title: Haemagglutinins and fimbriae of soft rot Erwinias.
abstract: Strains of phytopathogenic soft rot Erwinia spp. were examined for haemagglutinin (HA) production. Mannose-sensitive HA was found only in five of 15 strains of E. carotovora subsp. carotovora. Mannose-resistant HA (MRHA) was found in 12 of 15 strains of E.c. carotovora, ten of 13 strains of E.c. subsp. atroseptica and the single strain of E.c. subsp. betavasculorum, as well as all seven strains of E. chrysanthemi. MRHA, detectable only in a microtitre tray HA assay was of either broad- or narrow-spectrum activity when examined against blood of seven different animal species and could be inhibited by the beta-galactoside asialofetuin. Fimbriae of ca 10 nm diameter were found on MRHA(+) bacteria E.c. carotovora and E.c. atroseptica.
