Comparative study of Vibrio cholerae non-O1 protease and soluble hemagglutinin with those of Vibrio cholerae O1.
Protease and soluble hemagglutinating activities produced by a non-O1 Vibrio cholerae strain isolated from a patient with diarrhea were compared with similar activities produced by V. cholerae O1. The soluble protease activities were indistinguishable in heat stability, immunodiffusion, inhibition by antiserum, and electrophoretic analysis. On the other hand, the soluble hemagglutinating activities of both strains were not completely identical. The hemagglutinating activity of the non-O1 V. cholerae strain was not inhibited by Zincov; it was more sensitive to inhibition by normal serum, and it had an unusual pattern of heat stability. Heating at 100 degrees C resulted in some recovery of activity of a sample previously inactivated by heating at 60 degrees C.
