SXTET lacks dfr18, orf3, orf4, and orf5. In El Tor O1 strain C10488, floR is preceded by a complete copy of orf6 and orfA (top). In contrast, in SXTMO10, there is a duplication of 640 bp (dark gray boxes) that flanks the genes dfr18, orf3, orf4, and orf5 (black). The locations of primers (TMP3 and TMP4) used for amplification of this area are also shown.
