FIG 1.
Genetic summary of serotype 15B and serotype 15C variants. BLS141 and BLS142 were created by inserting rpsL (Smr) into the background of clinical isolate 0556-97 (serotype 15B) and 3031-06 (serotype 15C), respectively. The white region of wciZ arrowheads in BLS142 and BLS157 indicate the region of wciZ after the premature stop. The asterisks in BLS157 denote the wciZ region amplified from BLS142 which was transformed into BLS143 (as described in Materials and Methods). Gene fragments or prematurely truncated genes are denoted by arrows with jagged edges.
