Comparative development of Echinococcus multilocularis in its definitive hosts [PDF]

open access: yesParasitology, 2006
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.

MORPHOLOGY OF THE LARVAL STAGES OF Elaeophora schneideri IN THE INTERMEDIATE AND DEFINITIVE HOSTS WITH SOME OBSERVATIONS ON THEIR PATHOGENESIS IN ABNORMAL DEFINITIVE HOSTS [PDF]

open access: yesJournal of Wildlife Diseases, 1974
Morphology of the larval stages of Elaeophora schneideri from the horse fly and the normal definitive host (Odocoileus hemionus) are described. Development of larvae in the horsefly begins in the fat bodies, but larvae enter the haemocoele early in the first-stage of development and remain in the haemocoele until they are third-stage (infective) and ...
