What does Streptococcus pneumoniae do?
Streptococcus pneumoniae is the most common cause of middle ear infections, sepsis (blood infection) in children and pneumonia in immunocompromised individuals and the elderly. It can also cause meningitis (inflammation of the coverings of the brain and spinal cord) or sinus infections.
How do you abbreviate Streptococcus pneumoniae?
FA stain (digitally colored). Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic (under aerobic conditions) or beta-hemolytic (under anaerobic conditions), aerotolerant anaerobic member of the genus Streptococcus.
What is Streptococcus pneumoniae name?
Pneumococcal [noo-muh-KOK-uhl] disease is a name for any infection caused by bacteria called Streptococcus pneumoniae, or pneumococcus. Pneumococcal infections can range from ear and sinus infections to pneumonia and bloodstream infections.
How can you identify Streptococcus pneumoniae?
S. pneumoniae can be identified using Gram stain, catalase, and optochin tests simultaneously, with bile solubility as a confirmatory test. If these tests indicate that the isolate is S. pneumoniae, serological tests to identify the serotype can be performed.
Is Streptococcus pneumoniae rod shaped?
Abstract. Streptococcus pneumoniae is an oval-shaped Gram-positive coccus that lives in intimate association with its human host, both as a commensal and pathogen. The seriousness of pneumococcal infections and the spread of multi-drug resistant strains call for new lines of intervention.
How did Streptococcus pneumoniae get its name?
The formal name of the bacterium is now Streptococcus pneumoniae. (The “strepto-” means twisted and “-coccus” comes from the Greek kokkos meaning berry.) Because of its coming in pairs, it has also been called Diplodocus pneumoniae. “Pneumoniae” refers to its propensity to settle in the lungs and cause pneumonia.
What shape is Streptococcus pneumoniae?
Streptococcus pneumoniae are lancet-shaped, gram-positive, facultative anaerobic bacteria with more than 100 known serotypes. Most S. pneumoniae serotypes can cause disease, but only a minority of serotypes produce the majority of pneumococcal infections.
What does Streptococcus pneumoniae look like under a microscope?
Streptococcus pneumoniae bacteria are gram-positive cocci arranged in chains and pairs (diplococci) on microscopic examination. A green, α-hemolytic, zone surrounds S. pneumoniae colonies on blood-agar plates.
What is Streptococcus pneumoniae?
Streptococcus pneumoniae. Streptococcus pneumoniae (S. pneumoniae) are lancet-shaped, gram-positive, facultative anaerobic bacteria with over 90 known serotypes. Most S. pneumoniae serotypes can cause disease, but only a minority of serotypes produce the majority of pneumococcal infections. Pneumococci are common inhabitants…
Where can I find media related to Streptococcus pneumoniae?
Wikimedia Commons has media related to Streptococcus pneumoniae. Centers for Disease Control and Prevention (2012). “Ch. 16: Pneumococcal Disease”. In Atkinson W; Wolfe S; Hamborsky J (eds.).
How many known serotypes of Streptococcus pneumoniae are there?
There are 100 known serotypes of Streptococcus pneumoniae, the bacteria that cause pneumococcal disease. Streptococcus pneumoniae are lancet-shaped, gram-positive, facultative anaerobic bacteria with 100 known serotypes.
Why was Streptococcus pneumoniae renamed in 1974?
It was renamed Streptococcus pneumoniae in 1974 because it was very similar to streptococci. Streptococcus pneumoniae played a central role in demonstrating that genetic material consists of DNA.
