El Tor Vibrio cholerae and non-01 V. cholerae absorbed onto chitin particles could not only multiply in vitro, but also could partly survive with heating at 65-75 degrees C for 60-160 sec (7/40) or with 3.8-15 ppm of effective chlorine for 10 min (24/29). None of those unabsorbed onto chitin could survive at the above temperature, and only very few of those could survive with the above concentration of effective chlorine. These findings are conducive to the control of cholera transmission caused by the crustacean contaminated with chitin.
