“…Overall, the endoparasites found in our study are widely distributed and have been described for other deer species and domestic ruminants worldwide (Duarte et al, 2001;Hoberg et al, 2001). Amongst gastrointestinal parasites found in our study, only Ostertagia spp.…”

ABSTRACT:Samples from 14 free-ranging pampas deer (Ozotoceros bezoarticus celer) were collected in 1995 and 1998, at Campos del Tuyú Wildlife Reserve, Buenos Aires, Argentina. Hematology, serum chemistries, minerals and metals, and fecal parasites were analyzed. In addition, fecal ova and parasites were evaluated seasonally during 1998-2000. Serology for infectious diseases included bluetongue, brucellosis, bovine respiratory syncytial virus infection, bovine viral diarrhea/mucosal disease, infectious bovine rhinotracheitis, Johne's disease (paratuberculosis), foot and mouth disease (FMD), leptospirosis (eight serovars), epizootic hemorrhagic disease, and parainfluenza-3 (PI-3). Three (21%) pampas deer had antibodies to Leptospira spp. and six (43%) to PI-3 virus. Serologic results for all other infectious agents were negative. Domestic cattle (nϭ27) included in this study for comparison had antibodies to Leptospira, infectious bovine rhinotracheitis virus, bovine viral diarrhea virus, and PI-3 virus (74-100% of tested animals) and one animal (4%) to Brucella sp. All cattle had antibodies to FMD virus attributable to vaccination. This study provides the first data on the health status of the southernmost subspecies of pampas deer.

“…This serves to emphasize the pervasive nature of anthropogenic events, particularly conservationbased or management-based decisions for translocation that may influence the overall distribution of parasites and pathogens. These observations constitute a strong justification for development of baselines and archival collections for biodiversity to document faunal perturbation (e.g., Hoberg et al, 2001Hoberg et al, , 2003.…”

“…Such dorsal spined larvae (DSLs) recovered from feces cannot be reliably identified based on morphology, and polymorphism among larvae of some species has been noted (Hoberg et al, 2005). The advent of molecularbased methods has altered our approach to survey and inventory for protostrongylid and other nematodes in ungulates (e.g., Hoberg et al, 2001). Sequence data from individual DSL assessing both nuclear and mitochondrial loci are now used as epidemiologic probes to explore identity, distribution, and phylogeography based on geographically extensive and site intensive sampling (e.g., Jenkins et al, 2005;Mortenson et al, 2006;Kutz et al, 2007;Hoberg et al, unpubl.…”

ABSTRACT:Parelaphostrongylus andersoni is considered a characteristic nematode infecting white-tailed deer (Odocoileus virginianus). Host and geographic distribution for this parasite, however, remain poorly defined in the region of western North America. Fecal samples collected from Columbia white-tailed deer (O. v. leucurus) in a restricted range endemic to Oregon and Washington, USA, were examined for dorsal-spined larvae characteristic of many protostrongylid nematodes. Multilocus DNA sequence data (internal transcribed spacer 2 and cytochrome c oxidase subunit 1) established the identity and a new record for P. andersoni in a subspecies of white-tailed deer previously unrecognized as hosts. Populations of P. andersoni are now recognized along the basin of the lower Columbia River in Oregon and Washington and from south-central Oregon on the North Umpqua River. Current data indicate a potentially broad zone of sympatry for P. andersoni and Parelaphostrongylus odocoilei in the western region of North America, although these elaphostrongylines seem to be segregated, respectively, in white-tailed deer or in black-tailed and mule deer (Odocoileus hemionus) at temperate latitudes. The geographic range for P. andersoni in white-tailed deer is extended substantially to the west of the currently defined limit in North America, and we confirm an apparently extensive range for this elpahostrongyline. These observations are explored in the broader context of host and geographic associations for P. andersoni and related elaphostrongylines in North American cervids.

“…Eggs identi ed as having typical 'strongyle-egg' morphology can belong to a number of di erent genera, however in arctic and subarctic environments the abomasal nematodes Ostertagia gruehneri and Teladorsagia boreoarcticus are the most common in Rangifer sp. (Hoberg et al, 2001;Kutz et al, 2012). Also producing 'strongyle-type' eggs, Teladorsagia circumcincta has been previously reported in KS by Korsholm & Olesen (1993).…”
