FIG. 2.
Southern blot with chromosomal DNA from HPI-positive Salmonella strains 1649 (lane 1) (group IIIa), group IIIb strains 50/90 (lane 2), 461/95 (lane 3), 658/95 (lane 4), 845/96 (lane 5), 1376/95 (lane 6), 1380 (lane 7), SARC8 (lane 8), 1474 (lane 9), 1757 (lane 10), SARC7 (lane 11), and 1494 (lane 12), and group VI strains 1443 (lane 13) and SARC13 (lane 14). Strain SARC14 (lane 15) was the negative control, and Y. pestis strain KIM6+ (lane 16) served as the positive control. Chromosomal DNA was digested with BssHII and probed with the amplification product of PCR 30 (see table at http://www.uni-wuerzburg.de/infektionsbiologie/PCR-HPI.htm), representing part of the fyuA sequence.
