“…17,21,22 High human AE prevalence rates have also been reported in the areas that exhibited a high ratio of permanent grassland. 5 This study goes a step further, providing more evidence in favor of rodent populations of A. terrestris as a risk factor for human AE, while distinguishing its effects from those of climate, altitude, land usage, vegetation, and spatial autocorrelation. In this respect, the first plateau has captured the effects of all climatic and land composition variables introduced into the multivariate analysis.…”

Abstract. Concern is growing in Europe about alveolar echinococcosis (AE) with the increase in grassland rodent and red fox populations, intermediate and definitive hosts for Echinococcus multilocularis, respectively. The objective of this study was to assess the influence of rodent densities on human AE distribution. Spatial Poisson regression analyses were performed with geomorphologic features, landscape composition, climatic characteristics, and water vole density as independent variables. The outcome consisted of AE cases diagnosed over the period 1980-1992. High vole density yielded a 10-fold risk (relative risk [RR ] ϭ 10.34, 95% confidence interval [CI] ϭ 2.78-38.39), and the first plateau (400-700 m altitude) compared with the plain (200-400 m) was associated with a large increase in risk (RR ϭ 7.10, 95% CI ϭ 1.30-38.63). These results confirm that human AE is strongly influenced by the densities of arvicolid species. Foxes feeding almost exclusively on grassland rodents when the latter expand could mediate this relation.

“…Frequent outbreaks occur where the ratio of permanent grassland exceeds a certain value (50 % or 85 % of farmland for M. arvalis and A. terrestris, respectively) (Delattre et al 1992 ;Giraudoux et al 1997). In such systems foxes (Vulpes vulpes) become specialists and feed almost exclusively on grassland rodents, their diet getting more diversified only during the population crashes of grassland rodents (Weber & Aubry, 1993 ;Giraudoux et al 2002).…”

An area close to the Qinghai-Tibet plateau region and subject to intensive deforestation contains a large focus of human alveolar echinococcosis while sporadic human cases occur in the Doubs region of eastern France. The current review analyses and compares epidemiological and ecological results obtained in both regions. Analysis of rodent species assemblages within quantified rural landscapes in central China and eastern France shows a significant association between host species for the pathogenic helminth Echinococcus multilocularis, with prevalences of human alveolar echinococcosis and with land area under shrubland or grassland. This suggests that at the regional scale landscape can affect human disease distribution through interaction with small mammal communities and their population dynamics. Lidicker's ROMPA hypothesis helps to explain this association and provides a novel explanation of how landscape changes may result in increased risk of a rodent-borne zoonotic disease.

“…At a high ROMPA, production of young cannot be compensated by unsuccessful dispersion and rodent density reaches a very high level. [3][4][5][6] Landscape composition would therefore drive both the population dynamics of arvicolid species and the host-parasite interaction (foxes feed almost exclusively on grassland arvicolid species, with their diet becoming more diversified only during decreases in rodent populations). 7,8 The prevalence rates of E. multilocularis in foxes are remarkably high (20-70%) in endemic areas.…”
