Life cycle: Species of Physaloptera are parasites of mammals and reptiles, which acquire the infections from ingesting insects containing infective larvae. Larvae ingested by possible paratenic hosts (such as anurans) generally attach to the gastric mucosa and can persist for varying periods of time ( Anderson 2000).
