Science advancements has helped us answer mysteries of the world and help cure diseases. Bacteriology is the study of bacteria helped scientists find the cause of source for diseases‚ explanations‚ and possibly cures for disease. In the early 1900’s many people were getting sick from typhoid fever in the united states‚ this led to an investigation and virtually a whole new explanation of diseases spreading thru "healthy carriers."
