69 Preliminary data about the parasitism caused by Protozoa, Helminths and Ticks in cervids and wild bovids from Salamanca (western Spain). Ramajo Martín, V.; Pérez Sánchez, R.; Ramajo Hernández, A.; Oleaga, A. Instituto de Recursos Naturales y Agrobiología de Salamanca (CSIC). Unidad de Patología Animal. 37008 Salamanca. Received: 30.01.06 DEDICATORIA: Accepted: 03.07.06 A la memoria de Ignacio Navarrete López-Cózar, parasitólogo de vocación, que siempre se sintió fascinado por la parasitología de la fauna silvestre. Summary: A parasitological screening was carried out on faeces and cadavers (n=38) from wild animals shot in the Las Batuecas National Reserve and in some private game reserves of the Salamanca province (Spain). The following parasites were identified: Babesia/Theileria spp . Were found in red deer, fallow deer and mouflon. Sarcocystis spp . Was found in roe deer, fallow deer, mouflon, red deer and Spanish ibex. Eimeria spp . In Spanish ibex, mouflon, roe deer and red deer. Cryptosporidium spp. Was found in fallow deer, mouflon and red deer. Dicrocoelium dendriticum was found in red deer, fallow deer and mouflon. Paramphistomum cervi was found in red deer. Moniezia spp . Was present in Spanish ibex, fallow deer, roe deer and red deer and Echinococcus hydatidosus was detected in male Spanish ibexes. Elaphostrongylus cervi in roe deer and red deer. Cystoculus ocreatus in Spanish ibex and Protostrongylus/Muellerius in roe deer, red deer, fallow deer and mouflon. Gastrointestinal nematodes appeared in nearly 100% of the animals: Ostertagia spp. In red deer; Spiculopteragia asymmetrica in fallow deer; Teladorsagia davtiani in roe deer; T. circumcincta in mouflon, red deer, Spanish ibex; Trichostrongylus axei in mouflon, red deer and roe deer; T. vitrinus, Cooperia oncophora and Oesophagostomum venulosum in mouflon; Nematodirus filicollis in roe deer, N. spathiger in mouflon and red deer; Cappillaria sp . In red deer and Trichuris ovis in whole host species. Hard ticks were removed from red deer ( Haemophysalis punctata and Ripicephalus bursa ) and fallow deer ( Ixodes ricinus ). In the Salamanca province all these wild ruminants share epidemiological links with domestic ruminants bred in extensive-system farms. Key words: cervids, wild bovids, parasites, Salamanca province (Spain). Resumen: Se estudian heces y 38 cadáveres de animales abatidos en caza en la Reserva Regional de Las Batuecas y cotos privados de Salamanca. La parasitofauna registrada fue la siguiente: Piroplasmas sin determinar (Babesia/Theileria) aparecieron en ciervo, gamo y muflón. Sarcocystis spp . en corzo, gamo, muflon, ciervo y cabra montés. Eimeria spp. en cabra montés, muflón, corzo y ciervo. Cryptosporidium spp. en gamo, muflón y ciervo. Dicrocoelium dendriticum en ciervo, gamo y muflón, y Paramphistomum cervi en cier - vo. Moniezia spp . en cabra montés, gamo, corzo y ciervo, y Echinococcus hydatidosus en macho montés. Protostrongylidae extrapulmo - nares ( Elaphostrongylus cervi ) en corzo y ciervo. Protostrongylidae pulmonares en cabra montés ( Cystocaulus ocreatus ), corzo, ciervo, gamo y muflón ( Protostrongylus/Muellerius ). Nematodos gastroentéricos en prácticamente el 100% de los animales: Ostertagia spp . en ciervo; Spiculopteragia asimétrica en gamo; Teladorsagia davtiani en corzo; T. circumcincta en muflón, ciervo y cabra montés; Trichostrongylus axei en muflón, ciervo y corzo; T. vitrinus , Cooperia oncophora y Oesophagostomum venulosum en muflón; Nematodirus filicollis en corzo; N. spathiger en muflón y ciervo; Capillaria sp . en ciervo y Trichuris ovis en todas las especies hospeda - doras. Garrapatas se localizaron en ciervos ( Haemophysalis punctata y Ripicephalus bursa ) y gamos ( Ixodes ricinus ). En el área salman - tina, estos animales comparten vínculos epidemiológicos con los rumiantes domésticos de explotación extensiva .
