BACKGROUND Alveolar echinococcosis (AE) is caused by the larval stage (metacestode) of Echinococcus multilocularis. The domestic dog can act as a definitive host and harbor adult cestodes in its small intestine or become an aberrant intermediate host carrying larval stages that may cause severe lesions in the liver, lungs and other organs with clinical signs similar to AE in humans. CASE PRES...

The aim of the investigation was to estimate the epizootic situation concerning infection by the cestode Echinococcus multilocularis Leuckart, 1863 in dogs (Canis lupus familiaris Linnaeus) from a Polish region where this parasite is highly prevalent in red foxes. Faecal samples (n = 148) were collected from rural dogs in Podkarpackie Province. Samples were examined through nested PCR (for E. m...

BACKGROUND Alveolar echinococcosis (AE) is a neglected zoonosis presenting with focal liver lesions (FLL) with a wide range of imaging patterns resembling benign as well as malignant FLLs. Complementary serology and histopathology may be misleading. OBJECTIVE The objective of our study is to highlight pitfalls leading to wrong diagnoses and harmful interventions in patients with AE. DESIGN ...

The early-phase migration dynamics of Echinococcus multilocularis in the intermediate hosts remain largely unknown. We compared parasite burden intestine, liver and faeces DBA/2 C57BL/6 mouse strains using parasite-specific quantitative PCR. Our results indicated that parasites invaded mainly from middle segments small intestine completed to within 24 h p.i. mice had lower DNA burdens but highe...

The comparative development of Echinococcus multilocularis was studied in its definitive hosts, the fox, dog, cat and raccoon dog, beyond the pre-patent period to 90 days post-infection. All host species, apart from cats were susceptible to infection and capable of supporting substantial worm burdens. Although worms in cats matured and produced thick-shelled eggs, their overall development was ...

The aim of this study was to obtain uniformity in strobilar development of Echinococcus multilocularis from protoscoleces in vitro. The isolate of E. multilocularis used was derived initially from a human case in France and subsequently maintained in the laboratory by intraperitoneal passage in Meriones unguiculatus. Protoscoleces used for culture were obtained using preparative procedures in w...

Echinococcus multilocularis, a vulpine intestinal tapeworm, is the causative agent of alveolar echinococosis in humans, one of the most severe and lethal parasitic infections in man. To date, there is very little knowledge about the genetical polymorphism of this parasite. To assess sequence polymorphism, we analysed a sample of 33 E. multilocularis isolates from Europe, North America and Asia ...

Antibodies against Echinococcus multilocularis metacestodes were screened by immunoblotting sera from patients with alveolar echinococcosis (n = 39), cystic echinococcosis (n = 109), or other parasitic infections (n = 66) and healthy individuals (n = 32). Two antigens, approximately 70 and 90 kDa, are found to be valuable for confirmatory diagnosis, with a sensitivity and specificity of 100 and...

 Alveolar hydatid disease is a highly malignant form of echinococcosis caused by the larvae of the cestode echinococcus multilocularis. Alveolar hydatid disease always affects the liver and can metastasise to the lung and brain. Early diagnosis and precise evaluation of the localization as well as the extent of lesions are essential for treatment. In this report, we present ultrasound and compu...
