Microbiology Lab | The Capsule Stain

The video tutorial explains the concept of capsule staining in microbiology, focusing on the role of bacterial capsules in adhesion and immune evasion. It uses a hip replacement example to illustrate how capsules help bacteria form colonies on metal surfaces. The tutorial describes the negative staining technique, where the capsule appears as a halo around the bacteria. It also guides on identifying capsules in micrograph images, emphasizing that the capsule itself is not stained. The species Enterobacter cloacae is mentioned as an example studied in the lab.
