Wild life surveillance on Echinococcus multilocularis in Sweden
نویسندگان
چکیده
Background Echinococcus multilocularis is a tapeworm whose adult stages parasitize the intestine of canids such as foxes and wolves. Also domestic dogs and cats can act as definitive hosts. The sylvatic life cycle includes small rodents as intermediate hosts but humans may become accidentally infected by ingestion of eggs. Sweden, Finland, UK, Ireland, and Malta are considered to be free of this parasite and therefore have maintained their national rules as regards deworming of pets at movement into the countries. According to the EC regulation, these national rules can be applied during a transitional period to 2010. In order to confirm the absence of E. multilocularis in Sweden, monitoring of foxes is being carried out continuously. These investigations are financed by the Swedish government.

Present status, actions taken and future considerations due to the findings of E. multilocularis in two Scandinavian countries.
When Echinococcus (E.) multilocularis was first detected in mainland Scandinavia in Denmark in 2000, surveillance was initiated/intensified in Sweden, mainland Norway and Finland. After 10 years of surveillance these countries all fulfilled the requirements of freedom from E. multilocularis as defined by the EU, i.e. a prevalence in final hosts <1% with 95% confidence level. However, in 2011 E....

BACKGROUND The fox tapeworm Echinococcus multilocularis has foxes and other canids as definitive host and rodents as intermediate hosts. However, most mammals can be accidental intermediate hosts and the larval stage may cause serious disease in humans. The parasite has never been detected in Sweden, Finland and mainland Norway. All three countries require currently an anthelminthic treatment f...

The Danish surveillance programme for Echinococcus multilocularis was initiated in September 2011, and so far 679 wild carnivores have been examined. In April 2012, one infected fox was detected in Højer near the Danish-German border, and in January 2013 three additional foxes from the same area were found infected. Local prevalence in the area was 31% (four of 13 foxes) which is a new epidemio...

Over the last decade, studies have begun to shed light on the distribution and genetic characterization of Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), in North America. Recent findings indicate that the parasite is likely expanding its range in the central region of the United States and Canada and that invasions of European strains might have occurred. In ...
