Two epidemics of diarrhoeal disease possibly caused by Plesiomonas shigelloides

Abstract

Two epidemics of water-borne diarrhoeal disease involving a total of 1000 persons are reported. In both epidemics, none of the usual bacterial enteropathogens were recognized and Plesiomonas shigelloides was the only suspect aetiological agent isolated. The ecology of P. shigelloides was investigated in these outbreaks. It was recognized as an inhabitant of fresh surface water and its presence was closely related to warm weather. © 1978, Cambridge University Press. All rights reserved.
