Streptococcus pneumoniae bacteria is found in two types: a type III-S (smooth) and type II-R (rough) strain. The smooth strain covers itself with a polysaccharide capsule that protects it from the host's immune system, resulting in the death of the host, while the II-R strain doesn't have that protective capsule and is defeated by the host's immune system.

The smooth type has a "coat" that prevents it from attacks from the host's immune system and it is very virulent.
