Their average EH infection rate reached 19.4%. EH prevalence was outstandingly high in 1982-1983, when one-third of the sheep flocks were infected in Covasna County (Fig 2B). Of the regions studied, the region of Batanii Mari (27.0-89.6%)) and the regions of Bisericani and Estelnic [(Esztelnek), 13.7-27.5%)] showed a high prevalence of infection. Sheep kept in farmers' cooperatives had the highest prevalence (27.1%>), followed by sheep kept in flocks of state farms (18.7%>), and by those of private farmers (9.7 %>). Table 3 summarizes EH infestation of sheep by organ and type of the cyst. EH infection of swine: During the study it was found that EH infestation of swine was also considerable: 6.9% of 37,572 swine slaughtered annually were infected; in 1989 this rate reached 10.0% (Fig. 4). Considering each region separately, Ozun (33.3%) in 1990), Baraolt (10.7%) and Brates (10.6% in 1989) showed the highest prevalence of infection. Swine of private farmers, especially those of shepherds were most severely infected, their prevalence of infection reached 33.3% (Sikó Barabási and Bokor 1991, Sikó Barabási et al. 1991 ). As shown in Table 4, the prevalence of cysts was over 50%> in the liver. Of the intermediate hosts, wild boars showed the highest prevalence of infestation (22.0 % of the 635 wild boars shot on huntings), especially in the zones of Baraolt Fig. 3.
