Researchers tracked parasite-induced disease and death in reintroduced wolf packs in Yellowstone National Park, finding that mange did not infect wolves until 2007. The diseases that infected the wolves quickly were all viral, including canine distemper and parvovirus, while mange is a skin infection caused by scabies mites.
Researchers found Hematodinium sp. and its sister species are a major problem for crab fisheries, causing 'bitter crab' disease. The parasites have bacteria-like endosymbionts that increase their chances of survival outside the shrimp, leading to significant damage to infected crustaceans.
The expanding raccoon population in Europe threatens native species and human health with infectious diseases such as rabies and Baylisascaris procyonis. The spread of these illnesses is linked to the raccoon's adaptability, high reproductive potential, and lack of natural predators.
