Handling human blood in the lab requires special safety procedures which are outlined in this video.

This video provides a basic introduction to chemistry. The periodic table of elements, atomic structure, and chemical bonding are covered.

The video is intended as an introduction to Human Anatomy and Physiology I. Basic terms are defined, the principles of complementarity and homeostasis are described, and regional terms are introduced.

This video reviews the structure, function, and formation of bacterial endospores. The medical significance is briefly touched on. Bacterial endospore staining is shown.

This video demonstrates the Gram staining procedure and explains the relationship between this differential stain and the cell wall structure.

This video demonstrates the procedures for making a bacterial smear, performing a simple strain, and using the oil immersion lens on the microscope. Common bacterial cell morphologies and arrangements are also described.

This video describes tools and demonstrates basic procedures used in the microbiology lab. Media, loop / needles (disposable and reusable) are described. Labeling, incubating, Bunsen burners, aseptic transfer basics are demonstrated.

This video demonstrates the streaking plating technique for bacterial colony isolation. The theory and trouble shooting is included.

This video provides a brief history of the emergence of SARS-CoV-2, the structure of coronaviruses, and a contrast of the coronaviruses that infect humans. The statistics sited in the video are from January 2022.
