8 sie 2023 · Streptococcus pneumoniae is a gram-positive, lancet-shaped bacterium and a cause of community-acquired pneumonia. Pneumococcal infections are present throughout the world and are most prevalent during the winter and early spring months.
Some general guidelines for conventional testing have been established; for example, the presence of gram-positive diplococci as the predominant morphotype on a Gram stain of “high-quality” sputum (>10 white blood cells per epithelial cell at a magnification of 400X) is considered good evidence of pneumococcal pneumonia . However, because ...
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 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.”
20 cze 2016 · If a pneumococcal infection is suspected or considered, Gram stain and culture of appropriate specimens should be obtained, when possible. Potential specimens may include 1 or more of the...
We reviewed the accuracy and yield of sputum Gram stains to diagnose bacterial pathogens in community-acquired pneumonia. Gram stains of good-quality specimens have high specificity for Streptococcus pneumoniae and Haemophilus influenzae, and can provide clinically actionable information for pathogen-directed therapies.
