“…This could explain the paucity of exchanges of parasite species between wild and domestic herbivores that other studies have demonstrated in Alpine situations [8,16] in France, [4,21] and in Italy [22]. These exchanges mainly involved Protostrongylids, but also a number of Trichostrongylid species that were not found in this survey.…”

“…The flock then came back down to the 'Esteing' pastures (September 29 -October 14) and 'St Martin d'Entraunes' pastures (October [15][16][17][18][19][20][21][22][23][24][25][26][27]. The meteorological data collected at an altitude of 1640 m gave an average annual rainfall of 1089 mm (51 and 75 mm in July and August respectively), and a monthly mean temperature of -0.2…”

-The aims were to identify the parasite communities and to relate the kinetics of infection to environmental factors during summer transhumance. A survey of parasitism of a sheep flock from the South-East of France was conducted during its summer transhumance in the Southern Alps. The flock was composed of 700 young Merino of Arles ewes. The 152 days of transhumance were spent grazing 3 pastures at an altitude of 1200 m, 4 pastures at 1700 m, and then spending 83 days between 2000 and 2500 m before returning back down to the same groups of lower pastures. The species of parasites present were identified in 5 tracer lambs collected 4 times during the survey. In addition, grass and faecal pellets on the pastures and on 28 alpine grasslands in the upper valley were sampled every month to look for the infective larvae of the gastrointestinal nematodes. Data for these grasslands and their use by the flock were available from the previous year. The main parasite species detected were the nematodes Teladorsagia circumcincta and Nematodirus spp.; the tracers collected about 4000 worms, mainly on the pre-alpine pastures. In the higher valley, considerable differences between the different areas were observed with regards to grass availability, pellet deposition and flock frequency. The pellets acted as a reservoir for over-wintering larvae. The most contaminated areas were those that had been grazed during August of the previous year. These findings were used to optimise flock management so as to limit infection and to prevent deterioration of the higher grasslands due to over-grazing and erosion.sheep / transhumance / nematode parasite / epidemiology / mountain pasture / animal behaviour

“…Among mitochondrial genes, Cytochrome Oxydase I (COX-1) assessed the polymorphism within Teladorsagia spp. [41]. We used mtND4 which exhibits less conservation sites than COX-1 [7] and is often suggested for prospecting closely related species [5,29].…”

“…Our genetic data support this assumption because of the common haplotype found within a red deer and a chamois from the same location. Classified as a specialist parasite, S. spiculoptera is suggested as a marker of interaction between hosts with little medical importance [41]. Its infectivity and its pathogenicity have never been investigated in non-reservoir ruminants.…”

-Although Spiculopteragia spiculoptera is primarily a parasite of cervids, it can also but less often contaminate domestic livestock. Little is known about its epidemiology and its pathogenicity in domestic ruminants and other unusual cervid species. Its taxonomic status remains unclear since the hypothesis of morphological polymorphism among males has been proposed. However, accurate taxonomy is fundamental in the identification and survey of potentially pathogenic species of parasites. The second internal transcribed spacer of rDNA (ITS-2) and the mitochondrial (mt) DNA-derived ND4 gene were used to study the polymorphism hypothesis for S. spiculoptera. ND4 evolves more quickly than ITS-2 and is considered to be more discriminant in the characterization of closely related species. DNA sequences of ITS-2 and ND4 were studied in 18 individual males of morphological type spiculoptera and in 3 of morphological type of mathevossiani from Red deer (Cervus elaphus), Roe deer (Capreolus capreolus) and Chamois (Rupicapra rupicapra). Intraindividual ITS-2 variations were detected within and between each morphotype of Spiculopteragia but these differences did not separate the two morphs mathevossiani and spiculoptera. Similarly, although ND4 showed a high level of nucleotide substitution, the morphotypes S. mathevossiani and S. spiculoptera were clustered together. Our genetic data support the dimorphic male hypothesis for the species S. spiculoptera. mitochondrial DNA / second internal transcribed spacer (ITS-2) / Spiculopteragia spiculoptera / Spiculopteragia mathevossiani / polymorphism

“…Spiculopteragia spiculoptera is a common intestinal nematode of wild ruminants which can be observed rarely from domestic ruminants 16,[18][19][20] . Zaffaroni et al 21 found the frequency of the nematode as 85% in roe deer, 70% in red deer and 8% in mountain goats respectively. Rossi et al 22 reported that S. spiculoptera and Ostertagia leptospicularis, with their "minor" morph S. mathevossiani and O. kolchida were the dominant abomasal species in the roe deer in Italy 22 .…”

SummarySevere injury or dead six roe deer (Capreolus capreolus) which were brought to the clinics of the Faculty of Veterinary Medicine of Ondokuz Mayıs University by Provincial Directorate of Environment and Forest were examined for parasitological at 2007 to 2010. All roe deer were found infected with different gastro intestinal nematodes. Identified 17 nematode species are the first report in roe deer, and also Spiculopteragia spiculoptera and its dimorphic species S. (Rinadia) mathevossiani are the first record in Turkey.
