Supplemental Fig. S2 shows the response of sera from
M. hyorhinis challenged animals and antigens from the
other three mycoplasmas. The only potential crossreactivity
was late in the infection with the M. flocculare
antigen. Fig. S3 shows cross-reactivity with the sera from
M. hyosynoviae challenged animals. Although no positive
reactions were observed, late in the infection, two animals
approached a positive response with the M. flocculare
antigen. Fig. S4 shows cross-reactivity with sera from M.
flocculare challenged animals. Cross-reactive responses are
shown with the M. hyorhinis antigen. Borderline responses
were measured in one animal by day 22, a second by day 46
