    <p>Bone marrow derived macrophages (BMM) or dendritic cells (BMDC) from young adult (6–8 weeks, dark bars) and aged (18–24 months, light bars) were stimulated <i>in vitro</i> with CpG, Fluzone (FZ) or both (FZ+CpG) overnight. Up regulation of MHC class II relative to unstimulated cells (media) was measured using flow cytometry on (A) BMM (F4/80+/CD11b+) and (C) BMDC (CD11c+/CD11b<sup>med</sup> /F4/80-). TNF-α production was measured by ELISA in supernatants from (B) BMM and (D) BMDC. Readings were taken as an average of triplicate wells. Results shown are mean values + S.D and are representative of 2 independent experiments.</p

    <p>Young adult mice (6–8 weeks) vaccinated twice, 2 weeks apart, with Fluzone (FZ x2), Fluzone+CpG (FZ+CpG) and unvaccinated controls were challenged with 1x10<sup>4</sup> p.f.u of A/California/09 H1N1. Five mice per group were sacrificed at day 7 post-infection. (A) The frequency of neutrophils (CD3-/Ly6C+) and (B) CD3+/CD8+ T-cells was measured by flow cytometry in homogenates of the right lobe of the lung. Dots represent individual mice and horizontal lines represent average +/-SEM where *p<0.05. (C) Lung virus titers from pooled mice (n = 5 per group) were determined day 7 post challenge using homogenates from the left lobe of the lung. Equal volumes of lung homogenate were pooled from 5 mice in each group and the horizontal bar represents average of duplicate wells. Data shown is representative of 2 independent experiments.</p

    <p>Young adult (6–8 weeks) and aged (18–24 months) C57/BL6 mice (n = 5–8 mice per group) were vaccinated with Fluzone (FZ), Fluzone+CpG (FZ+CpG) or left unvaccinated as controls. Approximately 4 weeks later, all groups were challenged with 1x10<sup>4</sup> p.f.u of A/California/09 H1N1 virus. Weight loss (A) and (C) and survival (B) and (D) were monitored daily in young adult and aged mice respectively. Individual data points represent average weight loss within the group of surviving mice +/-SEM.</p

    Results of PEDV N-gene RT-qPCR tests on environmental samples from coupons and rectal swabs from pigs used for bioassay. Results from all diagnostic tests conducted for the study are reported for each replicate, one row for each replicate. Test results, Ct value and genomic copies are reported for PCR tests on pre and post treatment environmental samples from coupons. Test result and Ct values are reported for PCR tests on rectal swabs from pigs 3 and 7 days post inoculation for the bioassay. (XLSX 12 kb
