Survey on intestinal helminth fauna of woodcocks (Scolopax rusticola) in Italy.

Abstract

Every year populations of the European woodcock (Scolopax rusticola) migrate from Central and Northern Europe to the Mediterranean basin. South of Italy is one of the most common wintering site for this species. Given that information on parasites of woodcocks is scarce, the present study aimed at identifying the parasitic species affecting woodcocks migrating in Italy. The gastrointestinal tract of 206 woodcocks hunted in Southern Italy was removed and examined for parasites. From each animal a faecal sample was analysed by flotation test. The necropsy showed the presence of cestodes, i.e. Paricterotaenia paradoxa (59.4%) and Aploparaksis filum (49.5%), and of acanthocephalan Prosthorhynchus scolopacidis (22.4%). In one bird we also detected Parastrigea robusta, which is a trematode until now reported only in mallards (Anas platyrhynchos). Mixed infections (i.e., polyspecific infections) were detected in 53 (27.6%) animals. The most common were those caused by A. filum and P. paradoxa (12.5%), and by P. paradoxa and P. scolopacidis (8.3%). Copromicroscopic examinations revealed the presence of eggs belonging to nematodes Syngamus spp. (1.94%) in 4 woodcocks and of eggs of cestodes Aploparaksis spp. (37.86%) in 78 woodcocks. The present results fill a gap in the knowledge on parasites affecting woodcocks.
