maintenance 'host' of Shigella represent the external environment and is its
persistence due to, as yet unidentified, traits also present in the 'free-living'
E. coli strain? Are some of the same traits perhaps shared by the other diarrheal
pathotypes of E. coli ?
Although there is an increasingly sophisticated understanding of the molec-
ular and physiological means by which E. coli diarrheal pathogens cause dis-
ease, there are many significant gaps in our understanding of the ecology/
epidemiology of these diseases.
