Nevertheless, marked alterations have been reported in numerous laboratory findings, including cytokines (increase in interleukin 1β, IL-10), hematology (normocytic normochromic anemia and lymphopenia), and biochemical variables (hypoproteinemia, hypoalbuminemia, and hypoglycemia) in the Brucella-infected rather than the non-infected group [26]. Here, IL10 is linked to anemia.
