and he observed that these bacteria had the smooth capsules characteristic of the S strain. Based on these observations, Griffith hypothesized that a chemical component from the virulent S cells ...

The type VI secretion system (T6SS) is a sophisticated, contact-dependent nanomachine involved in interbacterial competition. To function effectively, the T6SS must penetrate the membranes of both ...

Both stains differentiate between bacteria chemically. The two staining techniques of Lab 4 differentiate by structural differences to tell one type from the other. The first stain (the endospore ...
