Bacteria are classified as either Gram-negative or Gram-positive based on their cell wall structure—Gram-negative bacteria have a thick layer of protection, making them difficult to kill. Most ...

This medium is both selective and differential. The selective ingredients are the bile salts and the dye, crystal violet which inhibit the growth of Gram-positive bacteria. The differential ingredient ...

Today you will finish up testing for both gram positive and gram negative organisms. There are few tests that can be read immediately that we call rapid tests. These are often useful initial steps to ...

In gram-negative bacteria, the most common mechanism of resistance is the hydrolysis, or breaking apart, of the antibiotics by enzymes referred to as the beta-lactamases. There are two broad classes ...

Infections by multidrug resistant organisms (MDROs) are a global health threat with a worrying increasing trend. In fragile ...
