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. The estimated number of Americans with pneumococcal ...
It was discovered that the pneumococcus's capsule made it resistant to phagocytosis, and in the 1920s it was shown that an antibody specific for capsular polysaccharide aided the killing of S. pneumoniae. In 1936, a pneumococcal capsular polysaccharide vaccine was used to abort an epidemic of pneumococcal pneumonia.
Resistant pneumococcal strains are called penicillin-resistant pneumococci (PRP), [51] penicillin-resistant Streptococcus pneumoniae (PRSP), [52] Streptococcus pneumoniae penicillin resistant (SPPR) [53] or drug-resistant Strepotococcus pneumoniae (DRSP). In 2015, in the US, there were an estimated 30,000 cases, and in 30% of them the strains ...
Atypical bacteria causing pneumonia are Coxiella burnetii, Chlamydophila pneumoniae (), Mycoplasma pneumoniae (), and Legionella pneumophila.. The term "atypical" does not relate to how commonly these organisms cause pneumonia, how well it responds to common antibiotics or how typical the symptoms are; it refers instead to the fact that these organisms have atypical or absent cell wall ...
The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
The propensity of S. pneumoniae to become competent is critical to the bacterium's development of antibiotic resistance. [2] A substantial fraction of cells in the culture of species whose appearance of competence has been studied shows that specific growth conditions (ex. growth-limiting conditions) have led to the development of competence.
Pneumococcal disease spreads through direct contact with respiratory secretions such as saliva or mucus. Children younger than five-years old and adults 65 years and above are at an increased risk ...
[13] [15] Pneumonia is also the leading cause of death in children less than five years of age in low income countries. [15] The most common cause of pneumonia is pneumococcal bacteria, Streptococcus pneumoniae accounts for 2/3 of bacteremic pneumonias. [16] Invasive pneumococcal pneumonia has a mortality rate of around 20%. [14]
