^*The number of clones corresponding to each dominant, co-infecting or recobminant genotype is indicated after the slash, wherever this number is not identical to the total number of clones sequenced. Parent sequences contributing to recombination are separated by a dash and are listed in the order in which they are recombined. The number after the slash indicates the number of recombinants found (totals 29).
