Streptococcus pneumoniae is an oval diplococcus that is optochin sensitive, should prepare a Gram-stain of his/her Staphylococcus and Streptococcus

Streptococcus pneumoniae (SP) is one of three bacterial pathogens most frequently isolated by culture from middle ear effusions of children with both acute and chronic otitis media (others are Haemophilus influenzae and Moraxella catarrhalis) (Forbes et al., 2008). 2020-02-02 Usefulness of immunohistochemical diagnosis of streptococcus pneumoniae in formalin-fixed, paraffin-embedded specimens compared with culture and gram stain techniques. Guarner J(1), Packard MM, Nolte KB, Paddock CD, Shieh WJ, Tondella ML, McGee L, Zaki SR. those organisms that stained blue/violet with Gram’s stain are gram-positive bacteria and include Streptococcus pneumoniae (found in the lungs of those with pneumonia) and Streptococcus pyogenes (from patients with Scarlet fever) while those that were decolorized are gram-negativebacteria such as the Salmonella Typhi that is associated with Micrograph of Gram-stained Streptococcus pneumoniae bacteria in sputum.

2: Division: Staphylococci divide in various directions (multiple axes). Division occurs in one linear direction (single axis). 3: Catalase Test: Positive (Catalase is an enzyme to converts hydrogen peroxide to water and oxygen gas). Negative: 4: Enriched Media Streptococcus pneumoniae.

Immunologic detection of pneumococcal capsular material (“bacterial antigen”) generally does not add information beyond what is determined by Gram stain, although nuclear probes may eventually be useful in this situation. Other infections. As noted above, S. pneumoniae can be implicated in a wide variety of infectious states.

11: Species Differentiation – Coagulase test – Novobiocin sensitivity test – Biochemical tests – Type of hemolysis – Cell wall carbohydrate group (A, B, C, etc) – Bile Solubility Test – CAMPT Test – Optochin Sensitivity Test 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 and do not form spores and are non motile.

Pneumococci are common inhabitants of the respiratory tract. S. pneumoniae can be identified using Gram stain, catalase, and optochin tests simultaneously, with bile solubility as a confirmatory test. If these tests indicate that the isolate is S. pneumoniae, serological tests to identify the serotype can be performed.

2013-01-22 Streptococcus pneumoniae. Overview: Streptococcus pneumoniae is a Gram-positive, non-spore-forming, non-motile, lancet-shaped coccus anaerobe and a member of the Streptococcaceae family of bacteria (Figure 1).This organism has a capsule comprised of peptidoglycan and teichoic acid that protecting it from complement C3b opsonization, and is alpha-hemolytic.
