“…The identified parasites were in accordance with data collected by other authors from Switzerland and other countries [11,83–86]. This indicates that endoparasitosis is common in roe deer and not necessarily clinically significant, but it may contribute to the disease process when challenging environmental conditions or other weakening causes occur.…”

“…Furthermore, the fact that Chabertia ovina and small gastric worms have disappeared from the dataset are likely not only due to changes in the laboratory methods but also to a loss of knowledge over time. This hypothesis is supported by recent studies which have documented these parasites in roe deer from other countries [83,84,86]. Thus, targeted investigations are required to assess the current occurrence of gastric helminths and their importance in pathological processes in roe deer in Switzerland.…”

General wildlife health surveillance is a valuable source of information on the causes of mortality, disease susceptibility and pathology of the investigated hosts and it is considered to be an essential component of early warning systems. However, the representativeness of data from such surveillance programs is known to be limited by numerous biases. The roe deer (Capreolus capreolus capreolus) is the most abundant ungulate and a major game species all over Europe. Yet, internationally available literature on roe deer pathology is scarce. The aims of this study were (1) to provide an overview of the causes of mortality or morbidity observed in roe deer in Switzerland and to assess potential changes in the disease pattern over time; and (2) to evaluate the value and limitations of a long term dataset originating from general wildlife health surveillance. We compiled 1571 necropsy reports of free ranging roe deer examined at the Centre for Fish and Wildlife Health in Switzerland from 1958 to 2014. Descriptive data analysis was performed considering animal metadata, submitter, pathologist in charge, laboratory methods, morphological diagnoses and etiologies. Recurrent causes of mortality and disease pictures included pneumonia, diarrhea, meningoencephalitis, actinomycosis, blunt trauma, predation, neoplasms and anomalies. By contrast, other diagnoses such as fatal parasitic gastritis, suspected alimentary intoxication and reproductive disorders appeared only in earlier time periods. Diseases potentially relevant for other animals or humans such as caseous lymphadenitis (or pseudotuberculosis), salmonellosis, paratuberculosis and listeriosis were sporadically observed. The disease pattern in roe deer from Switzerland was largely in accordance with previous reports. The observed fluctuations were consistent with methodical and/or personnel changes and varying disease awareness. Nevertheless, despite such limitations, the compiled data provide a valuable baseline. To facilitate comparison among studies, we recommend systematically archiving all case documents and fixed tissues and to perform data analyses more regularly and in a harmonized way.

The persistent activity of ivermectin long-acting injection (IVM LAI; IVOMEC® GOLD, Merial; 3.15% ivermectin w/v) against nematode infections of cattle was evaluated under natural challenge conditions. Seventy nematode-free Brown Swiss calves were blocked by pre-treatment bodyweight and allocated randomly to seven groups of 10 animals each: saline (control) at 1 mL/50 kg bodyweight once on day 0 or IVM LAI at 1 mL/50 kg bodyweight (630 mcg IVM/kg) on either days 0, 7, 14, 21, 28, or 35. After housing until day 35, calves were grazed as one herd on a naturally contaminated pasture for 42 days. Calves were then weighed and housed for 4 weeks before being necropsied for parasite counting. Treatment with IVM LAI prevented the establishment (>90%, p < 0.05) of Dictyocaulus viviparus (100%), Bunostomum phlebotomum (100 %), Haemonchus contortus (98.6%), Ostertagia ostertagi/lyrata (94.9%), and Oesophagostomum radiatum (93.3%) for at least 77 days; Ostertagia leptospicularis (99.1%) for 63 days; Cooperia punctata (97.7%), Trichostrongylus axei (96.5%), and Ostertagia spp. inhibited larvae 4 (93.3%) for 56 days; Cooperia oncophora/surnabada (96.9%), Trichuris discolor (93.6%), and Cooperia spp. inhibited larvae 4 (98.8%); and Nematodirus spp. inhibited larvae 4 (97.1%) for 42 days. Calves of groups treated with IVM LAI had significantly (p < 0.001) higher days 0 to 77 weight gains than the saline-treated controls (28.40-39.25 vs 2.60 kg); the weight gains of the IVM LAI-treated groups, however, were not different from one another (p > 0.3). This study demonstrated a very high efficacy of IVOMEC® GOLD in preventing the establishment of a wide range of bovine nematodes for extended periods of time which was associated with a significant benefit to productivity in terms of weight gain.

“…Ebenfalls aus der gleichen Zeit stammt der Nachweis von Paramphistomum cervi bei 13 % des Rehwilds und 11 % des Rotwilds in Ostdeutschland [20]. In Nordrhein-Westfalen wurden dagegen Ende der 1990er Jahre Pansenegel weder bei Reh-, Dam-noch Rotwild nachgewiesen [52][53] [54]. Kurze Zeit später durchgeführte Untersuchungen an Muffelwild in Thüringen waren ebenfalls ohne Pansenegelbefund [22].…”

ZusammenfassungDie Paramphistomidose ist eine weltweit auftretende parasitäre Erkrankung bei diversen Wiederkäuern, ausgelöst durch verschiedene Pansenegelarten (u. a. Paramphistomum cervi, Calicophoron daubneyi und Paramphistomum leydeni). In Europa sind lokale Vorkommen von Pansenegelinfektionen bei Haus- und Wildwiederkäuern seit Jahrzehnten beschrieben. Mittlerweile gibt es Hinweise, dass die Paramphistomidose an Bedeutung gewinnt, denn in Großbritannien, Irland, Frankreich, Spanien, Belgien und den Niederlanden wurden teilweise hohe Prävalenzen festgestellt. Aktuelle Prävalenzdaten aus Deutschland liegen nicht vor. In neueren Untersuchungen in Norddeutschland, Hessen und Bayern konnte Calicophoron daubneyi, die auch in Europa aktuell am häufigsten vorkommende Pansenegelart, nachgewiesen werden. Die Entwicklung des Pansenegels ist an Zwischenwirte aus der Familie der Wasserlungenschnecken gebunden. Calicophoron daubneyi und der Große Leberegel Fasciola hepatica teilen im Laufe ihrer Entwicklung den gleichen Zwischenwirt, die Zwergschlammschnecke Galba truncatula. Der Endwirt nimmt die infektiösen Metazerkarien auf. Im Dünndarm schlüpfen die jungen Pansenegel und heften sich im Duodenum an. Danach wandern sie in den Pansen ein, wo sie als Adulte anfangen, Eier auszuscheiden. Die Infektion kann während der intestinalen Phase zu schwerem Durchfall und bei hoher Befallsintensität zum Tod führen. Die ruminale Paramphistomidose verläuft in den meisten Fällen subklinisch. Aktuell steht zur Diagnostik der koproskopische Einachweis mittels Sedimentationsverfahren zur Verfügung. Aufgrund der Ähnlichkeit besteht die Gefahr der Verwechslung mit Eiern des Großen Leberegels. Die Paramphistomidose kann mit Oxyclozanid behandelt werden. Über die Wirksamkeit anderer Wirkstoffe liegen widersprüchliche Ergebnisse vor. Umso wichtiger erscheint die Prophylaxe dieser Parasitose. Bekämpfungsvorschläge richten sich aufgrund der ähnlichen Epidemiologie nach den Empfehlungen, die zur Vorbeugung der Fasziolose abgegeben werden. Ob es sich bei der Paramphistomidose auch in Deutschland um eine sich ausbreitende Infektionskrankheit handelt, kann aktuell noch nicht beurteilt werden.
