Microbiology is the branch of biology that focuses on the study of microorganisms and their relationship to disease processes by describing their characteristics (e.g., species, structure, virulence factors, etc.). In the 20th century, infectious diseases were the most significant causes of morbidity and mortality. After the advent of antibiotics, these diseases became significantly less prevalent and less deadly. They are, however, still encountered in clinical practice, so a competent physician must have a good grasp of the most common pathogens in their area of work.

Not all microorganisms are pathogens, and some are actually beneficial to humans. Microbiology provides a way to understand the difference between harmful and helpful organisms. Studying microbiology will help you gain a clearer understanding of the pathophysiology of which the pathogens are a part, effective pharmacological therapies, and mechanisms of resistance.

The most effective way to master microbiology is to combine different learning modalities. First, do a deep dive into the topics with video lessons hosted by experienced educators. Next, plunge into Lecturio’s comprehensive Concept Pages. Then, apply what you’ve learned in practical situations by answering clinical case questions in the Qbank. Finally, make sure you retain information long term by regularly reviewing your knowledge with Spaced-Repetition quizzes.
