How is Streptococcus pneumoniae classified?

How is Streptococcus pneumoniae classified?

Streptococcus pneumoniae resides asymptomatically in healthy carriers typically colonizing the respiratory tract, sinuses, and nasal cavity….

What is the difference between Streptococcus and pneumococcus?

Pneumococcal disease is caused by bacteria called Streptococcus pneumoniae (pneumococcus). People with pneumococcal disease can spread the bacteria to others when they cough or sneeze. Symptoms of pneumococcal infection depend on the part of the body affected.

What biosafety level is Streptococcus pneumoniae?

Biosafety Level 2
Biosafety Level 2 (BSL-2) practices are required for work involving isolates of S. pneumoniae, as this organism presents a potential hazard to laboratory personnel and the surrounding working environment.

Where is Streptococcus pneumoniae most likely found?

Streptococcus pneumoniae is a bacterium commonly found in the nose and throat. The bacterium can sometimes cause severe illness in children, the elderly and other people with weakened immune systems.

What is Streptococcus pneumoniae known for?

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.

Is Streptococcus pneumoniae harmful or helpful?

Streptococcus pneumoniae (pneumococcus) is a Gram-positive bacterium that is responsible for the majority of community-acquired pneumonia. It is a commensal organism in the human respiratory tract, meaning that it benefits from the human body, without harming it.

Is Streptococcus pneumoniae an obligate human pathogen?

Streptococcus pneumoniae as a complex relationship with its obligate human host. On the one hand, the pneumococci are highly adapted commensals, and their main reservoir on the mucosal surface of the upper airways of carriers enables transmission.

How does Streptococcus pneumoniae invade the body?

Access to the bloodstream by S. pneumoniae may occur through several pathways including via the lymphatics, via cell damage to the epithelial and endothelial cells, and via direct invasion of endothelial cells. Most likely all three pathways contribute to bloodstream invasion in an infected animal.
