SNIKAR A SEYðl IFØROYUM 175 Parasites in Sheep in the Faroe Islands Sníkar á seyði í Føroyum Bergur Hanusson Djóralæknatænastan, Varðagøta 85, FO-IOO Tórshavn, Faroe Islands. Phone:+298 315273 Fax:+298 317819 Email: bergurh@post.olivant.fo Úrtak Á heysti 1998 vórðu sýnir tikin av 15 lombum við tí endamáli at staðfesta møguliga sníkufongd. Veturin, várið og heystið 1999 vóru tøðvertir tiknir frá tilsamans 226 lombum og óm. Hesir vórðu kannaðir fyri ormaegg, lungaormalarvur, coccidiuegg og iglaegg. Útvortis- sníkar, funnir í hesum sambandi, vórðu eisini skrásettir. Kanningarnar staðfesta, at seyður í Føroyum er fongdur við niðanfyri nevndu sníkum. Rundormar í vinstur: Teladorsagia circumcincta, T. trifurcata, T. davtiani og Trichostrongylus axei. Rundormar í vilum: Tricho- strongylus vitrinus, Nematodirus battus og N. filicollis. Rundormar í skarngømum: Chabertia ovina, Oeso- phagostomum venulosum og Trichuris ovis. Rundormar í lungum: Dictyocaulus filaria og Muellerius capillaris. Bendilormur í vilum: Moniezia expansa. Bendilormur í búkrúmi: Cysticercus tenuicollis (Taenia hydatigena). Coccidiur í vilum: Eimeria spp. Iglar í livur: Fasciola hepatica. Útvortissníkar: Bovicola ovis (ullalús) og Melophagus ovinus (førilús). Nógv er, sum bendir á, at skrubbmottan, Psoroptes ovis, er á seyði í Føroyum, hóast hon ikki er funnin í hesari kanningini. Úrslitið av hesi verkætlan gevur okkum eina hilling á, hvussu støðan er við sníkum á seyði í Føroyum, men djúptøkn- ari og nágreiniligari kanningar em neyðugar, skulu vit fáa eina hollari fatan av samanspælinum millum sníkar og seyð og av sníkutrupulleikanum sum heild. Abstract In the autumn of 1998, samples from 15 lambs were studied post mortem for the presence of endoparasites. In the winter, spring, and autumn of 1999, faecal sam- ples were collected from 226 lambs and ewes and were searched for the presence of nematode eggs, Eimeria oocysts, lungworm larvae, and Fasciola eggs. Ectopar- asites found in connection with these examinations were also noted. The studies confirm that the following par- asites are present in and on sheep in the Faroe Islands. Nematodes in the abomasum: Teladorsagia circumcinc- ta, T. trifurcata, T. davtiani and Trichostrongylus axei. Nematodes in the small intestine: Trichostrongylus vit- rinus, Nematodirus battus, and N. filicollis. Nematodes in the large intestine: Chabertia ovina, Oesophagosto- mum venulosum, and Trichuris ovis. Nematodes in the lungs: Dictyocaulus filaria and Muellerius capillaris. Cestodes in the small intestine: Moniezia expansa. Ces- todes in the abdominal cavity: Cysticercus tenuicollis (Taenia hydatigena). Coccidia in the small intestine: Eimeria spp. Flukes in the liver: Fasciola hepatica. Ec- toparasites: Bovicola ovis and Melophagus ovinus. There are significant reasons to believe that Psoroptes ovis is also present, although it was not found in this study. It is anticipated that these parasites would have a great impact on the health of the sheep in the Faroe Is- lands, if proper management and medication were not performed. The results of this project contribute to an overall understanding of the parasite population in and on sheep in the Faroe Islands, although extensive study is needed in the future to get a more detailed under- standing of the parasite complex and of the epidemiolo- gy of the same parasites.
