This Unit is quiet interesting: microorganisms. We are not just talking about bacterias: protozoa and viruses are going to be also studied. Some bacterias are harmful: some others may be symbionts of us. Remember all the studied concepts such as antibiotics, vaccines, vectors or booster dose. This exam will be more dificult than the others. Please don´t forget to complete your notebook and...MERRY CHRISTMAS!!!
