We report the restriction fragment length polymorphism (RFLP) patterns of a 440-bp-long 5' non-coding region (5' NCR) amplification target of all 34 reference Coxsackie B and ECHO (enteric cytopathic human orphan) enterovirus strains and a total of 42 serotypically pre-assigned clinical isolates, in order to afford meaningful comparisons among these patterns and those of polioviruses. The RFLP patterns of reference Coxsackie B strains differed from one another and from those of polio and ECHO reference enteroviruses except from Coxsackie B1 and B2, which, although they differed from one another, had identical RFLP patterns with ECHO 17 and 13, respectively. The 28 ECHO reference strains formed a more variable viral group including strains with RFLP patterns distinct from one another and from those of polio and Coxsackie B enteroviruses, and others with RFLP pattern identities common to other ECHO viruses and Coxsackie B1 and B2 but not polioviruses. The RFLP patterns of the clinical isolates and their corresponding serotypically assigned reference Coxsackie B and ECHO strains presented the most notable variations. The observed differences between serotype and genotype-dependent assignments within the 440-bp long 5' NCR target sequence of Coxsackie B and ECHO enteroviruses were in sharp contrast to the analogous situation with polioviruses. These findings support the specificity of the described method for clinical diagnostic genotyping of polioviruses and demonstrate that the 440-bp-long target sequence follows a different evolutionary process in polio and non-polio enteroviruses that is particularly prominent between reference non-polio strains and their serotypically assigned clinical isolates.
