Your question resembles an unsolvable riddle.

I am assuming you are talking about an animal host. (Giving a disease to a healthy person would be unethical.) The methods vary based upon what type of disease it is and how it is transmitted.

For something like rabies the Spinal cord is saved, purified for the virus, and injected into a new dog. HIV they use a blood transfusion from chimp to chimp.

Many bacteria and fungus can be grown in a petri dish and then injected into the animal.
