First report of Eucoleus boehmi in red foxes (Vulpis vulpis) in Denmark, based on coprological examination

Abstract

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.

Parasite species of the endangered Iberian wolf (Canis lupus signatus) and a sympatric widespread carnivore

“…This could be attributed to the scarcity of Iberian wolves in the study area and its endangered status ( Torres and Fonseca, 2016 ). Likewise, the parasites found in the red fox had been previously described in Portugal ( Carvalho-Varela and Marcos, 1993 , Eira et al., 2006 , Guerra, 2012 , Silva et al., 2012 ) and in other European countries ( Mizgajska et al., 2000 , Saeed et al., 2006 , Magi et al., 2009 , Al-Sabi and Kapel, 2013 , Eleni et al., 2014 ). In Portugal, Eira et al., 2006 , Guerra, 2012 and Silva et al.…”

Gastrointestinal parasites of cats in Denmark assessed by necropsy and concentration McMaster technique

“…The samples were examined by a concentration McMaster technique (c-McMaster) with a sensitivity of 20 eggs per gram faeces (EPG), using a saturated NaCl and 50% glucose flotation solution (specific gravity 1.27) (Roepstorff and Nansen, 1998). Initially, different capillarid eggs were not distinguished, but a few faecal samples (n = 8) were also processed by an accredited, modified c-McMaster technique with sensitivity of 5 eggs per gram (Henriksen and Aagaard, 1975;Henriksen and Korsholm, 1984) and re-examined according to outer shell morphology (Bowman et al, 2002;Al-Sabi and Kapel, 2013). In short, 4 g faeces were suspended in 36 ml distilled water.…”

First morphological and molecular analysis of Eucoleus boehmi like eggs in dogs from Argentina

“…1). According to the observed features and the available morphological and morphometric identification keys, eggs from dogs were assigned to the Eucoleus genus (Magi et al 2012;Al-Sabi and Kapel 2013;Alho et al 2016).…”

“…Eucoleus boehmi (Supperer 1953) has been reported in dogs from Italy, Portugal, and USA and in red foxes from Italy, Denmark, and Austria (De Liberato et al 2009;Magi et al 2012;Al-Sabi and Kapel 2013;Clark et al 2013;Veronesi et al 2014;Alho et al 2016;Hodžić et al 2016;Cervone et al 2017). This parasite is found in the nasal turbinates, frontal and paranasal sinuses of canids.…”
