These bacteria are extracellular and made up of non-motile and non-sporing cocci (round cells) that tend to link in chains. They are clinically important for humans, as they are an infrequent, but usually pathogenic, part of the skin microbiota that can cause Group A streptococcal infection.

Pneumococcal pneumonia is caused by the bacterium Streptococcus pneumoniae. This bacterium can cause contagious and potentially severe illness, including pneumonia, meningitis, and sepsis, so early diagnosis and treatment is important. Pneumococcal disease can affect many different systems in your body. It may result in conditions with mild symptoms like a sinus infection (sinusitis).
