| Abstract: | The adhesin F18ac purified on Sepharose CL 4B column chromatography and SDS-PAGE stained with Coomassie Blue and Western blotting using specific anti-F18ac serum presented one band of approximately 17kDa. Gold immunolabeling revealed that the adhesin F18ac has a fimbrial structure on the bacterial surface. The first 27 amino acid residues of the N-terminal portion of the adhesin F18ac, showed 92.5% homology (25 amino acids) with the F107 (F18ab) fimbriae. |
