Prosthogonimus macrorchis, are poultry flukes found within the oviduct. Birds are infected with P. macrorchis after consuming an infected dragonfly. Because of the use of aquatic invertebrates as intermediate hosts, this parasite is commonly found in fowl surrounding water features, especially the Great Lake area. Potential clinical signs are weight loss, malformed eggs, or decreased egg production. Adult flukes are small, approximately 8mm long, often found within the oviduct on necropsy. A recent case report also described P. macrorchis in the egg of a backyard chicken. At this time, there is no labeled dewormer for P. macrorchis in poultry.
