Beyond Parasitism
The liver can be an indicator of the health of an individual or of a group, which can be especially important to identify agents that can cause disease in multiple species. To better characterize hepatic lesions in stranded harbor porpoises ( Phocoena phocoena), we analyzed the livers from 39 porpoi...
