Données préliminaires sur les parasites de la marmotte alpine (Marmota marmota) dans les Pyrénées du sud-ouest. Preliminary data on Alpine marmot (Marmota marmota) parasites in South-Western Pyrenees.

Résumé

The translocation of wild animals has an impact on the sanitary state of wild and domestic animals that share their habitat with the translocated animals. The sanitary study of Alpine marmot in the Pyrenees is particulary important because it is an introduced species, that has recently colonized this mountain range and could have introduced several parasitarian, virical, bacterial and fungical diseases which could also be new species for this area. Alpine marmots could also be affected by pyrenean diseases coming from other pyrenean vertebrates that share the same environment. The preliminary coprological anlisis of 62 drops and 12 necropsies indicates the presence of: Coccidia (Eimeria sp. similiar to type 2, described by Bassano et al. 1992), Trematoda (non identified Digenea), Cestoda (Ctenotaenia marmotae) Nematoda (Ascaris sp., Capillaria hepatica, Trichuris sp. and Tricoestrongilidae). The number of taxa is low compared to the results of Alpine studies even if a loss of some parasites can occur in traslocated populations. Other non specific species found in the Alps are missing. Parasites which are new for Alpine marmots appear: Capillaria hepatica and an unidentified Trematoda.
