During the present cholera pandemic the El Tor biotype of Vibrio cholerae has completely displaced the classic biotype, except in Bangladesh. We studied the distribution of these two biotypes in twenty-four rural districts during epidemics in 1988-89; there was clustering of the classic biotype in the southern region and of the El Tor biotype in all other regions. These findings suggest that the southern coastal region is now (and may always have been) the habitat of classic cholera. The selective distribution of V cholerae O1 biotypes in Bangladesh may have been affected by ecological changes occurring in the country.
在当前的霍乱大流行期间，霍乱弧菌的埃尔托生物型已完全取代了经典生物型，但在孟加拉国除外。我们研究了这两种生物型在1988 - 1989年疫情期间24个农村地区的分布情况；经典生物型集中在南部地区，而埃尔托生物型则分布在所有其他地区。这些发现表明，南部沿海地区现在（而且可能一直以来）都是经典霍乱的栖息地。孟加拉国霍乱弧菌O1生物型的选择性分布可能受到该国生态变化的影响。
