Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic (under aerobic conditions) or beta-hemolytic (under anaerobic conditions), facultative anaerobic member of the genus Streptococcus. They are usually found in pairs (diplococci) and do not form spores and are non motile. Streptococcus pneumoniae are Gram-positive bacteria in the shape of a slightly pointed cocci. They are usually found in pairs (diplococci), but are also found singly and in short chains. S. pneumoniae are alpha hemolytic (a term describing how the cultured bacteria break down red blood cells for the purpose of classification).

They are 0.5 x 1.25 µm in diameter. They are mostly found in pairs (diplococci). Also In throat swabs Streptococcus pneumoniae can occur in its avirulent form (oropharyngeal carriage of pneumococci is common and they are considered to be part of normal flora). The colonies are only 0.5-2 mm in diameter, surrounded by zone of alpha-hemolysis and due to autolysis, often develop a dimpled rather a craterlike appearance.

Streptococcus pneumoniae in Gram Staining. Main diseases caused by Streptococcus pneumoniae: Bacterial pneumonia: Most common bacterial cause, especially in infants and elderly.
Streptococcus pneumoniae, a gram-positive, alpha-hemolytic bacterium, causes pneumococcal infections of the upper respi-ratory tract leading to pneumonia, as well as infections such as acute sinusitis, otitis media, conjunctivitis, meningitis, osteo-myelitis, septic arthritis, endocarditis, peritonitis, pericarditis, cellulitis, and brain abscess. Streptococcus pneumoniae (the pneumococcus) is the classic example of a highly invasive, Gram-positive, extracellular bacterial pathogen. It is a major cause of morbidity and mortality globally causing more deaths than any other infectious disease. Streptococcus pneumoniae are lancet-shaped, gram-positive, facultative anaerobic bacteria with 100 known serotypes. Most S. pneumoniae serotypes can cause disease, but only a minority of serotypes produce the majority of pneumococcal infections. Pneumococci are common inhabitants of the respiratory tract.

Streptococcus pneumoniae in Gram Staining. Main diseases caused by Streptococcus pneumoniae: Bacterial pneumonia: Most common bacterial cause, especially in infants and elderly. 2010-05-01 · Streptococcus pneumoniae (the pneumococcus) colonizes the human nasopharynx and can also cause diseases, including otitis media, pneumonia, bacteraemia, and meningitis. The organism produces a range of colonization and virulence factors, including the polysaccharide capsule, surface proteins and enzymes, and the toxin pneumolysin (PLY).
