What type of infection is Pneumococcal Pneumonia?
Lower Respiratory Infection
Causative agent of Pneumococcal Pneumonia?
-Always present in samples as diplo, that's what pneumococci means
-Can also be caused by other agents
S & S of Pneumococcal Pneumonia?
1. 1-2 days of runny nose, congestion, rise in temp
2. Cough, fever, chest pain, sputum production
3. Sputum becomes rust colored from blood
4. Severe chest pain, shallow, rapid breathing
How is Pneumococcal Pneumonia spread?
-Encapsulated pneumococci inhaled into alveoli, and rapidly multiply causing inflammatory response
-Up to 30% of healthy people carry encapsulated pneumococci in throat
How do the pneumococci evade phagocytosis?
They have a general polysaccharide capsule that blocks phagocytosis
Virulence factor that damages ciliated epithelium in lungs
How does Pneumococcal Pneumonia cause difficulty breathing?
Accumulations of bacteria in alveoli causes difficulty breathing, along with sputum accumulation
What further damage can pneumococci do?
*May enter bloodstream leading to:
-Sepsis of blood
-Endocarditis (heart valve infection)
For those healthy individuals that carry capsulated pneumococci in their throat, how does it keep from getting in their lungs?
-The mucociliary escalator effectively keeps the bacteria from reaching the lungs
-Risk of infection increases when this defense is impaired
Upper respiratory infections
Lower respiratory infections
