Synergistic Effects of Anti-echinococcosis Drug Candidates Combined With Atovaquone in Culture Assays and Mice With Primary Infections of Echinococcus multilocularis.

Background Alveolar echinococcosis (AE) is a fatal zoonotic disease distributed mainly in the Northern Hemisphere. At present, its curative treatment relies on surgery, and the development of effective drugs is needed. We previously demonstrated the anti-echinococcal effect of atovaquone (ATV) as a mitochondrial complex III inhibitor in both in vitro and in vivo experiments.

Narrowing the region of candidate genes that control the development of protoscoleces of Echinococcus multilocularis in the mouse liver.

Alveolar echinococcosis is a zoonosis caused by the larval stage of Echinococcus multilocularis. In previous studies, QTL analysis using C57BL/6 N (B6) and DBA/2 (D2) which differ in susceptibility suggested the presence of genes on chromosome 1 that control protoscolex development. In this study, we constructed several congenic mice with different chromosome 1 regions substituted to confirm the presence of responsible genes and to narrow down the regions where the responsible genes exist.

Case report: infection in a dog showing gastrointestinal signs in Hokkaido, Japan.

is a cestode that causes human alveolar echinococcosis, a lethal zoonotic disease distributed in the northern hemisphere. The life cycle of this parasite is maintained in nature by voles as intermediate hosts and foxes as definitive hosts in Hokkaido, Japan. Although dogs are also susceptible to the parasite, the infection has been considered typically asymptomatic.

The first record of Brachylaima ezohelicis (Trematoda: Brachylaimidae) in the red fox (Vulpes vulpes schrencki).

Brachylaima spp. are trematodes that have a unique life cycle as they exclusively use land snails as the intermediate host. Although their intermediate host has been well studied, very little information is available about their definitive host, partly as isolation of its adult stage from wild animals is rare.

Mitogenomic exploration supports the historical hypothesis of anthropogenic diffusion of a zoonotic parasite .

Animal movement across regions owing to human activity can lead to the introduction of pathogens, resulting in disease epidemics with medical and socioeconomic significance. Here, we validated the hypothesis that human activity, such as the transportation of infected animals, has played a significant role in introducing the zoonotic parasite into Hokkaido, Japan, by synthesizing and evaluating parasite genetic data in light of historical records. Our analysis indicates that a major genetic group in Hokkaido originated from St.
