Fig. 2: Measurement of clinical parameters on acquisition feeding calves challenged with B. bovis S74-T3Bo Texas strain.

A Rectal temperature in oC is shown on the Y-axis and the days post challenge on the X-axis. B Packed cell volume (PCV) is shown on the Y-axis, and the days post-challenge are presented on the X-axis. C Quantification of the average number plus standard deviation of copies of B. bovis msa-1 gene by qPCR on gDNA extracted from the blood of infected calves at days 0−, 3−, 7−, and 9-day post-infection. The error bars represent the standard deviations of samples at each time point.
