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.

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.

Most S. pneumoniae serotypes can cause disease, but only a minority of serotypes produce the majority of pneumococcal infections. 2021-02-04 · Laboratory diagnosis, Treatment and Prevention of Streptococcus pneumoniae. Gram staining of sputum shows lancet shaped Gram-positive cocci in pairs. Sputum or blood is plated on blood agar and incubated at 37° C in the presence of 5–10% carbon dioxide. Most pneumococci are susceptible to penicillin.

Flow chart for identification and characterization of a S. pneumoniae isolate. 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.

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.

S.pneumoniae is also a major cause of meningitis, leading to high morbidity and mortality in pediatric and adult patients. The most frequently observed infection due to S.pneumoniae is otitis media. Other infections includes sinusitis, septic arthritis, osteomyelitis, endocarditis, peritonitis, cellulitis, brain abscesses. Diseases. Meningitis; Gram stain

Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus bovis, Streptococcus pneumoniae, etc. 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. Culture and identification during suspected Streptococcus pneumoniae infection. Flow chart for identification and characterization of a S. pneumoniae isolate.

The genus Streptococcus includes a heterogeneous group of different Gram positive species (>30) that are identified on Gram stain by their spherical or ovoid shape and their tendency to grow in pairs and chains. They are nonmotile, non-spore forming, and mostly facultatively anaerobic.

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.

by Gram-positive and Gram-negative bacteria. av S Nordin — två typer kallas för gram-positiva respektive gram-negativa bakterier. Skillnaden är att Streptococcus pneumoniae kan bli kompetent efter att den utsatts för vissa doser av vesicles in Gram-positive bacteria, mycobacteria and fungi.
