Morphology 1. Encapsulated, spherical, ovoid, lancet-shaped cocci 2. Size: 0.5-1.25 μm 3. Laboratory diagnosis of Streptococcus pneumoniae infection is based on finding characteristics shape of the organism in the sputum, characteristic colony morphology, biochemical reactions, susceptibility to certain diagnostic discs and latex agglutination test.

Ex: TSA supplemented with 5% sheep’s blood In this study, we report the isolation of colony morphology variants from Streptococcus pneumoniae serotype 3 biofilms. The colony variants differed in colony size (large, medium, and small) and their mucoid appearance on blood agar. The small nonmucoid variant (SCV) emerged during the initial attac … 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.

Pneumokocker (Streptococcus pneumoniae) är en art av bakterier inom släktet streptokocker som kan orsaka ett stort antal olika sjukdomar.. Pneumokocken är en kapslad grampositiv bakterie under kategorin streptokocker som finns i näsans normalflora hos ungefär hälften av alla barn och även i normalfloran i munhålan och i de övre luftvägarna hos friska personer, men kan komma att bli What is the morphology of Streptococcus pneumoniae? Streptococcus pneumoniae cells are Gram -positive, lancet-shaped cocci (elongated cocci with a slightly pointed outer curvature).

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.

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.

May have pili for adherence. 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.
