Characterization of type 1 and mannose-resistant fimbriae of Erwinia spp.
Type 1 fimbriae from Erwinia carotovora subsp. carotovora and mannose-resistant fimbriae from Erwinia rhapontici were purified and characterized. The type 1 fimbrillin had an apparent molecular weight of 16,500; that of the mannose-resistant fimbrillin was 18,000. The amino-terminal amino acid sequences of the two fimbrillins were related, but tryptic peptide maps showed significant differences between the proteins. No serological cross-reaction was found between the two fimbrial filaments, nor did they cross-react with type 1 or type 3 fimbriae purified from other enterobacterial species. Immunofluorescent staining of bacterial populations revealed that they were heterogeneous with respect to fimbriation.
