      Hi mnormanly,
      Its necessary to beat bacterias which are bad for health. Till date we are using antibiotics to kill them but bacteria are very good in finding ways to survive. They develop resistance to the antibiotics and then they can easily grow and cause disease even int he presence of antibiotic. Many researchers are using bacteriophages to kill bacteria (virus that can kill bacteria).
      But some bacteria are good for us and you don’t have to kill them for example the bacterias which help us in digestion 🙂

      Bacteria are some of my favourite creatures as they can break down oil and chemical spills in underground aquifers and you can even find out what food they like to help them clean up chemical spills faster and protect our drinking water. Most bacteria are really useful to humans, its only a tiny minority are harmful!
