Abstract
Ribosomal DNA polymorphism was used to characterize strains of Escheri chia hermannii and to differentiate them from E. coli. DNA from 11 E. hermannii strains previously separated into three zymotypes by enzyme electrophoretic polymorphism was digested with HindIII and EcoRI restr iction enzymes and analysed by Southern blotting. The 10 ribotypes obt ained with EcoRI fell into 3 groups which correlated with the correspo nding zymotypes, and the 5 ribotypes obtained with HindIII were clearl y distinct from those of E. coli strains.
