Relationship between Habs serotypes and 2-amino sugar composition of Pseudomonas aeruginosa

Thirteen Habs-serotype strains could be classified into 11 groups depending on the characteristic patterns of 2-amino sugar composition; strains of serotypes 2, 5, and 7 had the same pattern, and each other serotype strain had its own distinctive pattern. In our classification, fucosamine and quinovosamine were of importance. We found that fucosamine from strain P14 (Habs serotype 1) was of the D configuration only, unlike DL-fucosamine from strain N10 (Habs serotype 11).
