Limited Range of Genetic Variation in Echinococcus multilocularis

Limited range of genetic variation in Echinococcus multilocularis.

DNA sequencing of 1.3 kb of rDNA containing both internal transcribed spacers (ITS1, ITS2) and adjoining rRNA coding regions in each of 11 Echinococcus multilocularis isolates from Germany, Japan, and Alaska resulted in identical nucleotide sequences except for a single polymorphic locus 54 bp upstream of the 3' end of the 18S coding region, separating Eurasian isolates from an Alaskan isolate....

Echinococcus multilocularis in Estonia

To the Editor: Alveolar echinoco-ccosis (AE) caused by Echinococcus multilocularis is one of the most important emerging zoonosis in Europe. The fatality rate is >90% in untreated patients (1). In Europe, the distribution range of the zoonotic tapeworm E. multilocularis has expanded over the last few decades, and the parasite attracts increasing awareness as a public health issue (2–5). In 2003...

Echinococcus multilocularis in Dogs, Japan

To the Editor: In the October 2005 issue of Emerging Infectious Diseases, Song et al. described a fiber-optic, microsphere-based, highdensity array composed of 18 speciesspecific probe microsensors, used to identify biological warfare agents, including Clostridium botulinum (1). Although the researchers used multiple probes for C. botulinum, we doubt that this approach is suitable for this orga...

Echinococcus multilocularis in Northern Hungary

To the Editor: Echinococcus mul-tilocularis infection is one of the most dangerous zoonoses in the Northern Hemisphere and causes more human death than rabies in Europe. Recent data indicate that E. multilocularis infection is spreading geographically and is being transmitted at an increasing rate in Europe (Figure). Since 1995, the parasite has been found in Poland, the Czech Republic, the Slo...
