How do anaerobic bacteria make it to their final destination?

    How do anerobic bacteria make it to their final destination????

    For example, Plaque must be built up around the gum line to allow anerobic bacteria to colonize. But, the environment before they get their consist of Oxygen. So how do they get there in the first place.

    You got many kind of aerobic/anaerobic system.

    Strict aerobe: require oxygen and have only an oxygen respiratory chain.

    Facultative anaerobe: can grow aerobically and anaerobically. These bacteria tend to produce acid when they are anaeorbically. Have an respiratory chain and other non-oxygen dependent energy producing mechanism

    Microphiles: can grow in aerobic and anaeroic envriomenent but prefer low oxygen environment. Have an respiratory chain and other non-oxygen dependent energy producing mechanism. Some of their mechanism are sensitive to oxygen.

    Strict Anaerobes: sensitive to oxygen during growth and have non-oxygen dependent energy producing mechanism.

    Oxygen resistant anaerobes: identical to anaerobes but have mechansim to protect them against oxygen. They do not use oxygen. Most of the time they are refered to as facultative anaerobes.

    Some of the bacteria producing plaque are oxygen resistant anaerobes therefore they do not require an oxygen-free environment. Facultative anaerobes also can cause plaque. They grow first aerobically then switch to anaerobic growth. Some strict anaerobes will produce spores making then resistant to oxygen. Oxygen does not kill them unless they start to utilize energy and grow.

    Thanks, I was under the understanding that they were non spore producing strict anerobes.
