SPATEs promote the survival of to the plasma complement system upon local hemorrhage and bacteremia.

spp. are the causative agents of shigellosis, which remains a leading cause of death in children under the age of 5. Symptoms of shigellosis include bloody diarrhea, associated to colon hemorrhage; in more severe cases bacteremia is induced.

Escherichia coli killing by epidemiologically successful sublineages of Shigella sonnei is mediated by colicins.

Background: Shigella sp. are enteric pathogens which causes >125 million cases of shigellosis annually. S.

The selective advantage of facultative anaerobes relies on their unique ability to cope with changing oxygen levels during infection.

Bacteria, including those that are pathogenic, have been generally classified according to their ability to survive and grow in the presence or absence of oxygen: aerobic and anaerobic bacteria, respectively. Strict aerobes require oxygen to grow (e.g.
