Clonal relationship among atypical enteropathogenic Escherichia coli strains isolated from different animal species and humans.

abstract：:A total of 85 isolates of mesophilic, aerobic, heterotrophic bacteria were isolated from the gut, peristomial membrane, and coelomic fluid from specimens of the sea urchin Echinus esculentus from the Clyde Sea area of Scotland. These isolates were compared with 26 isolates from sand and seawater in the same locality. ...
