S. pneumoniae is a fastidious bacterium, growing best at 35-37°C with ~5% CO 2 (or in a candle-jar). 2013-07-29 Streptococcus pneumoniae. Streptococcus pneumoniae in clinical material occurs in two distinctive forms. 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.

Microscopy and Staining Perform Gram staining of the sample (sputum/CSF) Gram staining shows Gram positive lanceolate shaped diplococci; 2. Culture and Sensitivity 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.

Staphylococcus, Gram stain Streptococcus pneumoniae Streptococcus pneumoniae, Gram stain Neisseria spp., Gram stain … 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. Se hela listan på textbookofbacteriology.net For Gram staining, the following material will be required: Sample - A sputum sample of patients with pneumonia may be used Compound microscope Reagents (Gram stain reagents) Glass slide A burner Water Oil immersion Gram-stain: Gram-positive cocci : Microscopic appearance: Lanceolate (ovoid) cocci in short chains, diplococci and single cocci : Clinical significance: Despite the name, the organism causes many types of pneumococcal infections other than pneumonia. Acute sinusitis; Otitis media; Meningitis; Bacteremia; Sepsis; Osteomyelitis; Septic arthritis; Endocarditis; Peritonitis Streptococcus pneumoniae. Pneumococcus is a gram-positive, catalase-negative, facultative anaerobic bacterium that typically produces α-hemolysis (partial hemolysis) on blood agar plates (Figure 2-4). Gram stain classically reveals lancet-shaped diplococci.
