Only very few studies have been published about the effect of enteric parasite infections [20] or enteropathogenic viruses [17] on fecal S100A12 concentrations in humans, and the role of S100A12 in parasite and viral infections is difficult to study using a traditional rodent animal model due to the lack of S100A12 in rodents [21]. Here, S100A12 is linked to viral infectious disease.
