Researchers hope that shipworms and their microbes might reveal new sorts of antimicrobial substances or provide other industrial applications. Keep the grass cut short in areas where dogs or cats regularly defecate. But they do possess shells - tiny ones on their anterior ends, which they use with devastating effectiveness to bore deeply into their favorite food source, wood. The infection that results from this infestation is called onchocerciasis. They may concentrate bacteria, viruses, harmful chemicals and other pollutants in their bodies and can cause sickness and spread disease when eaten by humans.

Whipworms are an intestinal parasite that affects dogs and humans. That led researchers to a veritable Kuphus polythalamia paradise: the stinky lagoon of a long-abandoned log farm. To identify new anti-apicomplexan drugs, we investigated the compounds produced by symbiotic bacteria of shipworms, marine mollusks that burrow into and eat wood .
