Prevalence of echinococcosis in pigs and sheep in the Slovak Republic.
The prevalence of echinococcosis in slaughtered animals has been monitored in the Slovak Republic between 1971 and 1990. In pigs, the prevalence dropped almost constantly from 3.85% to 0.13%, by as much as 15% per year. The dynamics of prevalence in sheep differs substantially from that in pigs. Significant 12 year, 6 year and 3 year periodicities predominate over a nonsignificant and slight decrease of prevalence by only 1% per year. Therefore, the prevalence fluctuates in the period of observations between 0.49 and 3.72%. No significant correlations or cross-correlations have been found between the prevalences in the two groups of animals.
