FIG. 2.
Mutational profiles of the VP1-coding region of the isolates from the patient and the contacts. The ratio of signals obtained from hybridization of MARSH with reference sample (Sabin 2) and analyzed strains: Sabin 2, black; isolate PV2/3d, red; contact isolate C1, blue (the other samples C2, C3, and C4 had similar profiles [data not shown]); sewage sample, green. x axis, the nucleotide coordinates on poliovirus genome; y axis, the ratio of fluorescent signals between reference and test samples. The arrow shows the location of mutation U2909→C.
