
Viruses
Viruses are even smaller than bacteria and require living hosts — such as people, plants or animals — to multiply. Otherwise, they can't survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus.

There are more than 30 types of Staphylococcus, or staph, bacteria. Most staph infections are due to the species Staphylococcus aureus (S. aureus). This bacteria lives on the skin or inside the nose and can enter the body through an open wound.
How does a virus replicate?
In order to replicate, they must enter the cells of a living organism, such as a human or an animal. A viral infection happens when a virus gets into the body and invades healthy cells. The virus then uses the cell’s machinery to make copies of itself. This process can kill, damage, or change the cells.
