Clostridium tetani is an obligate anaerobe that can cause tetanus. when it enters the human body, it can produce tetanus toxin. considering that c. tetani is an obligate anaerobe, which of the following explains how it can survive and cause disease in the human body? a. especially in deep wounds, c. tetani can sometimes survive in areas with damaged tissue and poor to no blood flow. b. c. tetani can only survive when other bacteria are available to consume oxygen and to keep oxygen levels low. c. it doesn't survive; it simply releases toxin as it dies. d. c. tetani can't access atmospheric oxygen, so it can grow as long as it stays on the surface of the skin rather than in well-oxygenated deeper tissues.
