Spheroidal bacterium (Streptococcus pneumoniae) that causes human diseases including pneumonia, sinusitis, ear infection, and meningitis. Usually occurring in the upper respiratory tract, this gram-positive (see gram stain) coccus is often found in a chain configuration and surrounded by a polysaccharide capsule.
