[The antigenic structure of vibrions studied by means of agglutination and fluorescent antibodies].

Cross immunofluorescent and serological studies were made of strains of Vibrio coli of different forms-a short, commashaped strain and other long, spiral-shaped and serpent-like strains isolated from swine. Some standard strains of Vibrio foetus were also included for comparison. An antigenic difference was established between vibrions of long and short forms, as well as the known difference between strains isolated from swine and those from cattle which can be established by means of immunofluorescent techniques. Combined studies using immunofluorescence and serological methods give the possibility for rapid group and species typing of different strains of vibrions.
