Let’s be honest, studying microbiology can seem pretty daunting. With a multitude of microorganisms to classify, an array of toxins and enzymes to remember, and a seemingly endless list of bacteria, viruses, fungi, and parasites with perplexingly similar names, it’s no wonder that many medical students find themselves overwhelmed.
With words like clostridium botulinum, pseudomonas aeruginosa, and corynebacterium diphtheriae, it’s hard to even know how to start remembering the content. If you’ve ever grappled with these concerns, you’re not alone. In this blog, we’re diving headfirst into how to study microbiology, unraveling its complexities, and shedding light on the importance of understanding this subject.
What do you learn in microbiology?
Microbiology encompasses a range of topics, including bacteria, viruses, fungi, parasites, and prions. To give you a sense of the scope, let’s look at the USMLE® outline for Microbial Biology:
- Microbial biology
- Microbial identification and classification, including principles, microorganism identification, and non-immunologic laboratory diagnosis
- structure (eg, cell walls, composition, appendages, virulence factors, extracellular products, toxins, mechanism of action of toxins)
- processes, replication, and genetics (eg, metabolism, growth, and regulation)
- antibacterial agents (eg, mechanisms of action on organism, toxicity to humans, and mechanisms of resistance)
- structure (eg, physical and chemical properties, virulence factors)
- processes, replication, and genetics (eg, life cycles, location of virus in latent infection) oncogenesis
- antiviral agents (eg, mechanisms of action on virus, toxicity to humans, and mechanisms of resistance)
- structure (eg, cell wall, composition, appendages, virulence factors, extracellular products, toxins, mechanisms of action of toxins)
- processes, replication, and genetics (eg, asexual vs. sexual, metabolism, growth)
- antifungal agents (eg, mechanisms of action on fungus, toxicity to humans, and mechanisms of resistance)
- structure (eg, appendages, macroscopic features, and virulence factors)
- processes, replication, and genetics (eg, life cycles, metabolism, and growth)
- antiparasitic agents (eg, mechanisms of action on parasite, toxicity to humans, and mechanisms of resistance)
What is microbiology the study of?
Microbiology is the study of microorganisms, which are tiny, often microscopic life forms that exist all around us. Microbiology delves into the world of these tiny creatures, exploring their structure, genetics, physiology, and their interactions with other living organisms and the environment.
In addition to studying the individual microorganisms themselves, microbiology also examines how they interact with their hosts, how they can be identified and classified, how they cause diseases, how to diagnose infections, treatment options, and strategies for preventing the spread of infectious agents. Our Microbiology Core books keeps it high level, and then you can dive more into the other topics in the Infectious Disease section.
For medical students, microbiology is about understanding the roles of different microorganisms in the context of medicine for your future patients. Whether it’s diagnosing a bacterial infection or virus, without a solid foundation of microbiology, you might not have the knowledge to properly diagnose your patients.
Is microbiology a hard class?
Microbiology is often considered one of the toughest subjects in medical school. Reddit r/medicalschool threads and Student Doctor Network (SDN) threads are filled with discussions on the topic. The reasons for its difficulty are clear: the extensive content, the need to apply it clinically, and the fact that missing crucial concepts can hinder your understanding of other medical disciplines down the line.
The sheer amount of information can be overwhelming. For example, for each microorganism, students need to learn about its structure, pathogenesis, clinical manifestations, diagnostics, treatments, and prevention.
Medical students need to be able to apply their basic science knowledge of microbiology to clinical scenarios. Understanding how a microorganism’s biology translates into clinical symptoms, diagnostic tests, and treatment strategies are essential.
Why is microbiology important?
Despite its reputation as a challenging subject, microbiology is undeniably important. It plays a critical role in medicine and healthcare, as demonstrated by the USMLE® Step 1 content outline, which assigns a significant weight to microbial biology, 10-15% to be exact. Understanding microbiology is essential for diagnosing and treating diseases.
Plus, microbiology knowledge is foundational for other medical school subjects. For example, when you get to pharmacology, you’ll use microbiology knowledge when selecting appropriate treatments, and in pathology you’ll use it to understand the tissue response to infections.
How to study for microbiology in med school
Effective microbiology study involves using the right resources, getting a comprehensive foundation, using patient cases to review, and breaking up learning into manageable chunks. Let's take a look:
Find the right resources
For this part, the Microbiology Medical Student Core book is going to be your best friend. Unlike a lot of the other microbiology tomes written for microbiologists or students interested in biotechnology who need way more detail than you need for your medical practice, the microbiology Core book breaks down only what you need to know for the USMLE® exams.
In 37 pages, the microbiology Core book covers the basics of what you need to know in manageable chunks. Within the content there’s 33 images, illustrations, and charts that make the content more digestible. Microbiology content is also referenced throughout other books in the Core for a more comprehensive review.
Use this microbiology textbook as a study aid
To succeed in microbiology, it’s crucial to have a dedicated microbiology textbook as your study companion. Consider using a resource like the Medical Student Core Microbiology book, which provides comprehensive coverage of the subject. An effective study technique is “chunking” information—grouping related concepts together to make them easier to learn and remember. For example, organize microbiology topics by category and subcategory.

Get a comprehensive overview of microbiology
Because there is so much to memorize in Microbiology, it requires a strategic study approach. Begin by understanding the fundamental concepts. Know the basic structure, reproduction, and general mechanisms of pathogenicity for each category. Try to get the basics down pat before moving on. This foundational knowledge will serve as your anchor as you delve deeper into the subject.
This microbiology textbook “chunks” up the information by topic, and then by subtopic, to make it easier for you to learn and memorize. For example, the Parasites section begins with an overview, then splits parasites into protozoa and helminths. Helminths are split into cestodes, trematodes, and nematodes. Then we go into the oncogenesis and antiparasitic agents for parasites.
Use patient cases to study
Why did you choose to study medicine? Most students would probably say to help people. The best way to keep your mind focused on your why is to imagine yourself in your role as a physician helping patients. And, the best way to do that is by answering Qbank+ questions.
Try it out with this Step 1 Qbank+ question. Imagine yourself in the exam room with this 19-year-old woman, how would you answer?
