Summary Forty‐three association (similarity) coefficients were collected and evaluated in this survey.

Two Gram-negative, non-motile, non-spore-forming, coccoid bacteria (strains CCM 4915T and 4916), isolated from clinical specimens of the common vole Microtus arvalis during an epizootic in Czech Republic 2001, were subjected to a polyphasic taxonomic study. On basis 16S rRNA (rrs) recA gene sequence similarities, both isolates allocated genus Brucella. Affiliation Brucella was confirmed by DNA–DNA hybridization studies. Both strains reacted equally with M-monospecific antiserum lysed...
In the last 30 years several cases of West Nile (WN) virus infection were reported in horses and humans Europe Mediterranean Basin. Most them determined by strains Lineage 1 included European Mediterranean/Kenyan cluster. Strains this cluster are characterised a moderate pathogenicity for limited or no birds. recent years, however, WN grouped Israeli/American lineage 2 have been Hungary Austria. The role migrating birds introducing new viruses to has often demonstrated. migratory birds,...
A flavivirus (strain 97-103) was isolated from Culex pipens mosquitoes in 1997 following floods South Moravia, Czech Republic. The strain exhibited close antigenic relationship to West Nile virus (WNV) prototype Eg-101 a cross-neutralization test. In this study, mouse pathogenicity characteristics and the complete nucleotide putative amino acid sequences of isolate 97-103, named Rabensburg (RabV) after nearby Austrian city, were determined. RabV shares only 75%-77% identity 89%-90% with...
West Nile virus was first recorded in the New World during August 1999 York City. Aetiology of disease Old indicated birds as likely introductory and amplifying hosts with ornithophilous mosquitoes, e.g. Culex pipiens, principal vectors. Speculation regarding agents for movement its new environment focused on migratory birds, but evidence to date is equivocal. While spread has been fairly rapid, at a rate roughly 70 km month, it not shown kind long-distance, leap frog movements one might...
Arthropod-borne flaviviruses are human pathogens of global medical importance, against which no effective small molecule-based antiviral therapy has currently been reported. Arbidol (umifenovir) is a broad-spectrum compound approved in Russia and China for prophylaxis treatment influenza. This shows activities numerous DNA RNA viruses. The mode action based predominantly on impairment critical steps virus-cell interactions. Here we demonstrate that arbidol possesses micromolar-level...
West Nile virus (WNV) is currently the most important mosquito-borne pathogen spreading in Europe. Data on overwintering of WNV mosquitoes are crucial for understanding circulation Europe; nonetheless, such data were not available so far.A total 28,287 hibernating [27,872 Culex pipiens, 73 Anopheles maculipennis (sensu lato), and 342 Culiseta annulata], caught February or March between 2011 2017 a WNV-endemic region South Moravia, Czech Republic, screened presence RNA. No positive pools...
Background White-nose syndrome is a disease of hibernating insectivorous bats associated with the fungus Geomyces destructans. It first appeared in North America 2006, where over million died since then. In Europe, G. destructans was identified France 2009. Its distribution, infection dynamics, and effects on Europe are largely unknown. Methodology/Principal Findings We screened hibernacula Czech Republic Slovakia for presence during winter seasons 2008/2009 2009/2010. 2009/2010, we found...
To determine which kind of spirochete infects larval Ixodes ricinus, we examined questing larvae and derived from engorged females for the presence particular spirochetal DNA that permitted species differentiation. Borrelia miyamotoi was sole detected in ticks sampled while on vegetation. Questing nymphal adult were infected mainly by afzelii, whereas resulting same population solely B. miyamotoi. Since acquire Lyme disease spirochetes within a few hours attachment to an rodent, nature may...
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.
Tick-borne encephalitis (TBE) is a viral disease endemic in Eurasia. The virus mainly transmitted to humans via ticks and occasionally the consumption of unpasteurized milk products. European Centre for Disease Prevention Control reported an increase TBE incidence over past years Europe as well emergence new areas. To better understand this phenomenon, we investigated drivers through expert knowledge elicitation. We listed 59 possible grouped eight domains elicited forty experts to: (i)...
