This study found Plorocerci dasyatidis, a trypanorhynch cestode, in Gasterosteus aculeatus from a lake in Bulgaria. The prevalence of this parasite in the fish was 3.73% with an intensity range of 1-7 and mean intensity of 2.40 +/- 1.17. This is the first record of P. dasyatidis in G. aculeatus and in Bulgaria.
Plerocerci of the trypanorhynch cestode Progrillotia dasyatidis Beveridge, Neifar & Euzet, 2004 (Progrillotiidae) were isolated from the gallbladder of the three-spined stickleback Gasterosteus aculeatus from a small freshwater marsh in the Lake Atanasovsko Wetlands, a coastal area adjacent to the Black Sea coast, Bulgaria. The parasite was recorded in five out of 134 fish individuals studied (prevalence 3.73%, intensity 1-7, mean intensity 2.40 +/- 1.17 and mean abundance 0.09 +/- 0.06). A description of the plerocerci is presented, expanding data on intraspecific variation. The present report is the first record of P. dasyatidis from G. aculeatus (new host record) and from Bulgaria (new geographical record). Recording only plerocerci with evaginated scoleces in the sticklebacks is consistent with the hypothesis that teleosts are paratenic hosts and not intermediate hosts of P. dasyatidis.
