as forward primers and P7 as reverse primer) was performed on the
P1/P7 amplicons after purification with a QIAquick PCR Purification
Kit (Qiagen). The sequences were assembled using Sequencher
4.1 software. They were then compared with selected
nucleotide sequences in the GenBank database using BLAST (version
BLASTN 2.2.18; National Center for Biotechnology Information
