[Features of metabolism of Klebsiella genus bacteria].
Some metabolic peculiarities of bacteria of the genus Klebsiella were investigated. The bacteria under study were isolated from different sources and varied in virulence. The pathogenic and saprotrophic enterobacteria were discriminated based on their response to the addition of carbohydrates or nitrate to the medium. Pathogenic Klebsiella spp. exhibited mainly the mixed formic-acid type of fermentation and were more resistant to nitrates than saprotrophic bacteria with the butanediol type of fermentation. The bacteria Klebsiella pneumoniae subsp. pneumoniae isolated from different sources, such as patients, healthy persons, or the environment, exhibited no substantial differences in metabolism and virulence. It was inferred that these bacteria themselves cannot cause disease, and their isolation in morbid states is an indirect result of dysbacteriosis.
