摘要: The mycotoxin deoxynivalenol (DON) has been shown to regularly occur at relevant concentrations in feed designed for aquaculture use, but little is known about the consequences of its presence on organisms that consume DON-contaminated feed. Previous studies indicated a down-regulation pro-inflammatory responses carp (Cyprinus carpio L.) after 4 weeks feeding DON. present study examined time course innate immune orally administered Changes mRNA levels genes different organs (head kidney, trunk spleen, liver, and intestine) were observed indicating immune-modulating properties immune-modulatory effects during acute phase DON exposure characterized by activation both pro- anti-inflammatory cytokines enzymes carp. subchronic arginases culminating increased arginase activity head kidney leukocytes 26 days treatment. These results suggest profound this fish aquaculture.
