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). Streptococcus pneumoniae There are 100 known serotypes of Streptococcus pneumoniae, the bacteria that cause pneumococcal disease. Streptococcus pneumoniae are lancet-shaped, gram-positive, facultative anaerobic bacteria with 100 known serotypes. Identification and Characterization of Streptococcus pneumoniae.

It is usually cultured on media that contain blood, but can also grow on a chocolate agar plate (CAP). On a blood agar plate (BAP), colonies of S. pneumoniae Alpha-hemolytic colonies of Streptococcus pneumoniae on sheep blood agar. Cultivation 24 hours in an aerobic atmosphere enriched with 5% CO 2, 37°C.

While OM does not have the high rates of mortality associated with invasive pneumococcal diseases, such as meningitis, it has an extremely high rate of morbidity, with most children suffering at least one episode of OM during their early childhood years. 2001-09-01 Zinc uptake by Streptococcus pneumoniae depends on both AdcA and AdcAII and is essential for normal bacterial morphology and virulence. Bayle L (1), Chimalapati S, Schoehn G, Brown J, Vernet T, Durmort C. In microbiology, colonial morphology refers to the visual appearance of bacterial or fungal colonies on an agar plate.Examining colonial morphology is the first step in the identification of an unknown microbe. The systematic assessment of the colonies' appearance, focusing on aspects like size, shape, colour, opacity, and consistency, provides clues to the identity of the organism, allowing Streptococcus pneumoniae can also develop antibiotic resistance by the timeless process of mutation and selection. The bacterium has a relatively fast growth rate and achieves large cell densities in an infectious setting, These conditions not only favor the occurrence natural transformation but also the emergence of spontaneous mutants resistant to the antibiotic.

Encapsulated, virulent strains isolated e.g., from sputum in patients with acute pneumonia, often forming highly mucoid, glistening colonies (production of capsular polysaccharide) surrounded by a zone of alpha-hemolysis. Morphology of Streptococcus pneumoniae They are gram positive bacteria. May lose gram +ve character in older cultures and appear gram –ve. They are non-sporing and non-motile bacteria. 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.
