Seven rainbow trout sera tested failed to agglutinate any of the strains tested. All agglutinating activity was lost upon boiling the antigen, therefore, the fish antibodies are due to surface antigens (K-antigens) and not to somatic antigens. The specific V. parahaemolyticus strain No. 3525 belongs to the serological type 03:K30, which might be common to the sea waters of the Eastern United States.

S. flexneri 6 contains both aerogenic and anaerogenic strains which are identical serologically. It is not surprising that S. flexneri 6 is not separable from other S. flexneri types on the basis of DNA relatedness (overall genetic makeup) (4). The Manchester biotype is seen in the United States, and is easily separable from other Enterobacteriaceae by biochemical tests. One can no longer assume à priori that any given biochemical reaction rules an organism out of Shigella.
