1Isolates with one fragment; 2Isolates with two fragments. The data represent the number of responders/number of tested individuals (the percentage of responders is given in parentheses). a: P = 0.005, CJ-2002 OR-II > CJ-1993 OR-II; b: P = 0.04, CJ-2002 > PA OR-II; c: P = 0.01, CJ- 2002 > CJ-1993; d: P = 0.02, CJ- 2002 > PA. The Chi-square test was used to analyse the difference in prevalence of positive responses.
