title: A new mannose-resistant haemagglutinin in Klebsiella.
abstract: Strains of Klebsiella of the species (or 'patho-bio-sero-geogroups') Kl. atlantae, Kl. edwardsii and Kl. rhinoscleromatis produced neither haemagglutinins (HAs) nor fimbriae; strains of Kl. ozaenae were HA- but some produced type-6 fimbriae; and strains of Kl. pneumoniae (sensu stricto) and Kl. aerogenes that produced the mannose-sensitive HA (MS-HA) formed type-1 fimbriae. Most strains of Kl. aerogenes produced, in addition, one or both of the mannose-resistant HAs, MR/K-HA or MR/P-HA. The former, associated with type-3 fimbriae, was produced by 95%, and the latter by 57%, of the Kl. aerogenes strains. Some of the properties of the MR/P-HA, apparently a non-fimbrial HA not previously recognised in Klebsiella, are described.
