Klebsiella Pneumoniae gram stain.

Klebsiella pneumoniae stain is a gram-negative, motile encapsulated found lactose fermentation, facultative anaerobic, rod-shaped bacteria of the normal flora of the oral cavity, skin and intestines. This is clinically important Klebsiella genus of Enterobacteriaceae;it is closely related to K. oxytoca from which it is the indole-negative, and its ability to both melezitose and 3-hydroxybutyrate are growing together. It occurs naturally in soil and about 30% of the strains can provide nitrogen in anaerobic conditions. Klebsiella Pneumoniae gram stain is the free-living Diazotroph, has its nitrogen-fixing system has been much studied.

Members of the Klebsiella stain typically express 2 types of antigens on the cell surface. First, lipopolysaccharide O-antigen, which are 9 varieties. The second is an antigen, capsular polysaccharide, with more than 80 varieties. Contribute to the pathogenicity and form the basis for the subtypes.
