In order to kill microorganisms, antiseptics can be used to make this possible. The antiseptic can be effective in inhibiting the growth of the microorganism especially on the outer portion of the body but there are also some that can be consumed so that microorganisms inside the body can also be killed.

Sterilization is different because it does not make use of chemicals in order to make the object or the person free from bacteria. This can actually eliminate every living thing that is in a certain surface area. Thermal disinfection does not make use of chemicals too. Rather, heat is used in order to sterilize different medical equipment and tools to make them safe to use again.

For example, a tick may live on a dog for the longest time because this means that the tick will have access to the dog’s blood, which it needs to survive. These two need to depend on other organisms to survive. If they would not find anything to latch on, their end is inevitable.
