NC - negative control, YP - Y. enterocolitica-positive sera, BP - B. abortus-positive sera.
^aThe percent similarity was calculated as the number of proteins common to the compared antisera immunoreactions divided by the total number of proteins in these antisera immunoreactions × 100.
^bPositive reaction detected in immunoblotting.
^cNegative reaction detected in immunoblotting.
