Several efforts to establish an in vitro model of E. granulosus have been undertaken; however, many of them have been designed for Echinococcus multilocularis. Echinococcus alveolaris/multilocularis. The metacestodes of Echinococcus multilocularis and Echinococcus granulosus are the causative agents of alveolar and cystic echinococcosis (AE, CE), respectively. Humans are accidental hosts, and the infection occurs by ingesting food contaminated with Echinococcus eggs 3. Here, we compared miRNA profiles of the peritoneal macrophages of E. multilocularis-infected and un-infected female BALB/c mice using high-throughput sequencing. Echinococcus, particularly among wildlife. The taeniid tapeworm Echinococcus granulosus is the causative agent of echinococcal disease, a major zoonosis with worldwide distribution. Introduction. Echinococcus larvae develop differently in the intermediate host, resulting in diseases with different clinical courses. Echinococcus multilocularis distribution New AE cases per year: Europe: 100-200 Russia: 1100 China: 17 000 (91%) Torgerson et al., 2010 Number of alveoloar echinococcosis cases reported in Kyrgyzstan, by patient sex, 1995–2011. 34 Keywords: mebendazole, RNAi, tubulin, flame cell, Echinococcus 35 multilocularis 36 INTRODUCTION 37 The larval stage of the fox tape worm, Echinococcus multilocularis, 38 is the causative agent of alveolar echinococcosis (AE), which is 39 considered to be the most lethal human helminthiasis (1).
