Study looks at the energetic impact of brain-infecting parasites on California killifish

Parasites are well known for sucking energy from their hosts, but can they drain energy from hosts even before infection? A new study by Scripps Institution of Oceanography at the University of California San Diego and the Norwegian University of Life Sciences examined this question and found that a species of brain-infecting parasite can disrupt the metabolism of its host—the California killifish—both before and after infection.
