As either liver and/or small intestinal pathology usually drive host susceptibility to schistosomiasis morbidity,16,17 we further investigated for indications of liver or small intestinal pathology in these mice, as we reasoned that differential pathology in the absence of differential parasite burden might explain the susceptibility of Batf2−/− mice during acute schistosomiasis. Here, BATF2 is linked to schistosomiasis.
