First report of Eucoleus boehmi in red foxes (Vulpes vulpes) in Denmark, based on coprological examiantion

摘要

Red foxes can be infected with diverse range of parasite species that can be transmitted to humans and pet animals, and the differential diagnosis is essential for veterinary and zoonotic risk assessment. In the present study, faecal flotation and microscopy of parasite eggs was done on 31 foxes originating from two distant localities in Denmark, the city of Copenhagen in the north east part of the island Zealand and from the southern part of the peninsular Jutland. In total, eggs of Eucoleus boehmi were recovered from a surprisingly high number of foxes (n=22 samples; 71%). The findings represent the first observations of E. boehmi in Denmark, which is likely an overlooked infection of the upper respiratory tract of red foxes, which can be also found in other canids. Several morphological features of the eggs of E. boehmi can be used to distinguish it from other the closely related trichuroid eggs. Detecting cardiopulmonary parasites by faecal examination can be indicative of the presence of cardiopulmonary parasites based on the more sensitive post mortem analysis.
