Literature Review Shigellae are rod-shaped gram-negative bacteria, that belong to the enterobacteria family. These bacteria possess pathogenicity within a human host, primarily targeting the GI tract of the human body. Shigellae obtain multiple properties that cooperate to its operation of survival. These bacteria are non-motile, facultative anaerobes, which allow Shigellae to utilize oxygen when oxygen is present to generate ATP, while also possessing the capability to make ATP when oxygen is not present, via fermentation (Anaerobic Respiration) . The genus…...
