| spiculopteragia spiculoptera, s. asymmetrica and ostertagia leptospicularis from cervus elaphus in la pampa, argentina. | the nematode species spiculopteragia spiculoptera, spiculopteragia asymmetrica and ostertagia leptospicularis were recovered from the abomasum of wild red deer, cervus elaphus, in the forest area of the semi-arid pampeana region of la pampa (argentina) for the first time. oesophagostomum venulosum and dictyocaulus spp. were also found. | 1991 | 1763487 |
| the identification of females within the subfamily ostertagiinae lopez-neyra 1947. | as a result of the examination of many thousands of female nematodes classified as belonging to the sub-family ostertagiinae lopez-neyra 1947, it became possible to compile descriptions of different female types, each of which corresponds to a polymorphic species as determined by male morphology. the female types have been designated as follows: ostertagia ostertagi (males o. ostertagi and o. lyrata), ostertagia circumcincta (males o. circumcincta, o. trifurcata and teladorsagia davtiani), oster ... | 1990 | 2343529 |
| gastro-intestinal nematodes of fallow deer (dama dama l.) in germany. | worm counts were done in 49 gastro-intestinal tracts of fallow deer from two german enclosures. the mean worm burden was 592 worms. it was significantly higher in calves than in older animals. sixteen different nematode species were identified. spiculopteragia asymmetrica, ostertagia leptospicularis, o. ostertagi, rinadia mathevossiani, oesophagostomum radiatum and o. venulosum were the most frequently occurring species. | 1984 | 6543050 |
| [first sign in italy of nematodirus roscidus, apteragia quadrispiculata and ostertagia drozdzi, found in dama dama]. | the authors refer the first report in italy of nematodirus roscidus railliet, 1911, apteragia quadrispiculata jansen, 1958 and ostertagia drozdzi jancev, 1977 from dama dama. in fallow deer they found also: trichostrongylus axei, trichostrongylus colubriformis, trichostrongylus vitrinus, spiculopteragia asymmetrica, skrjabinagia arctica, oesophagostomum venulosum, trichuris ovis. trichostrongylus axei, trichostrongylus colubriformis, trichostrongylus vitrinus and skrjabinagia arctica were not fo ... | 1983 | 6543932 |
| [possibilities of contagion of gastrointestinal and lung nematode infections of fallow deer for cattle, sheep and goats raised in the same fenced area as fallow deer]. | cattle as well as sheep and goats may be infected with parasitic nematodes of fallow deer under natural conditions, but heavy infections do not occur. most nematode species were recorded in goats, cattle harboured the fewest number of species. the specific abomasal parasites of fallow deer (spiculopteragia asymmetrica, apteragia quadrispiculata, skrjabinagia ryjikovi, ostertagia drozdzi) were only seen in goats in greater number while both cattle and sheep were only poor susceptible. capillaria ... | 1994 | 7720543 |
| the systematics of nematodes that cause ostertagiasis in domestic and wild ruminants in north america: an update and a key to species. | studies of medium stomach worms (subfamily ostertagiinae) of domestic and wild ruminants in north america have refined our understanding of the systematics, host distribution and biogeography of these nematodes. strong support for recognition of monophyly for the ostertagiinae has resulted from preliminary phylogenetic analyses of morphological characters among these and other trichostrongylids. evaluation of morphological and biochemical characters in our laboratory and elsewhere has not refute ... | 1993 | 8484224 |
| pattern of abomasal helminths in fallow deer farming in umbria (central italy). | five helminth species were seen in the abomasa of 29 farmed fallow deer. spiculopteragia asymmetrica was most common in both prevalence (96.6%) and abundance (166.2). ostertagia drozdzi, ostertagia arctica and spiculopteragia quadrispiculata were also recovered with high prevalence (79.3-93.1%); trichostrongylus axei was sporadic (3.4%). yearlings had worm counts of 496-1480, adult males of 168-1720 and females of 18-2008. for nine of 13 deer, the faecal egg counts were negative and post-mortem ... | 1993 | 8493770 |
| identical its-1 and its-2 sequences suggest spiculopteragia asymmetrica and spiculopteragia quadrispiculata (nematoda: trichostrongylidae) constitute morphologically distinct variants of a single species. | sequences of its-1 and its-2 rdna for adult males of spiculopteragia asymmetrica and spiculopteragia quadrispiculata in red deer (cervus elaphus) were determined. they were found to be identical, suggesting that s. asymmetrica and s. quadrispiculata represent a single species and do not refute the concept of dimorphic species in the spiculopteragia. | 2002 | 12054028 |
| helminths in a giraffe (giraffa camelopardalis xgiraffa) from a zoo in spain. | a pregnant female cape giraffe (giraffa camelopardalis giraffa) died from an unknown cause in the aitana zoo, alicante, spain. neither clinical signs nor macroscopic lesions were observed at necropsy. the alimentary tract was removed and examined for parasites. a total of 2 724 nematodes were found, including camelostrongylus mentulatus, trichostrongylus axei, ostertagia ostertagi, teladorsagia circumcincta, teladorsagia trifurcata, marshallagia marshalli, trichostrongylus vitrinus, trichostrong ... | 2004 | 15373337 |
| age distribution and seasonal dynamics of abomasal helminths in wild red deer from central spain. | a study on age distribution and seasonal dynamics of abomasal helminths in wild red deer was conducted in central spain, by monthly samplings of fawns (<1 yr), subadult (1-2 yr), and adult (>2 yr) animals. both intensity and prevalence of abomasal parasitism were higher in older animals, particularly in males. a bimodal pattern for intensity of infection by gastrointestinal parasites was observed. maximum values attained in winter and summer may be related to variation in climate and the shiftin ... | 2008 | 18576697 |
| population health of fallow deer (dama dama) on little st. simons island, georgia, usa. | fallow deer (dama dama) were introduced to little st. simons island, georgia, usa in the 1920s and thrive at high population densities, to the exclusion of white-tailed deer (odocoileus virginina). the presence of introduced pathogens and parasites as a result of their introduction is currently unknown, as is the impact of native disease on the exotic fallow deer. hunter-killed fallow deer from 2003-2005 were necropsied and surveyed for evidence of infectious disease, parasitic agents, and toxic ... | 2009 | 19395750 |
| endoparasites of the fallow deer (dama dama) of the antheringer au in salzburg, austria. | although the annual harvest of fallow deer increased markedly in austria in the past two decades, only little is known about the parasites of fallow deer in austria. to add current faunistic knowledge on the endoparasites of fallow deer in the country, viscera from six adult males and one male fawn from the game preserve antheringer au, salzburg, were examined in 2009-2010 using standard techniques, and spleen samples were screened for dna of tick-borne pathogens (polymerase chain reaction). inf ... | 2014 | 24535173 |
| spiculopteragia asymmetrica infection in cervus elaphus from iran. | spiculopteragia asymmetrica is a gastrointestinal nematode frequently found in the abomasum of cervids. during december and february 2010, two red deer were died in semeskandeh sanctuary in mazandaran province. moreover, five live deer from mentioned area were treated by ivermectin and collected feces of these animals were used for assessment helminthes infection by parasitological methods. several nematodes were recovered in abomasums and in fecal samples of treated animals. number of worms rec ... | 2014 | 25568698 |
