In the present report, the results of a comparative study in the detection of all Echoviruses reference strains as well as of 38 clinical isolates are presented. Using RT-PCR with already published primer pairs (UG(52)-UC(53), 292-222, 012-011 and EUG2a, 2b, 2c-EUC2) from the 5'UTR, the VP1 region as well as a long genomic fragment including the VP1 3' end, the entire coding sequence of 2A, 2B, and the 5' moiety of the 2C-coding region amplification was effective with all reference and clinical Echovirus isolates with primer pair UG(52)-UC(53) while with 292-222 and 012-011 were amplified 27/28 reference Echovirus strains and all clinical isolates. As far as EUG2a,2b,2c-EUC2 is concerned, the RT-PCR gave a positive result for 26/28 reference Echovirus strains and 34/38 clinical isolates. The sequence analysis of a large part of the 5'UTR has revealed that there is no correlation between 5'UTR identity and the currently recognized human enterovirus species. It has been suggested that part of VP1 coding sequence would correlate well with serotype since a number of important neutralization epitopes, as well as receptor recognition sequences, lie within the VP1 coding sequence. Therefore, UG(52)-UC(53) and 292-222 primer pairs seem to be the most appropriate for Echovirus detection and, moreover, UG(52)-UC(53) is useful for the classification of enteroviruses into genetic clusters (sub-groups) while 292-222 for the identification of enteroviruses by amplicon sequencing.
