Site of infection: Intestine. Material deposited: CECOAL 0 0 112909 , 0 0 122104 , 0 1013101. References: González & Hamann (2007b) . Life cycle: The life cycle of this nematode is unknown. Apparently, freshwater turtles, their definitive hosts, may become infected by ingestion of copepods (intermediate hosts) or by feeding on paratenic hosts including aquatic snails, planktonophagus fishes and amphibians ( Moravec 1998 ).
