Hardest Microbiology Quiz Trivia: Test! - Quiz

Do you like researching? Have you ever thought about how many microorganisms reside inside and outside your body? If you feel so, you are a microbiology student who loves to investigate everything around the environment. Microbiology is a broad area of science that includes bacteriology, parasitology, and many more. This quiz will test your knowledge and understanding of the different microorganism's roles and functions.
