| age, season and spatio-temporal factors affecting the prevalence of echinococcus multilocularis and taenia taeniaeformis in arvicola terrestris. | taenia taeniaeformis and the related zoonotic cestode echinococcus multilocularis both infect the water vole arvicola terrestris. we investigated the effect of age, spatio-temporal and season-related factors on the prevalence of these parasites in their shared intermediate host. the absolute age of the voles was calculated based on their eye lens weights, and we included the mean day temperature and mean precipitation experienced by each individual as independent factors. | 2011 | 21247427 |
| spatial and temporal aspects of urban transmission of echinococcus multilocularis. | high prevalences of echinococcus multilocularis have been reported from foxes of the city of zurich, switzerland. in order to characterize transmission in urban areas, a coproantigen elisa was evaluated for diagnosing the infection in fox faecal samples collected in the environment. in addition, trapped rodents were investigated for the presence of metacestodes. faecal samples could reliably be classified as being of fox origin by assessing physical properties as shown by the different parasite ... | 2002 | 12118719 |
| veterinary aspects of alveolar echinococcosis--a zoonosis of public health significance. | human alveolar echinococcosis (ae), caused by the metacestode stage of echinococcus multilocularis, is a serious zoonosis which caused up to 100% lethality in untreated patients before the 1970s, when modern methods of treatment were not yet established. ae occurs in large areas of the northern hemisphere mostly with low country-wide prevalences, but high prevalences of up to 4% have been reported from small population groups in highly endemic foci, e.g. from china. ae includes many veterinary a ... | 2001 | 11516580 |
| high prevalence of echinococcus multilocularis in urban red foxes (vulpes vulpes) and voles (arvicola terrestris) in the city of zürich, switzerland. | over a period of 26 months from january 1996 to february 1998, 388 foxes from the city of zürich, switzerland, were examined for intestinal infections with echinococcus multilocularis and other helminths. the prevalence of e. multilocularis in foxes sampled during winter increased significantly from 47% in the urban to 67% in the adjacent recreational area, whereas prevalence rates of other helminths were similar in both areas. seasonal differences in the prevalence of e. multilocularis were onl ... | 2000 | 10726275 |
| parasitological and serological studies on the prevalence of echinococcus multilocularis leuckart, 1863 in red foxes (vulpes vulpes linnaeus, 1758) in switzerland. | in the canton of zurich in switzerland, 1,252 red foxes (vulpes vulpes) were examined during 1990-1991 for intestinal stages of echinococcus multilocularis using the mucosal smear technique. special safety precautions were employed during examination. an average of 35% (432 foxes) were infected, mostly with low to medium numbers of gravid worms producing thick-shelled eggs. in the eleven districts of the canton, prevalence rates varied between 13% and 57%. an average of 29% of the foxes had anti ... | 1992 | 1305853 |
| [dog and fox faecal contamination of farmland]. | the contamination with faeces from dogs and foxes was documented on 14 different grassland areas in the canton of zurich, switzerland, over one year. a total of 402 dog and 58 fox faecal samples were collected from the grasslands, further 236 faecal samples were retrieved from robidog® units (disposal units for dog waste bags) in the immediate vicinity. the degree of fecal contamination per 100 m2 and year was 0.07-0.75 for dog samples and 0-0.06 for fox samples. dog faeces from robidog® units a ... | 2015 | 26753365 |
| mathematical modelling of echinococcus multilocularis abundance in foxes in zurich, switzerland. | in europe, the red fox (vulpes vulpes) is the main definitive host of echinococcus multilocularis, the aetiological agent of a severe disease in humans called alveolar echinococcosis. the distribution of this zoonotic parasite among the fox population is remarkably aggregated with few heavily infected animals harbouring much of the parasite burdens and being responsible for most of the environmental parasitic egg contamination. important research questions explored were: (i) spatial differences ... | 2017 | 28077161 |
| dynamics of the force of infection: insights from echinococcus multilocularis infection in foxes. | characterizing the force of infection (foi) is an essential part of planning cost effective control strategies for zoonotic diseases. echinococcus multilocularis is the causative agent of alveolar echinococcosis in humans, a serious disease with a high fatality rate and an increasing global spread. red foxes are high prevalence hosts of e. multilocularis. through a mathematical modelling approach, using field data collected from in and around the city of zurich, switzerland, we find compelling e ... | 2014 | 24651596 |
