| evidence for serpulina hyodysenteriae being recombinant, with an epidemic population structure. | the population structure of serpulina hyodysenteriae was investigated using multilocus enzyme electrophoresis. a total of 231 isolates were divided into 50 electrophoretic types (ets), with a mean genetic diversity of 0.29 for the number of ets and 0.23 for the number of isolates. subsets of isolates from two australian states (71 isolates from victoria and 68 isolates from queensland) exhibited as much genetic variation as the entire collection. the calculated index of association (ia) for the ... | 1997 | 9353937 |
