1Respiration levels for CCH incubated for 25 h (CCH25) or 44 h (CCH44) were determined by comparing respiratory rates of CCH in each well of a plate to the corresponding A1 well that contained no supplements. (+ respiration was higher than in A1).
2Respiration levels for CCH exposed to M. synoviae WVU 1853 membrane fraction (1 mg/mL, 15 µL/well for 5 h before the measurement started) were determined by comparing respiratory rates measured during 24 h to those of CCH25.
3Respiration levels for CCH infected with live M. synoviae WVU 1853 (107 CFU/well for 14 h before the measurement started) were determined by comparing respiratory rates measured during 24 h to those of CCH44.
Legend:
+: Respiration above cut-off value set to 500 in at least one concentration of hormone/cytokine (area under corresponding graph: for CCH compared to A1, for CCH+MSm/CCH+MS compared to CCH).
−: Respiration lower than 500.
+/=; +/↑; +/↓: Respiration was detected and was, compared to respiration in CCH, equal, higher, or lower at different concentrations of hormones/cytokines.
