Alaria americana

Species of fluke

Alaria americana is a species of trematode in the family Diplostomidae. All Diplostomidae species infect carnivorous mammals by living in their small intestines as mature worms. A. americana is most frequently found in temperate regions, predominantly in northern North America. Its habit is extremely diverse, as the species occupies four different hosts throughout its lifetime. It thrives in areas close to water as water is needed for several developmental stages to occur. It has been isolated to a wide range of North American mammals as definitive hosts, including cattle, lynx, martens, skunks, bobcats, foxes, coyotes, and wolves.
