The present study was conducted to examine the intestines of three freshwater fish species of Planiliza abu, Aspius vorax, and Silurus triostegus, collected from Thi-Qar Governorate, Iraq, for Neoechinorhynchus iraqensis parasitic infection. The large subunit 28S ribosomal DNA was used to identify this spiny-headed worm species. The results of the current study recorded ten isolates of N. iraqensis in Iraq. All the isolates were recorded in the International Gen Bank.
