Question

Some bacterial pathogens only cause disease when injected into tissue and are not able to grow or cause disease on skin or other surface-exposed regions. One example is Clostridium tetani (tetanus). Which type of metabolism would you expect these pathogens to use?

Answer 1

Anaerobic chemoorganotrophy.

Step-by-step explanation:

Anaerobic chemoorganotrophs may be defined as the organisms that has the ability to prepare their food with the help of organic chemicals in the basence of oxygen. The microorganism uses this metabolism to cause disease in other organism.

The pathogens like Clostridium tetani use the anaerobic chemoorganotrophs bacteria as they injected into the tissue and do metabolism without the presence of oxygen. They can not cause disease on skin surface as abundant oxygen is present on the body surface.

Thus, the answer is anaerobic chemoorganotrophy.
