Helminths of Talpa europaea [Insectivora, Talpidae] in Southwestern Europe

100%

tom 50

nr 2

The helminth fauna of the European mole (Talpa europaea L., 1758) was studied on the basis of 269 host individuals from 39 localities in France and Spain. Twelve helminth species were recorded: two digeneans - Ityogonimus lorum (Dujardin, 1845) (Brachylaimidae) and Nephrotrema truncation (Leuckart, 1842) (Troglotrematidae); one cestode – Multitesticulata filamentosa (Goeze, 1782) (Dilepididae); and 9 nematodes - Capillaria talpae (Siebold, 1850), Eucoleus oesophagicola Sołtys, 1952, Liniscus incrassatus (Diesing, 1851), Trichuris feliui Ribas et Casanova, 2004 (Trichuridae), Parastrongyloides winchesi Morgan, 1928 (Strongyloididae), Porrocaecum spp. larvae (Ascarididae), Spirura talpae (Gmelin, 1790) (Spiruridae), Tricholinstowia linstowi (Travassos, 1918) and T. mornanti Durette-Desset et Vaucher, 1974 (Heligmonellidae). In the general helminth fauna, S. talpae was found the most prevalent species (43.9%) and with the highest infection intensity. Prevalences of l. lorum, L. incrassatus, Porrocaecum spp. and T. mornanti ranged from 9.7 to 17.5% and mean intensities between 1.4 and 2.3. L. capillaris, Porrocaecum spp., S. talpae and T. mornanti are core species in the helminth community of T. europaea. The rest of species are considered satellite. All the species found in males are present in females except E. oesophagicola. No significant differences were found between males and femaks in quantitative parameters. Values of Lefkovitch's index indicate a negative binomial distribution for all species. Correlation between altitude of the biotopes and species richness was not significant. Qualitative and quantitative data were compared with other known helminthological studies of Talpa spp. in Europe.

nr 3

A total of 51 and 21 adults of Barbary ground squirrels (Atlantoxerus getulus) were trapped during May–July 2006 from the introduced populations on Fuerteventura Island (Canary Islands) and the native populations in Morocco, respectively. One trematode, 1 cestode and 4 nematode species were recovered belonging to five families: Brachylaima sp. (Brachylaimidae), Catenotaenia chabaudi (Catenotaeniidae), Protospirura muricola (Spiruridae), Dermatoxys getula and Syphacia pallaryi (Oxyuuridae), and Trichostrongylus sp. (Trichostrongylidae). We report for the first time the presence of P. muricola, Trichostrongylus sp. and Brachylaima sp. in A. getulus. Brachylaima sp. was found in the insular population only, as a result of a diet that includes snails. The two oxyurids were found at both sites. The continental population showed higher species richness (5 vs 3 species). This is the first report of helminth parasites from A. getulus from the Canary Islands.
