“…Amplification targeting DNA of the central part of the flagellin gene (230 bp; primers used: Bbs 1-1, 5¢-AACACACCAGCATCACTTTCAGG-3¢; Bbs 1-3c, 5¢-GAGAATTAACCCGCCTTGAGAAGG-3¢) characterized species of the B. burgdorferi sensu lato complex, 13 whereas a second PCR targeting a fragment of the chromosomal 66-kDa protein (171 bp; primers used: Bb-1, 5¢-AAAACGAAGATAC TCGATCTGTAATTGC-3¢; Bb-2, 5¢-TTGCAGAATTTGATAAAG TTGG-3¢) characterized B. burgdorferi sensu stricto. 14 . Amplification of a fragment of the chromosomal 66-kDa protein was carried out at annealing temperatures of 50°C and 48°C, respectively, using the same protocol.…”
