The influence of secondary Echinococcus multilocularis infection on reproduction and cellular immune response of mice was studied in BALB/c mice infected with 2000 E. multilocularis protoscoleces. Of the total infected mothers, 11.7% did not give birth and 10% of uninfected ones did not deliver. Both, healthy and infected mothers, produced on average 6-7 offspring per litter. The changes in production of seral IFN-gamma, TNF and IL-10 did not significantly influence the course of gravidity. On the other hand, more intensive metacestode growth was observed after the delivery. This study confirmed the ability of host organism to adapt to severe damage caused by E. multilocularis, not only in normal conditions, but also during pregnancy.

Alveolar echinococcosis (AE) is an infrequent zoonosis caused by Echinococcus multilocularis with a high degree of disability and mortality. Metastatic cerebral alveolar echinococcosis (CAE) is very rare and the lesions could lead to severe perilesional brain edema (PLBE) and subsequent uncontrollable intracranial hypertension. In this study, we sought to determine the expression of edema-associated factors in CAE lesions and their associations with PLBE.

Alveolar echinococcosis (AE) is a severe zoonotic disease caused by the metacestode stage of the fox tapeworm Echinococcus multilocularis. We recently showed that E. multilocularis metacestode vesicles scavenge large amounts of L-threonine from the culture medium.

Echinococcus larval stage or a hydatid cyst, a parasitic disease that passes from animals to humans. Echinococcus granulosus and, less commonly, Echinococcus multilocularis species cause the disease. Intracranial echinococcosis is rare, with an incidence of approximately 1%-2%.

Eurasian wolves () and domestic dogs () are definitive hosts of numerous cestode species. While infections with adult stages in canids are usually subclinical, some species pose a zoonotic risk or cause infections in wildlife and livestock, resulting in disease and/or economic losses. This study aimed to determine the prevalence, species composition, and geographical distribution of cestode infections in dogs and free-ranging wolves in Switzerland.

Cystic and alveolar echinococcosis are severe zoonotic diseases characterized by long asymptomatic periods lasting months or years. Viable Echinococcus spp. eggs released into the environment through the feces of canids can infect humans through accidental ingestion via hand-to-mouth contact or consumption of contaminated food or water.
