- Medical parasitology traditionally has included the study of three major groups of animals: parasitic protozoa, parasitic helminths (worms), and those arthropods that directly cause disease or act as vectors of various pathogens. A parasite is a pathogen that simultaneously injures and derives sustenance from its host.

Ask a parasite ecologist how they got into parasites, and they’ll likely tell you it was by accident. Wood grew up on New York’s Long Island and dreamed of becoming a marine biologist. She imagined a career spent swimming with dolphins. In college, however, there were no opportunities for undergraduate marine biology research. The closest thing she...
Katie Leslie is sorting through ribbons of intestines belonging to a rockfish that’s been dead for 41 years. So far Leslie, a research technologist in Wood’s lab, has found only the remnants of the animal’s last meal. Rockfish are notoriously wormy, but this specimen is proving to be exceptionally parasite-free, until “Oh, wait, yes!” Leslie calls ...
Parasite increases still get most of the attention—which is why Wood is attuned to parasite decreases and their implications for humans and wildlife. Some are to be celebrated, such as the effort to eradicate the Guinea worm, a spaghettilike parasite that grows up to 2.5 feet long inside an infected person’s digestive system before migrating to and...
Apr 14, 2023 · Overview. What are parasites? Parasites are organisms that live in, on or with another organism (host). They feed, grow or multiply in a way that harms their host. However, they need their host for their survival. For this reason, they rarely kill their host, but they often carry diseases that can be life-threatening. Advertisement.

Sep 22, 2022 · Animals. Some ecologists value parasites — and now want a plan to save them. Parasites can be important to ecosystems, but climate change is imperiling some of them. The human head louse shown here is an ectoparasite, which means it lives on the outside of its host. Gilles San Martin/Flickr ( CC BY-SA 2.0) By Stephen Ornes.
