Hobbs BC, Rowe B, Kendall M, Turnbull PC, Ghosh AC. "Escherichia coli O
27 in adult diarrhoea," Journal of
Hygiene (Lond), 1976, 77:3 (Dec), 393-400
Escherichia coli O 27 H 7 was
found in 16 stool samples
submitted during a Caribbean cruise (Cruise Z) by 29 patients reporting
with diarrhoea. A retrospective search revealed E. coli O 27 H 7 in 11
of 20 and 2 of 14 stool cultures from patients on two previous cruises
(Y and X respectively) and in a culture from fresh cream (Cruise Y).
The repeated occurrence of E. coli O 27 H 7 in the absence of any other
apparent cause suggested that this serotype may have been responsible
for the diarrhoea. The results of pathogenicity tests suggested that
this strain elaborated heat-stable (ST) enterotoxin. The possibility
that food may have been the vector is discussed.
