Online Microbiology Courses for Credit

There are many free online courses offered online that can be completed at a self-directed pace, though they do not award grades or academic credit. Students looking for an online option that can be applied to a degree program might want to consider the Biology 103: Microbiology course available from

The lesson transcripts allow students to work at their own pace, as do the videos and self-assessment quizzes available to registered members. These course materials can be used to earn real college credit for far less time and expense than it would take to complete a class through your typical postsecondary institution. Some of the chapters included in the microbiology course are listed below:

  • Microbiology Basics - Review cell structure before exploring the characteristics of bacteria, protozoa, algae and fungi.
  • The Disease Process - Examine the types and causes of microbial infection and disease as well as routes of transmission. Differentiate between endemics, epidemics and pandemics.
  • Fungal Infections - Instructors cover infections caused by Cryptococcus, Histoplasma capsulatum, Candida albicans and other fungi.

Free Online Non-Credited Microbiology Courses

Massachusetts Institute of Technology

  • Environmental Microbiology includes lecture notes about biosynthesis and fueling, cell biology, genetics, metabolic diversity and applied environmental microbiology. It's recommended that students complete readings from the textbook Brock Biology of Microorganisms (10th edition) by Madigan, Martinko and Parker, which can be purchased through a link on the site. All available course materials can be downloaded as ZIP files. This free, non-credit course is also translated into Chinese.
  • Systems Microbiology covers such topics as genomics, microbial diversity and population dynamics. Some specific case studies on the course site include tuberculosis, plagues, vaccines and Helicobacter pylori. The course includes assignments and exams, which are downloadable as ZIP files from the course site, but they don't include solutions. Students can purchase the textbook Brock Biology of Microorganisms (11th edition) by Madigan, Michael and Martinko through the course website to fully learn from the course.

University of Wyoming

  • General Microbiology is broken into two types of classes - lectures and labs - and a site is included for each. The lecture site includes PDFs, while the lab site, called The Virtual Edge, includes lecture notes and lab instructions. Step-by-step video tutorials that teach students how to do the labs are available. Free downloads of the Shockwave Player and QuickTime are needed to view the video tutorials.

University of California - Davis

  • Introduction to Microbiology and Culture Techniques is a lecture given by a Ph.D. candidate at UC - Davis. It covers pathological microbiology topics that include blood, urine and tissue cultures; culture collection processes; gram stains and negative stains; and other staining procedures. The instructor also discusses viruses and fungi, including the H1N1 influenza.

Tufts University

  • Microbiology emphasizes pathobiology and covers topics such as malaria, enteric bacteria, normal flora and host parasite interactions. Lectures and student notes are included in the course. Recommended readings are taken from the textbook, Mechanisms of Microbial Diseases (3rd edition), by Schaechter, Medoff and Eisenstein, which would need to be purchased.
  • Pathophysiology of Infectious Diseases surveys such contagious illnesses as meningitis, pneumonia, tuberculosis and hospital infections. Students also study the role of microorganisms in chronic disease. Quizzes and exams, lectures and HIV case study questions are available. Additional readings are found in several recommended textbooks, which can be purchased separately.

Johns Hopkins University

  • Epidemiology of Infectious Diseases includes lectures and links to readings and an assignment. Some of the topics include an overview of microbiology, outbreaks and disease, lab diagnosis, molecular epidemiology and transmissions, with case studies that include hepatitis, HIV, malaria and acute respiratory infections.

University of Michigan

  • Infectious Disease / Microbiology was originally taught to first-year medical students at the school. Some of the topics covered in lectures include respiratory viruses, parasitology, HPV, HIV and biopreparedness. Student notes are available as well. Students can also download an interactive module on vaccines, which is available as a link on the site. All available course materials can be downloaded as a ZIP file, and as of December 2012, new materials were still set to be added to the course. Online students who would like to benefit from this course as much as possible can purchase two textbooks.
