Comparison between the control and the infected pups showed a significant increase of IL-17A levels at day 60 post infection (i.e. 64 days old), whereas Mbl2 was significantly upregulated at days 21 and 60 post infection (i.e. 25 and 64 days old respectively) (Fig. 3A,B). The gene discussed is MBL2; the disease is infection.
