Abstract
SUMMARY: Three strains of Vibrio were found to agglutinate both guinea-pig and human red cells. The vibrios differed in haemagglutination tests from fim-briated enterobacteria by showing only partial inhibition by mannose and by agglutinating guinea-pig and human red cells equally well. Electron microscopy of the vibrios revealed filamentous appendages which resembled the common fimbriae of Escherichia coli in having average diameters between 6 and 10 mμ and in being more numerous on organisms from liquid media than from solid media. The fimbriae on vibrios also had some characteristics of F fimbriae of enterobacteria. In comparative studies fimbriae which resembled common fimbriae of E. coli were found on Pseudomonas multi-vorans and Aeromonas liquefaciens.
