Efficacy Study 2: Detection of FMDV nucleic acid in air filters collected from animal rooms. FMDV nucleic acid in air samples that were collected on air filters from each of the three animal rooms, were detected by rRT-PCR, and a Ct value < 40 was scored positive. Air filters were collected daily for the first 18 days and then on alternate days to 43 days. The experimental design is diagramed in Fig. 1b
