Studies on the growth of Escherichia coli O157:H7 strains at 45.5 degrees C.

Abstract excerpt

The objectives of the present report were to examine the ability of 18 strains of Escherichia coli O157:H7 to grow in EC broth at 42.4, 43.5, 44.5, and 45.5 degrees C, and to document the incidence of phenotypic variants present in low numbers that are capable of growth at 45.5 degrees C in EC broth. Among the 18 strains of E. coli O157:H7 studied, only 3 were capable of producing turbid growth with gas formation...
