BRSV-Snk challenge in calves with low or moderate passive immunity: effect on airway resistance and reactance. Experimental challenge by inhalation of aerosolized BRSV passaged in gnotobiotic calves (BRSV-Snk) was performed in five calves with moderate levels of BRSV-specific maternal antibodies (MDA). Lung function was measured using the forced oscillation technique, and a tightly fitting face mask; before challenge on post-infection day (PID) 0, and after challenge, on PID 6. Resistance (Panel A) and reactance (Panel B) at 10Hz were calculated and presented as kPa/L/s.
