Klebsiella Pneumoniae


Klebsiella Pneumoniae is a gram-negative, nonmotile, lactose-fermenting, encapsulated, facultative anaerobic, rod-shaped bacterium. This bacteria is present in the mouth, skin and intestines as normal flora in animals and humans, but it can cause damage to lungs if inhaled. More specifically, it affects the alveoli in lungs that causes bloody sputum. The Klebsiella species have lately become an important pathogen in nosocomial (hospital-acquired) infections. Generally, infections caused by Klebsiella are observed in people with a weakened immune system. Outside the hospital, the most common condition caused by this bacteria is pneumonia, mostly bronchitis and bronchopneumonia.
