How does yersina pestis get energy?

Yersinia pestis, the bacterium responsible for the plague, obtains energy through the metabolism of organic compounds. It primarily relies on fermentation and respiration processes to break down carbohydrates and amino acids, utilizing them for energy production. As a facultative anaerobe, it can switch between aerobic respiration in the presence of oxygen and fermentation in anaerobic conditions. This versatility allows it to thrive in various environments, including the host organisms it infects.
