Color-enhanced Transmission Electron Micrograph (TEM) of negatively stained Klebsiella pneumonaie, a Gram-negative, non-motile, encapsulated, lactose fermenting, facultative anaerobic, rod shaped bacterium found in the normal flora of the mouth, skin, and intestines. K. pneumoniae can cause the disease Klebsiella pneumonia, and ranks second to E. coli for urinary tract infections in older persons. Magnification: 20,000x at 35mm. (Apparently the cell lost its capsule and pili in this old culture.)
