A Bacterium That is Pathogenic

Question

A bacterium that is pathogenic:
A) is flexible regarding use of metabolic pathways.
B) has genes similar to viruses.
C) is a disease-causing organism.
D) benefits from living inside humans and produces nutrients for us.

Accepted Answer

A pathogenic bacterium is a bacterium that is capable of causing disease in a host organism. Therefore, option C is the correct choice. Option A is incorrect because flexibility in metabolic pathways does not necessarily make a bacterium pathogenic. Option B is incorrect because not all pathogenic bacteria have genes similar to viruses. Option D is incorrect because pathogenic bacteria harm the host organism, rather than producing nutrients for it.
