| [prediction of sites with an increased risk of infestation with ixodes ricinus and tick-borne encephalitis infection in the central bohemia region based satellite data]. | based on elaboration of a prediction map of sites of increased incidence of ixodes ricinus associated with an increased risk of attack on humans and activation of the virus of tick-borne encephalitis it was assumed that different types of vegetation can serve this purpose as suitable indicators. for assessment of these sites and their location on the territory of the central bohemian region (on an area of 11,508 sq.km) data from spectral analysis of reflected light recorded by a scanner, themati ... | 1998 | 9511279 |
| borrelia-infection rates in tick and insect vectors accompanying human risk of acquiring lyme borreliosis in a highly endemic region in central europe. | the methods of spatial statistics were applied to assess the geographical pattern of risk of lyme borreliosis in central bohemia, the czech republic, based on retrospective data on disease contractions. the statistical risk was then compared at 15 selected localities with the infection challenge presented by ticks and insects carrying borreliae. over 5,000 ixodes ricinus (l.) ticks and 390 haematophagous dipterans were screened by direct immunofluorescence method, and the spatial and seasonal va ... | 1998 | 9868793 |
| tick-borne encephalitis and lyme borreliosis: comparison of habitat risk assessments using satellite data (an experience from the central bohemian region of the czech republic). | the vegetation types have been used as the indicators of an ecosystem suitable for high incidence of ixodes ricinus ticks and their hosts, for the circulation of tick-borne diseases pathogens and, accordingly, for the existence of natural foci of these infections, namely tick-borne encephalitis (tbe) and lyme borreliosis (lb). the method of remote sensing offers a suitable solution to this problem. we attempted to prepare the habitat risk assessment maps on the territory (11,500 km2) of central ... | 1999 | 10084020 |
| mosaic pattern of borrelia infection in a continuous population of the tick ixodes ricinus (acari: ixodidae). | an array of 12 20 x 20 m quadrats in a mixed forest near poteply, central bohemia, czech republic, was investigated for the abundance and spatial distribution of host-questing ixodes ricinus nymphs and their infection with borreliae. tick densities were estimated by flagging and their borrelia infection status was determined by direct immunofluorescence. while the tick population appeared to be continuous and homogeneous based on quadrat counts, their infection with borreliae evinced a mosaic pa ... | 1999 | 10399308 |
