Meningitis caused by H. influenzae and meningococci has a better prognosis than cases caused by group B streptococci, coliforms and S. pneumoniae. [2] In adults, too, meningococcal meningitis has a lower mortality (3–7%) than pneumococcal disease.
Streptococcus pneumoniae is the cause of Osler's triad of meningitis, pneumonia, and endocarditis. The portal of entry for this triad is said to be the lungs, followed by meningitis and endocarditis. Significant risk factors are heavy alcohol consumption, old age, splenectomy, immunosuppression, etc. Endocarditis typically involves the aortic ...
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.
While a few different bacterial infections can lead to meningitis, S. pneumoniae is one of the leading causes of this infection. Pneumococcal meningitis occurs when the bacteria goes from the blood to the central nervous system, which is made up of the brain and the spinal cord. Here, the infection will spread and cause inflammation, leading to ...
While many infectious agents can infect the adrenals, an acute, selective infection is usually meningococcus. [3] Pseudomonas aeruginosa can also cause WFS. [4] WFS can also be caused by Streptococcus pneumoniae infections, a common bacterial pathogen typically associated with meningitis in the adult and elderly population. [2]
Some of the possible symptoms of chronic meningitis (due to any cause) include headache, nausea and vomiting, fever, and visual impairment. Nuchal rigidity (or neck stiffness with discomfort in trying to move the neck), a classic symptom in acute meningitis, was seen in only 45% of cases of chronic meningitis with the sign being even more rare in non-infectious causes.
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 ...
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]
