Mean viral loads, symptom scores, and respiration rates for calves in study 2. Viral loads were quantified from nasal swabs by qRT-PCR, and bRSV RNA values were normalized to GADPH cellular mRNA. Cumulative symptom scores and respiration rates were calculated based upon daily physical exams of each animal. The mean values for placebo-treated calves (n = 3) and GS1-treated calves on day 1 of treatment (n = 4) (white circles) or day 3 of treatment (n = 6) (gray circles) are plotted as a function of time postinfection (p.i.), and the positive error bars represent the standard errors of the means.
