investigations on a swiss area highly endemic for echinococcus multilocularis.anecdotal information suggested that a focus of hyperendemicity may be present in a small area of the canton of fribourg in switzerland. therefore, the prevalence of e. multilocularis was assessed both in the fox and the rodent population over a two-season-period. a high prevalence ranging between 47% and 56% was consistently determined in the fox population. an arvicola terrestris population was infected at 39% in the first season of investigation and at 11% in the following season. a subsequen ...19968688861
