Abstract

Many physicochemical factors affect the survival of Vibrio cholerae in the aquatic environment. An attempt was made to study the combined effect of pH and iron on the survival of V. cholerae in water in a laboratory environment. None of the 6 strains of V. cholerae used survived at pH 5.0; survival of all strains increased with increasing pH. The effect of ferric oxide on survival was significant for V. cholerae O1 only, not for non O1 strains. The longest survival of V. cholerae non O1 was 82 d, of El Tor V. cholerae 68 d, and of classical V. cholerae 56 d.

摘要

许多物理化学因素会影响霍乱弧菌在水生环境中的存活。本研究尝试在实验室环境下，探究pH值和铁对霍乱弧菌在水中存活的综合影响。所使用的6株霍乱弧菌在pH 5.0时均无法存活；所有菌株的存活率均随pH值升高而增加。仅三价铁对霍乱弧菌O1型的存活有显著影响，对非O1型菌株则无影响。非O1型霍乱弧菌的最长存活时间为82天，埃尔托型霍乱弧菌为68天，古典生物型霍乱弧菌为56天。
