Ie. Martin et al., EVALUATION OF RIBOTYPING AS EPIDEMIOLOGIC TOOL FOR TYPING ESCHERICHIA-COLI SEROGROUP O157 ISOLATES, Journal of clinical microbiology, 34(3), 1996, pp. 720-723
A total of 121 representative Escherichia coli 0157:H7 and 0157:NM (no
nmotile) isolates were characterized by ribotype, phage type, verotoxi
n genotype, and genomic fingerprints generated by pulsed-field gel ele
ctrophoresis. Ribotyping was not able to discriminate between 0157:H7
isolates, and phage typing and pulsed-field gel electrophoresis were t
he most valuable and discriminatory techniques.
