Table 3 Comparison of cumulative quantitative reverse transcription polymerase chain reaction (qRT-PCR) and antibody responses (IgM, IgA, IgG) for 21 days following PRRSV inoculation 1

From: Kinetics of the porcine reproductive and respiratory syndrome virus (PRRSV) humoral immune response in swine serum and oral fluids collected from individual boars

  Serum (mean AUC and 95% confidence intervals) Oral fluid (mean AUC and 95% confidence intervals)

  1. 1 Individual boar PRRSV (loge geq/μl) and antibody (IgM, IgA, IgG) S/P responses over time were summarized as the area under the curve (AUC) prior to performing the statistical analysis.
  2. abc Superscripts within columns indicate statistically significant differences among means (Tukey’s Honestly Significant Differences test, p < 0.05).
