Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic member of the genus Streptococcus. [1] S. pneumoniae cells are usually found in pairs and do not form spores and are non motile. [2] As a significant human pathogenic bacterium S. pneumoniae was recognized as a major cause of pneumonia in the late ...
Pneumococcal infection is an infection caused by the bacterium Streptococcus pneumoniae. [1]S. pneumoniae is a common member of the bacterial flora colonizing the nose and throat of 5–10% of healthy adults and 20–40% of healthy children. [2]
Pneumococcal pneumonia is a type of bacterial pneumonia that is caused by Streptococcus pneumoniae (pneumococcus). [1] It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia , and one of the common types of pneumococcal infection .
Streptococcus pneumoniae is the most common bacterial cause of pneumonia in all age groups except newborn infants. Streptococcus pneumoniae is a Gram-positive bacterium that often lives in the throat of people who do not have pneumonia. Other important Gram-positive causes of pneumonia are Staphylococcus aureus and Bacillus anthracis.
S. agalactiae, or group B streptococcus, GBS, causes pneumonia and meningitis in newborns and the elderly, with occasional systemic bacteremia. Importantly, Streptococcus agalactiae is the most common cause of meningitis in infants from one month to three months old.
The bacterium Streptococcus pneumoniae, a common cause of pneumonia, imaged by an electron microscope. Pneumonia is due to infections caused primarily by bacteria or viruses and less commonly by fungi and parasites. Although more than 100 strains of infectious agents have been identified, only a few are responsible for the majority of cases.
Despite the emergence of antibiotics as a treatment for group A streptococcus, cases of iGAS are an increasing problem, particularly on the continent of Africa. [5] There are many other species of Streptococcus, including group B streptococcus Streptococcus agalactiae, and Streptococcus pneumoniae, which cause
Another cause of neonatal CAP is Chlamydia trachomatis, which, though acquired at birth, does not cause pneumonia until two to four weeks later. It usually presents with no fever and a characteristic, staccato cough. CAP in older infants reflects increased exposure to microorganisms, with common bacterial causes including Streptococcus ...
