Question

My Q.was `Kind of bacteria` therefore given ans .is not correct?

Answer 1

That's because your question was rather broad and unclear.  Many kinds of bacteria can cause an infection in humans.  That is why infections are cultured, so you can grow and identify the bacteria causing the infection.  The term infection merely refers to the process of the human immune system in response to a foreign body within it- and the cause may be bacterial or viral.  There is no one specific "kind of bacteria", there are several thousand kinds which will stimulate an immune response from the body.  That response is commonly called an infection.  If you want a more specific answer, ask a more specific question.
