Considering that prior work in salmonids often (Bjork et al., 2014; Holzer et al., 2021), but not always (Hurst et al., 2019), find significant upregulation of IL-10 following infection from myxozoans and that both myxozoans were detected at 100% prevalence at 14 and 21 dpd, it seems plausible these patterns are in part due to infection. Here, IL10 is linked to infection.
