“…Mouflon is not a competent reservoir host (Gern et al 1998), but showed 16.6% seropositivity. Seroprevalence in mufflons in the Czech Republic was 37.5%, with the highest rate in Bohemia 76.5% (Zeman & Januška 1999). The breed, age and sex of animals did not influence their seroprevalence, however, exposure of animals to ticks infested by borreliae plays a decisive role (Šte-fančíková et al 1996).…”

The paper analyses the results of serological examinations of domestic, farm and free-living animals from different regions of Slovakia, Southern Moravia, Southern Bohemia and Southern Poland using ELISA, indirect hemagglutination assay (IHA) and Western blot (WB). In Slovakia, significantly higher seroprevalence was recorded in dogs (33.5%) than in horses (26.5%), cattle (22.5%), sheep (16.6%) and rodents (17.8%) by using a mixture of Borrelia garinii, B. afzelii, B. burgdorferi sensu stricto (s.s.) antigens in ELISA. Seroprevalence in horses was significantly higher than in sheep and rodents, and seroprevalence in cattle was significantly higher than in rodents. By using IHA in free-living species, the highest seropositivity rates were detected in fallow deer (40.7%) compared with moufflons (16.6%), pheasants (8.0%) and pigeons (1.2%). When testing sera of horses, dogs and cattle from Slovakia by using different Slovak B. burgdorferi sensu lato (s.l.) isolates as antigens in ELISA, significantly higher seroprevalence of anti-Borrelia IgG antibodies and consistency of positive and negative findings was detected in comparison when American isolates were used. In WB analyses using the Eurocarpathian antigens, dog sera from Eastern Slovakia and Southern Moravia showed statistically insignificant differences in sensitivity and consistency of positive and negative findings. By using different methods and antigens in the same group of dog sera, significant differences in seroprevalence were only found in IHA with a mixture of Euroamerican B.b.s.l and WB CB26 B.b.s.s. In addition to other factors, the complexity of the standardization of the assay system with regard to the genetic and geographical heterogeneity of B. burgdorferi s.l. isolates used as antigens is also discussed.

“…ricinus is usually found in vegetation types that maintain high humidity. Woodlands are preferred to open land, with a preference for deciduous compared to coniferous woodlands (Adler, 1992;Glass et al, 1995;Tälleklint 1996;Gray et al, 1998a;Memeteau et al, 1998;Zeman & Januska, 1999). On-going studies show that not only are woodland habitats important but habitat configuration, i.e.…”

“…Important competent reservoirs of B. burgdorferi s.l. in Europe are rodents, such as Apodemus mice and voles; insectivores, such as shrews and hedgehogs; hares; and several bird species, including migratory birds (Aeschlimann et al, 1986;Hovmark et al, 1988;Gern et al, 1991;Matuschka et al, 1992;De Boer et al, 1993;Olsen et al, 1993;Tälleklint & Jaenson, 1993Gray et al, 1994;Ciceroni et al, 1996;Jaenson & Tälleklint, 1996;Craine et al, 1997;Gern et al, 1998;Kurtenbach et al, 1998aKurtenbach et al, , 1998bZeman & Januska, 1999;Zore et al, 1999;Gylfe et al, 2000). Small mammals, which often are reservoir-competent hosts, are mainly infested by larval ticks, to a lesser extent by nymphs, but rarely by adult ticks.…”

“…These latter mammals are reservoir-incompetent but are nevertheless important for pathogen transmission as they provide food for large numbers of adult females, thereby contributing to higher tick abundance (Jaenson & Tälleklint, 1999;Robertson et al, 2000). Studies have shown that in areas where game, such as roe deer and cattle, is present ticks are more abundant (Gray et al, 1992;Robertson et al, 2000) and the number of reported LB cases is higher (Zeman & Januska, 1999).…”

“…In the Czech Republic, the rates of TBEV-positive roe deer ranged from 14.1% to 47.6% (Hubálek et al 1993, Zeman andJanuška 1999). In other European countries, the TBEV positivity rates were in the range of 8.7-50%, suggesting that roe deer is an important link in the spread of TBEV (Borcić et al 1990, Skarphedinsson et al 2005, Rizzoli et al 2009, Kiffner et al 2011.…”

In the Czech Republic, the incidence of human tick-borne encephalitis (TBE) has been increasing over the last two decades. At the same time, populations of game have also shown an upward trend. In this country, the ungulate game is the main host group of hosts for Ixodes ricinus female ticks. This study examined the potential contribution of two most widespread game species (roe deer [Capreolus capreolus] and wild boar [Sus scrofa]) to the high incidence of TBE in the Czech Republic, using the annual numbers of culls as a proxy for the game population. This was an ecological study, with annual figures for geographical areas-municipalities with extended competence (MEC)-used as units of analysis. Between 2003 and 2011, a total of 6213 TBE cases were reported, and 1062,308 roe deer and 989,222 wild boars were culled; the culls of roe deer did not demonstrate a clear temporal trend, but wild boar culls almost doubled (from 77,269 to 143,378 per year). Statistical analyses revealed a positive association between TBE incidence rate and the relative number of culled wild boars. In multivariate analyses, a change in the numbers of culled wild boars between the 25th and 75th percentile was associated with TBE incidence rate ratio of 1.23 (95% confidence interval 1.07-1.41, p = 0.003). By contrast, the association of TBE with culled roe deer was not statistically significant ( p = 0.481). The results suggest that the size of the wild boar population may have contributed to the current high levels and the rising trend in incidence of TBE, whereas the regulated population of roe deer does not seem to be implicated in recent geographical or temporal variations in TBE in the Czech Republic.
