Infectious Diseases and Microbiology - Opportunistic Pneumonia ( Klebsiella pneumoniae) 
Opportunistic Pneumonia due to Klebsiella pneumoniae
Large mucoid capsule, Gram-negative rod of Klebsiella pneumoniae.
K pneumoniae can be found in the large intestine, water, and soil. Although it is rare, colonization of the oropharynx can happen to people whose host defenses are weakened, such as chronically ill patients, alcoholics, and the elderly. Pneumonia results from germs aspirated from the oropharynx.

Opportunistic necrotizing pneumonia and urinary tract infections.

Pathophysiology 
Numerous virulence factors are present in K pneumoniae, such as a thick mucoid capsule, a variety of proteases, and cell wall endotoxin.

Sensitivity testing is necessary since K pneumoniae is resistant to a variety of antibiotics.
