加热或加氯处理下几丁质对ElTor弧菌的保护作用

Protection of Vibrio Cholcrae from Hcating and Chlorination by Chitin

吸附于几丁质微粒的ＥＩＴｏｒ弧菌与非０１群霍乱弧菌，不但具有繁殖能力，而且在加温６５～７５℃作用６０～１６０ｓ或在３８～１５ｍｇ／Ｌ有效氯作用１０ｍｉｎ下仍有部分残存；不含几丁质的对照组在相同温度中无一生存，在相同有效氯作用下极少残存。本研究为控制由甲壳类海产品传播霍乱的措施提供了参考数据。

I Tor Vibrio cholerae and non一01 V. cholerae absorbed onto chitin particles could not only mul-tiply in vitro, but also could partly survive with heating at 65一75℃ for 60一160 sec(7/40) or With 3.8一 15 ppm of effective chlorine for 10 min(24/29).None of those unabsorbed onto chitin could sur-vive 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.
