[Klebsiellae isolated from patients and healthy subjects. III. Biochemical types of klebsiellae].

By the difference in fermentation of glucose, lactose, saccharose, inosite, adonite, behaviour in IMViC tests, relation to urine and hydrogen sulfide formation there were revealed 10 biochemical types among 120 strains of klebsiellae. Klebsiellae of biotypes 1 and 2 were the most frequently isolated from the patients; biotypes 3--10 were less frequent. Klebsiella of biotypes 1 and 2 were revealed in healthy persons; biotypes 3--10 were never found. Biochemical reactions on whose basis klebsiellae were referred to the definite biochemical type proved to be stable.
