Anaerobic bacteria in wounds

Postby SysBio » Sun Mar 22, 2009 4:57 am

I read somewhere that anaerobic bacteria are commonly found to infect wounds.

Can someone explain why that is? I didn't think that blood was a super anaerobic environment...ie. dont the red blood cells carry oxygen?

My best guess: Inside recent wounds you don't get much blood flow as capillaries are cut, therefore low concentrations of oxygen.
It also depends on the type of anaerobe- Faculative, obligate or aerotolerant. Not all anaerobic bacteria are obligates(will die when exposed to oxygen). They can be faculative(can use oxygen if present) or aerotolerant(name says it, dont use oxygen at all but can survive in it).
A wise man once said to me:
"Build a man a fire, and he'll be warm for a day. Set a man on fire, and he'll be warm for the rest of his life."

Only the fittest chickens cross the road.

Obligate anaerobes are able to infect deep wounds, tissues and organs which are poorly oxygenated.

makes sense....basically: wounds become poorly oxygenated environments

thanks for the replies
