Abstract
Thirty single-nucleotide polymorphisms were used to track the spread of the seventh pandemic caused by Vibrio cholerae. Isolates from the 1991 epidemic in Latin America shared a profile with 1970s isolates from Africa, suggesting a possible origin in Africa. Data also showed that the observed genotypes spread easily and widely.
摘要
三十个单核苷酸多态性被用来追踪由霍乱弧菌引起的第七次大流行的传播。1991 年拉丁美洲的疫情分离株与 20 世纪 70 年代非洲的分离株具有相同的特征，表明可能起源于非洲。数据还表明，观察到的基因型易于广泛传播。
