This image is a light micrograph of Gram-stained S. pneumoniae (also known as S. pneumococcus ), rounded bacteria (cocci) that usually occur in pairs and sometimes short chains. Their blue color indicates they are Gram-positive. Magnification is 1450X when printed 10-cm wide.
Jan 31, 2024 · Streptococcus pneumoniae in Gram Staining Bacterial pneumonia: Most common bacterial cause, especially in infants and the elderly. Pneumococci in alveoli stimulate the release of fluid, red and white cells producing “rusty sputum.”
Streptococcus pneumoniae (pneumococci) are gram-positive, alpha-hemolytic, aerobic, encapsulated diplococci. Pneumococcal infection is a major cause of otitis media, pneumonia, sepsis, meningitis, and death. Diagnosis is by Gram stain and culture.
Streptococcus pneumoniae (also known as pneumococcus) is a Gram-positive, extracellular, opportunistic pathogen that colonizes the mucosal surfaces of the human upper respiratory tract (URT). Up to 27–65% of children and <10% of adults are carriers of S. pneumoniae and carriage involves a commensal relationship between the bacterium and the ...

Aug 14, 2023 · Introduction. The Gram staining is one of the most crucial staining techniques in microbiology. It gets its name from the Danish bacteriologist Hans Christian Gram, who first introduced it in 1882, mainly to identify organisms causing pneumonia. [1] .
Oct 4, 2022 · Essential features. Lancet shaped encapsulated gram positive diplococci. Alpha hemolytic, optochin (P disk) susceptible, bile soluble. Negative: catalase, oxidase and indole. Normal nasopharyngeal flora. Major cause of pneumonia, bacteremia, meningitis, sinusitis, otitis media. 2 million infections per year; 6,000 deaths.
