From the article:
The researchers found that bacteria such as pneumococci release large quantities of hydrogen peroxide, and that this causes inactivation of inflammasomes thereby weakening the immune system […] Our studies demonstrate that hydrogen peroxide is an inhibitor of an important component of the inflammatory machinery suggesting that the mechanism we have uncovered is a common strategy employed by many microbes to thrive within us,“ says Saskia Erttmann, first author in the study and former member of Nelson Gekara’s research group.
Role for vitamin C:
“One of the best known substances with the ability to neutralize hydrogen peroxide and that could hence boost anti-bacterial immunity are vitamins such as Vitamin C found in fruits. Perhaps the old adage ‘an apple a day keeps the doctor away’ is not off the mark,” adds Nelson Gekara.
