Summary Hibernation is the most effective means for energy conservation during winter in mammals. The drawbacks of deep and prolonged torpor include reduced immunocompetence, consequently, hibernators should be selected to minimize expression when climatic conditions or availability (e.g. food fat stores) permit. Therefore, it seems surprising that some employ extraordinary long hibernation seasons, lasting well beyond periods with unfavourable conditions. Because their extended use torpor,...
• Prevalence of ESBL/pAmpC-producing E. coli is highest in chicken meat. Characteristics isolates from turkey meat are significantly different to those chicken. CTX-M group among the ESBL/pAmpC producing was (26.0%) and (24.0 %). Minced beef or pork contaminated at higher frequency than pork. Vegetables only a very low level Germany. The spread extended-spectrum β-lactamases (ESBLs) Escherichia major public health issue ESBL-producing bacteria frequently reported livestock. For assessment...

West Nile virus (WNV) is becoming more widespread and markedly effecting public health. We sequenced the complete polyprotein gene of a divergent WNV strain newly detected in pool Uranotaenia unguiculata mosquitoes Austria. Phylogenetic analyses suggest that new constitutes ninth lineage or sublineage 4.
Culex pipiens/restuans mosquitoes are important vectors for a variety of arthropod borne viral infections. In this study, the associations between 20 years mosquito capture data and time lagged environmental quantities daytime length, temperature, precipitation, relative humidity wind speed were used to generate predictive model population dynamics vector species. Mosquito in study area was represented by averaged series mosquitos counts captured at 6 sites Cook County (Illinois, USA)....
Understanding how local environmental factors lead to temporal variability of vital rates and plasticity life history tactics is one the central questions in population ecology. We used long-term capture-recapture data from five populations a small hibernating rodent, edible dormouse Glis glis, collected over large geographical range across Europe, determine analyze both seasonal patterns survival their relation reproductive activity. In all studied, was lowest early summer, higher late...
<title>Abstract</title> Mosquitoes harbour diverse bacterial communities that are influenced by a number of factors, e.g., geography, host species, and developmental stage. Understanding these microbiotas is crucial for assessing their role as vectors in pathogen dissemination. Here, we compared the <italic>Aedes albopictus</italic> japonicus</italic> across eight countries: six Europe, plus USA Japan, from both adults larval stages when possible, using 16S rRNA amplicon sequencing. We found...
The edible dormouse is a specialized seed predator which highly adapted to the fluctuations of food availability caused by mast seeding beech and oak trees. Dormice produce young just in time with maximum availability, can completely skip reproduction years lack seeding. Because their decision reproduce or not any particular year made long before ripe seeds are available, it seems that dormice anticipate upcoming situation. We tested hypothesis presence high caloric spring affects...
The study describes the estimation of spatial distribution questing nymphal tick densities by investigating Ixodes ricinus in Southwest Germany as an example. production high-resolution maps is important key to quantify risk tick-borne diseases. Previous I. were based on quantitative well semi-quantitative categorisations density observed at sites with different vegetation types or indices, all compiled local scales. Here, a approach landscape scale introduced. During 2 years, 2013 and 2014,...
Insect vectors, namely mosquitoes (Diptera: Culicidae), are compulsory for malaria parasites (Plasmodium spp.) to complete their life cycle. Despite this, little is known about vector competence of different mosquito species the transmission avian parasites.In this study, nested PCR was used determine Plasmodium spp. occurrence in pools whole individuals, as well diversity mitochondrial cytochrome b gene sequences wild-caught sampled across Eastern Austria 2013-2015.A total 45,749 2628 were...
Mosquitoes (Diptera: Culicidae) are important vectors for a wide range of pathogenic organisms. As large parts the human population in developed countries live cities, occurrence vector-borne diseases urban areas is particular interest epidemiologists and public health authorities. In this study, we investigated mosquito city Vienna, Austria, order to estimate risk transmission mosquito-borne diseases. were captured using different sampling techniques at 17 sites Vienna. Species belonging...
Trypanosomatid flagellates have not been studied in Austria any detail. In this study, specific nested PCR, targeted on the ribosomal small subunit, was used to determine occurrence and diversity of trypanosomatids wild-caught mosquitoes sampled across Eastern years 2014−2015. We collected a total 29,975 19 species divided 1680 pools. Of these, 298 (17.7%), representing 12 different mosquito species, were positive for trypanosomatid DNA. total, seven spp. identified (three Trypanosoma, three...
Abstract Millions of people die each year as a result pathogens transmitted by mosquitoes. However, the morphological identification mosquito species can be difficult even for experts. The morphologically indistinguishable species, such members Anopheles maculipennis complex (Diptera: Culicidae), and possible hybrids, Culex pipiens pipiens/ molestus presents major problem. In addition, detection discrimination newly introduced challenging, particularly to researchers without previous...
This study was designed to evaluate the costs between 2005 and 2013 of national bluetongue virus (BTV) surveillance vaccination programmes before, during after BTV serotype 8 (BTV-8) outbreak in Austria commencing 2008. In addition an assessment temporal development costs, a spatial cost analysis performed. Within context this study, term 'costs' refers actual financial expenditure imputed monetary for contributions in-kind. Costs were financed directly by private-public sectors, European...

The administration of antibiotics to farm animals is an important contemporary topic. Veterinarians, pig producers, politicians, retailers and consumers all have a vested interest in reducing antimicrobial use on farm, while ensuring adequate health welfare food‐producing animals. Vaccination programmes may be used reduce the overall level clinical disease population, subsequently leading decline use. In 2008, vaccination programme against porcine circovirus type 2 (PCV‐2) was initiated...
Canine and feline cardiorespiratory parasites are of utmost relevance in veterinary medicine. Key epizootiological information on major pet metastrongyloids, i.e., Angiostrongylus vasorum Crenosoma vulpis infecting dogs, Aelurostrongylus abstrusus Troglostrongylus brevior cats, is missing from Austria. This study investigated their occurrence 1320 gastropods collected the Austrian provinces Styria, Burgenland, Lower Austria, metropolitan Vienna. Metastrongyloid larvae were microscopically...
Human and animal vector-borne diseases, particularly mosquito-borne are emerging or re-emerging worldwide.

Edible dormice (Glis glis) are exposed temporally and spatially to a tremendous variation in food resources. This strongly influences reproduction; edible reproduction is tightly linked the availability of energy-rich seeds. Although most reproduce full mast years beech or oak, entire populations skip without seed production; however, nearly 50% all intermediate years, during which only part dormouse population reproduces. We investigated how pattern, local habitat characteristics,...
