Figure 1. Clinical course of RSV infection in adult BALB/c mice. BALB/c mice were infected with RSV-RFP and were followed up to 21 days post-infection (dpi). (A) Weight loss and (B) clinical score peaked at 5 dpi, with significant weight gain observed at 21 dpi. (C) Lung RSV viral titre was measured using qPCR. RSV viral titre was raised at 3 dpi, peaked at 5 dpi and returned to baseline by 21 dpi. Data are displayed as mean ± SEM; n= 6 per group (A and B) or n=3-6 (C). Statistical analysis was done by Kruskal-Wallis test with Dunn’s multiple comparison compared to baseline (day post infection 0), *p<0.05.
