Pneumococcal [noo-muh-KOK-uhl] disease is a name for any infection caused by bacteria called Streptococcus pneumoniae, or pneumococcus.
ICD-10 code J13 for Pneumonia due to Streptococcus pneumoniae is a medical classification as listed by WHO under the range - Diseases of the respiratory system .
Streptococcus pneumoniae are lancet-shaped, gram-positive, facultative anaerobic bacteria with more than 100 known serotypes. Most S. pneumoniae serotypes can cause disease, but only a minority of serotypes produce the majority of pneumococcal infections.
Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic (under aerobic conditions) or beta-hemolytic (under anaerobic conditions), aerotolerant anaerobic member of the genus Streptococcus. They are usually found in pairs (diplococci) and do not form spores and are non motile.
Lobar pneumonia, unspecified organism.
Pneumococcal pneumonia is the most common type of bacterial pneumonia. The risk for pneumococcal pneumonia increases with age and certain chronic conditions.
Definitively diagnosing Streptococcus pneumoniae infection generally relies on isolating the organism from blood or other normally sterile body sites. Tests are also available to detect capsular polysaccharide antigen in body fluids.
Group B strep (streptococcus) is a common bacterium often carried in the intestines or lower genital tract. The bacterium is usually harmless in healthy adults. In newborns, however, it can cause a serious illness known as group B strep disease.Sep 21, 2021
In the medical setting, the most important groups are the alpha-hemolytic streptococci S. pneumoniae and Streptococcus viridans group, and the beta-hemolytic streptococci of Lancefield groups A and B (also known as “group A strep” and “group B strep”).
Historically, Streptococcus pneumoniae and other streptococci of the viridians group are classified as alpha-hemolytic bacteria on the basis of a greenish halo that surrounds colonies when grown aerobically on blood agar plates (1, 2).Dec 9, 2020

The formal name of the bacterium is now Streptococcus pneumoniae. (The "strepto-" means twisted and "-coccus" comes from the Greek kokkos meaning berry.) Because of its coming in pairs, it has also been called Diplodocus pneumoniae. "Pneumoniae" refers to its propensity to settle in the lungs and cause pneumonia.Mar 29, 2021
