Homework Answers
Answer: The bacterium that possesses a capsule always considered a pathogen because it is considered as a virulence factor. As capsule enhances the ability of bacteria to cause infection or disease by preventing the phagocytosis. The capsule acts as a guard which protects the cells from engulfment by macrophages.
