[Cross reactions of higher type-specific capsular polysaccharides of Klebsiella in antipneumococcal sera].

Qualitative and quantitative precipitin reactions are given of the polysaccharides K60, K61, K65, K67-69, K70, K71, K73, and K83, also of depyruvylated K1. As expected, the last reacts more strongly in antipneumococcal (anti-Pn) VIII and X than does intact K1. K65 and K67 precipitate much of the same large fraction of anti-PnXXIII as does K47, showing that K65 and K67 also possess lateral non-reducing end-groups of L-rhamnose. The massive reaction of K83 in anti-PnII confirms the chemically demonstrated non-reducing end-groups of D-glucuronic acid in the repeating unit, Such groups, or 1,2-linked D-glcA, will probably also be found in K71.
