“…This is as predicted by TriversWillard hypothesis and may be associated with an increase in parasitic load especially the invasive A. sidemi (Hayward et al 2011). In recent years, the presence of A. sidemi was confirmed genetically in cattle (Moskwa et al 2015). This indicates the possible transmission of the parasite from wildlife to livestock.…”

We investigated the pattern of parasite egg shedding by European bison (Bison bonasus) in the Białowieża Primeval Forest. We found several groups of parasite eggs in bison faeces including Trichostrongylidae, Nematodirus spp., Aonchotheca sp., Trichuris sp. and Moniezia spp. Trichostrongylidae eggs were expelled from bison at the highest percentage (27.8 %) but in low numbers. The prevalence (percentage of faeces with parasite eggs) of other parasites did not exceed 12 %. The number of detected eggs of the parasite species differed: The highest was in Trichuris sp. and Moniezia spp. There were no significant differences in prevalence between male and female bison, with exception of Trichuris sp. whose eggs were more often detected in female faeces. The number of eggs per gram (EPG) of faeces was significantly higher in females for Aonchotheca sp. Parasite prevalence showed seasonal variation and was significantly higher for Trichostrongylidae, Nematodirus spp., Aonchotheca sp. and Moniezia spp. parasites in winter (December-March) compared to the snow-free period (April-November). We observed a 3-14 fold higher prevalence of these parasites in winter compared with the snow-free period. We assumed that factors such as season and bison sex have an influence on the level of excreted eggs. The determination of the factors affecting the rate of parasite egg excretion into the environment is important for the management of wild animals, especially endangered species such as the European bison.

“…There is relatively low number of cattle grazing in neighboring to the Forest pastures, however around 15% of bison, occasionally or seasonally and mainly from autumn until early spring, forage on pastures utilized also by cattle ( Kowalczyk et al., 2013 ). This indicates possibility of interspecies parasite transmission ( Moskwa et al., 2015 ).…”

“…A. sidemi was also found in deer in France ( Ferte et al., 2000 ). In recent years, the presence of A. sidemi was genetically confirmed in cattle, which indicates possible transmission from wildlife to livestock ( Moskwa et al., 2015 ). Previous studies from BPF have shown the influence of winter bison aggregation on A. sidemi and coccidia infection ( Radwan et al., 2010 , Pyziel et al., 2011 ) and on the seasonal pattern of parasite egg excretion ( Kołodziej-Sobocińska et al., 2016a ).…”

The full course of new parasite introductions in wild animals is difficult to accurately trace. We documented and analysed the invasive blood-sucking nematode Ashworthius sidemi (Trichostrongylidae) introduction and spread in European bison (Bison bonasus) from the initial phase of its progression. In the Polish part of the Białowieża Primeval Forest (BPF) the parasite was first found in 2000. From 2002 to 2015, 165 culled bison were investigated. The prevalence and intensity of A. sidemi Schulz, 1933 infection increased over the following years, reaching 100% of investigated bison four years after introduction and a maximal median intensity of 8200 nematodes per animal in the winter of 2008/2009. Afterwards, a significant decline of median infection intensity was observed to the minimum value of 410 nematodes per animal. Between 2011 and 2014 prevalence varied from 89 to 100%. Among the factors analysed, the number of years since introduction, herd size, age and sex proved to significantly influence infection intensity. A higher infection intensity was recorded in sub-adults compared to juveniles and adults. Males had significantly lower infection intensity than females, but this was the case for adults only. The highest infection intensities were recorded in the biggest bison herds, where the winter supplementary feeding of bison is intense. Moreover, the longer the parasite was present in the host population, the more important herd size became as a factor. Our study indicates that it is not solely biological factors that determine the spread of a newly detected parasite in wildlife, but that management practices can also have a strong influence. This is especially important in endangered species under intensive human care as the management practices may pose a threat to the species.

“…Since 2012, a drop of both infection intensity and prevalence has been observed in BPF while invasion is increasing in KF (Kołodziej-Sobocińska et al unpublished data). The first evidence for the presence of A. sidemi in cattle (PCR analysis) confirms the possible transmission of the parasite from wildlife to livestock (Moskwa et al 2015).…”

“…Our study provides direct evidence that a blood-sucking nematode invasion may cause deterioration of the blood parameters in wild animals and most likely affects their condition as a consequence. Taking into account the recent reports of the possible transmission of A. sidemi to cattle (Moskwa et al 2015) and the increasing use of farmland by bison (Hofman-Kamińska and Kowalczyk 2012; Kowalczyk et al 2013), continuous health monitoring and conservation management aimed at reducing parasite abundance in bison should be introduced to avoid serious consequences for this unique species and for cattle grazing on pastures used by bison.…”

Does the blood-sucking nematode Ashworthius sidemi (Trichostrongylidae) cause deterioration of blood parameters in European bison (Bison bonasus)?

European bison (Bison bonasus), after extinction in the wild at the beginning of twentieth century, were reintroduced in over 30 free-ranging populations in central and eastern Europe. Major threats to this species include disease and parasites. In the last decades, the highly pathogenic bloodsucking nematode Ashworthius sidemi (Trichostrongylidae) has been found in high infection intensity and prevalence within the abomasa of free-living European bison. We investigated the impact of this invasion on blood parameters associated with the red blood cell system in 64 bison (53 free-living and 11 captive) which were culled in two neighbouring populations in north-eastern Poland between 2008 and 2015. We observed a significant decrease in red blood cell count, haemoglobin and haematocrit relative to the intensity of A. sidemi infection. Furthermore, the same parameters were significantly lower, and the percentage of reticulocytes was increased in highly infected free-living bison compared to captive individuals. Studies indicate the urgent need to change the conservation management of herds because traditional management that includes supplementary feeding causes a large concentration of bison in winter feeding areas. This causes an increase in parasitic load which ultimately impacts on their condition. The reservoir of this parasite in wildlife may also adversely affect livestock grazing on pastures used by bison.
