Experimental infection of the deer ked (Lipoptena cervi) has no negative effects on the physiology of the captive reindeer (Rangifer tarandus tarandu…

2011

The deer ked (Lipoptena cervi) is a haematophagous parasitic fly of cervids that spread to Finland in the early 1960's. Presently its northern distribution limit lies at approximately 65°N and it is gradually spreading northwards. In Finland the principal host species has been the moose (Alces alces), but the deer ked is about to establish contact with another potential host, the semi-domesticated reindeer (Rangifer tarandus tarandus) causing possible threats to reindeer health and management. The aim of this study was to investigate if the deer ked would have an influence on the welfare of the reindeer. Eighteen adult reindeer were divided into three experimental groups: the control group …

Do bank voles (Myodes glareolus) trapped in live and lethal traps show differences in tick burden?

2020

In studies assessing tick abundance, the use of live traps to capture and euthanize rodent hosts is a commonly used method to determine their burden. However, captive animals can experience debilitating or fatal capture stress as a result prior to collection. An alternative method is the use of lethal traps, but this can potentially lead to tick drop-off between the time of capture and collection. In this study, in order to determine whether subjecting animals to capture stress is inevitable, we tested the difference in sheep tick (Ixodes ricinus) larval burdens between bank voles (Myodes glareolus) captured alive and euthanized, and lethally trapped bank voles. During 2017 and 2018, 1318 b…

Comparison of three different staining methods for the assessment of epididymal red deer sperm morphometry by computerized analysis with ISAS®

2005

When collection of ejaculated sperm samples is not possible, as is the case with wild species, the epididymides of sacrificed wild males become the only possible source of spermatozoa. Mature cauda epididymal spermatozoa display characteristics similar to those of ejaculated sperm cells. The present work proposes a sperm staining technique suitable for the morphometric evaluation of red deer epididymal sperm using a new computerized system. Epididymides from wild animals were extracted no later than 2 h post mortem. After epididymal sectioning, sperm samples were collected, cooled to and equilibrated at 5 °C, and frozen in liquid nitrogen. Before staining, sperm samples were thawed for 20 s…

Genetic characterization of Anaplasma phagocytophilum strains from goats (Capra aegagrus hircus) and water buffalo (Bubalus bubalis) by 16S rRNA gene…

2019

Anaplasma phagocytophilum is a Gram-negative obligate intracellular bacterium that replicates in neutrophil granulocytes. It is transmitted by ticks and causes tick-borne fever in domestic ruminants such as sheep, cattle and goats. However, in contrast to sheep and cattle little is known about the clinical course of infection in goats. We report here on three cases of symptomatic infection with A. phagocytophilum in two goats (Capra aegagrus hircus) and one water buffalo (Bubalus bubalis). The animals showed symptoms and laboratory findings similar to sheep and cattle. To our knowledge, this is the first report on the symptomatic infection of water buffalos with A. phagocytophilum. The infe…

Detection of Anaplasma phagocytophilum in Wild and Farmed Cervids in Poland

Background: The role of cervids in the circulation of A. phagocytophilum has not yet been clearly determined

Brominated flame retardants and toxic elements in the meat and liver of red deer (Cervus elaphus), wild boar (Sus scrofa), and moose (Alces alces) fr…

2017

In order to evaluate the contamination status of terrestrial biota in Latvia, muscle and liver tissues of red deer (Cervus elaphus), wild boar (Sus scrofa), and moose (Alces alces) were analyzed for the content of polybrominated diphenyl ethers (PBDE), hexabromocyclododecane (HBCD), tetrabromobisphenol A (TBBPA), as well as cadmium and lead. The highest mean concentrations of PBDEs (46.6pgg-1 wet weight (w.w.)), cadmium (0.95mgkg-1 w.w.), and lead (0.22mgkg-1 w.w.) were observed in the tissues of moose, while the wild boar samples contained the highest levels of HBCD, with the mean concentration equal to 264pgg-1 w.w. in muscle tissues. Generally low mean concentrations of TBBPA from 0.52 t…

Exploring the mechanisms by which reindeer droppings induce fen peat methane production

2021

Abstract Peatlands, especially fens, are known to emit methane. Reindeer (Rangifer tarandus) use mires mainly as spring and summer pastures. In this work we observed that adding reindeer droppings to fen peat increased the potential methane production by 40%. This became apparent when droppings originating from reindeer kept in pen or pasture in winter were added to methanogenic fen peat samples. The droppings introduced Methanobacteriaceae (Methanobrevibacter; > 90% of the mcrA MiSeq reads) to the peat, which was originally populated by Methanosarcinaceae, Methanosaetaceae, Methanoregulaceae, Methanobacteriaceae, Methanomassiliicoccaceae, Methanocellaceae and Methanomicrobiaceae. The origi…

A revision of medium and small sized deer from the Middle and Late Pleistocene of Calabria and Sicily

2001

The remains of Megaceroides calabriae from Middle Pleistocene deposits at locality Bovetto (Southern Calabria) and of Megaceroides carburangelensis from the late Middle and Late Pleistocene locality Cimillà (South-eastern Sicily) are revised. These deer were considered as endemic species of strongly reduced size, related to genus Megaceroides (=Praemegaceros), which evolved in insular environment similarly to the endemic megaceroids from Sardinia, Corsica and Crete, M, cazioti and M. cretensis. The comparison of M. calabriae and M. carburangelensis with representatives of genera Megaceroides and Dama, carried out in the present study, shows that the Calabrian and Sicilian deer belong to Dam…

Diagnostic polymorphisms in the mitochondrial cytochrome b gene allow discrimination between cattle, sheep, goat, roe buck and deer by PCR-RFLP

2004

Abstract Background As an alternative to direct DNA sequencing of PCR products, random PCR-RFLP is an efficient technique to discriminate between species. The PCR-RFLP-method is an inexpensive tool in forensic science, even if the template is degraded or contains only traces of DNA from various species. Results Interspecies-specific DNA sequence polymorphisms in the mitochondrial cytochrome b gene were analyzed using PCR-RFLP technology to determine the source (i.e., species) of blood traces obtained from a leaf. Conclusions The method presented can be used for the discrimination of cattle (Bos taurus), sheep (Ovis aries), goat (Capra hircus), roe buck (Capreolus capreolus) and red deer (Ce…
