Streptococcus pneumoniae , or pneumococcus, is an encapsulated, gram-positive, catalase-negative, alpha-hemolytic, facultative anaerobic member of the genus Streptococcus that is sensitive to ethylhydrocupreine hydrochloride. It produces an immunoglobulin A (IgA) protease and is the most common cause of meningitis, otitis media in children, sinusitis, and community-acquired pneumonia with "rusty" sputum.

This video covers key aspects of S pneumoniae infection, including the symptoms, diagnosis, treatment, and pathology.
