Filarioid parasites represent major health hazards with important medical, veterinary, and economic implications, considerable potential to affect the everyday lives of tens millions people globally (World Health Organization, 2007). Scenarios for climate change vary latitudinally regionally involve direct indirect linkages increasing temperature dissemination, amplification, invasiveness vector-borne parasites. High latitude regions are especially influenced by global thus may be prone...
Abstract Background During seasonal round-ups, free-grazing reindeer are gathered from natural pastures. Reindeer bulls removed breeding clamp castrated, traditionally without analgesia, and then returned to the grazing grounds. The new Finnish Animal Welfare Act requires use of analgesia in painful procedures. Our earlier studies have shown that a single dose non-steroidal anti-inflammatory drug (NSAID) meloxicam may maintain therapeutic plasma concentrations for 2–3 days reindeer. No been...
In 2003, there was an outbreak of peritonitis in reindeer the southern and middle part Finnish herding area caused by filarioid nematode Setaria species. province Oulu, proportion viscera condemned owing to parasitic lesions increased from 4·9 per cent 2001 40·1 2003. 2004, focus moved approximately 100 km north. A total 260 adult pre‐adult species nematodes were collected for morphological molecular studies. The parasite indistinguishable terms morphology biology tundra . Samples parasites...
Recent studies have revealed expansion by an array of Filarioid nematodes' into the northern boreal region Finland. The vector-borne nematode, Setaria tundra, caused a serious disease outbreak in Finnish reindeer population 2003–05. main aim this study was to understand dynamics and rapid S. tundra sub arctic. We describe vectors its development vectors, for first time. Finally we discuss results context host-parasite ecology Finland Development infective stage occurs mosquitoes, (genera...
Climate oscillations and episodic processes interact with evolution, ecology biogeography to determine the structure complex mosaic that is biosphere. Parasites parasite-host assemblages are key components in a general explanatory paradigm for global biodiversity. We explore faunal assembly context of Quaternary time frames past 2.6 million years, period dominated by shifts climate. drivers cross continuum from geological contemporary timescales serve distribution biotas. Cycles within...
Abstract Aim Moose, Alces alces (Linnaeus, 1758), survived the European Pleistocene glaciations in multiple southern refugia, a northern refugium near Carpathians and possibly other locations. During second millennium ad , moose were nearly extirpated Europe only recolonized their current range after World War II . The number location of refugia during recent population lows may have affected genetic diversity. We sought to characterize diversity order determine its structure hotspots as way...
The spread of vector-borne diseases to new regions has become a global threat due climate change, increasing traffic, and movement people animals. Dirofilaria repens, the canine subcutaneous filarioid nematode, expanded its distribution range northward during last decades. northernmost European locations, where parasite life-cycle been confirmed, are Estonia Novgorod Region in Russia. Herein, we describe an autochthonous D. repens infection Finnish woman. We also present two cases imported...
The species Echinococcus granulosus is made up of several genotypic strain groups, whose taxonomical classification still undetermined. Genotypes in the cervid-wolf life-cycle are poorly known, especially Europe. In this study, 33 isolates from cervids Finland and Sweden were characterized using mitochondrial ND1 gene sequencing. addition, phylogenetic analysis E. strains ATP6, ND1, ND3 CO1 genes was performed maximum likelihood, neighbour-joining parsimony methods. Finnish Swedish cervid...
Abstract The deer ked ( Lipoptena cervi ) can fail in its host search. Host search fails when an individual irreversibly accepts a unsuitable for reproduction (e.g. human) and drops wings. In northern Europe, the main of is moose Alces alces ). increasingly causing serious problems humans (for example, dermatitis) considered threat recreational use forests. adult flies early mid-autumn to host. Our aims were: (i) study whether there are ways avoid attacks by wearing particular clothing, (ii)...
The range expansion of organisms towards higher latitudes and altitudes is often limited by colder temperatures the shorter growth season. In parasites, survival outside host most likely to affect their potential establishment in novel environments. We conducted a large scale transplant experiment predict spread deer ked Lipoptena cervi (Diptera: Hippoboscidae), blood‐feeding ectoparasite boreal cervids. studied off‐host pupal development five sites along latitudinal gradient reaching from...
The Finnish and Russian animal species (semi-domesticated reindeer, wild moose, Baltic grey seal herring) samples were biomonitored in terrestrial aquatic environments for polychlorinated dibenzo-p-dioxins dibenzofurans (PCDD/Fs), biphenyls (PCBs) polybrominated diphenylethers (PBDEs). Grey (Halichoerus grypus) was clearly the most contaminated species. mean PBDE concentration 115 ng/g fat, highest WHO-PCDD/F-PCB-TEQ (toxic equivalent set by WHO) 327 pg/g fat. In Finnish, reindeer...
Hunting is currently a very popular activity, and interest in game meat increasing. However, only limited research available on the bacterial quality safety of moose (Alces alces) white-tailed deer (Odocoileus virginianus) harvested by hunters. Poor hunting hygiene can spread bacteria onto carcasses, inadequate chilling carcasses may increase load carcass surface. We studied contamination level 100 shot southern Finland. Hunters eviscerated field skinned them small slaughter facilities....
Infectious keratoconjunctivitis (IKC) is one of the most common ocular diseases in ruminants worldwide. In addition to keratitis and conjunctivitis, animals with IKC can develop uveitis, corneal ulcer, severe cases, blindness. The bacteria Moraxella spp. has been described as primary causative agent infectious bovine (IBK) cattle (Bos taurus), while Chlamydia Mycoplasma conjunctivae are considered main agents sheep (Ovis aries). Previous studies indicated cervid herpesvirus 2 (CvHV2)...
Recent studies revealed expansion of filarioid nematodes into northern Finland. In addition to Setaria tundra, an abundant filarioid, Rumenfilaria andersoni, was found inhabiting the lymphatic vessels reindeer. Our study explores dynamics rapid geographic R. defining prevalence and density microfilariae among 4 new cervid host species in Finland while developing a context for host-parasite ecology Fennoscandia more broadly Arctic boreal regions.
To investigate genetic diversity and the population structure of European moose (Alces alces), we analyzed 14 microsatellite loci for 694 samples collected across 16 localities. The highest was detected in Belarus Russia lowest found Scandinavia. Two major clusters existed, Scandinavian continental, some further spatial detected. There high concordance between distribution present study previously recognized mitochondrial DNA clades moose. split lineages calculated using approximate Bayesian...
In autumn 2006, Finnish meat inspection data revealed lesions in tendons, muscles and ligaments of bovine hind legs leading to partial condemnation carcasses. gross pathological examination at Food Safety Authority Evira, Oulu (now Fish Wildlife Health) Research Unit, Onchocerca sp. (Filarioidea; Onchocercidae) nematodes were detected lesions. Due this, a pilot study was made order find out what filarioid do occur cattle, horses sheep Finland.Ventral skin biopsies from 209 dairy cattle 42...
