| detection of space-time clusters and epidemiological examinations of scabies in chamois. | in this paper some methodological approaches towards the detection of temporal, spatial and space-time clusters are presented and discussed in context with epidemiological factors of scabies in chamois. this presentation comprises in particular the use of the scan test (wallenstein, 1980) for the detection of temporal clusters and the tests developed by knox (1964) and mantel (1967) for the testing of spatiotemporal interactions. between 1952 and 1998 a total of 1689 cases of scabies in chamois ... | 2000 | 10936546 |
| use of variograms to detect critical spatial distances for the knox's test. | we aimed to find critical spatial distances (as an input quantity for the knox's test) using geostatistical methods. the spatiotemporal data set included all individual-chamois cases of scabies observed in styrian chamois populations in 137 of 2837 game preserves in styria (a province in the south of austria) over the time period between 1952 and 1998. theoretical variogram models were fitted to empirical variograms, which were calculated for cycles of 5 years. the unit of analysis was the mean ... | 2002 | 12062518 |
| [mycobacterium avium subsp. paratuberculosis in wild animal species and cattle in styria/austria]. | infections with mycobacterium ovium ssp. paratuberculosis (m. paratuberculosis) are increasingly recognised worldwide. in addition to an increased prevalence of paratuberculosis in austrian cattle herds, recent years have also shown a rise in infections with m. paratuberculosis in wild red and roe deer, chamois and mouflon. during the period from june 2002 to september 2004, mesenteric lymph nodes were taken from a total of 483 wild animals hunted or found dead and from 338 deceased cattle. samp ... | 2005 | 16048043 |
