Aim of the work- This research aims to study the epidemiology of the parasite in livestock by using statistical methods for analyzing the numbers of infections and prevalence of the disease among one year (1431HD) in the camels, cattle, sheep and goats..The genus Echinococcus is of great importance because it can cause the cystic echinococcosis( CE), or hydatid cyst, this disease is one of the serious parasitic diseases that may lead to death, and only can be treated surgically This disease can bring a lot of material loss to livestock and can cause serious ill health in man. The genus Echinococcus contains a number of zoonotic species.There are at least 4 species in the genus.   Material and methods : The data where collected regularly each week for among one year from the official slaughter house records for the infected camels, cattle, sheep and goats with the cystic echinococcosis, all the collected data were inserted in tables and divided to four quarters(Q1,Q2,Q3 and Q4) three months in each quarter, then statistical analysis (Chi test for goodness of fit and for independence) where used to analysis the numbers and prevalence of infected animals.   Results: The present study have been demonstrated that the prevalence of the CE in the year 1423HD was higher in camels with percentage of 7.21% followed by cattle (6.35%) then sheep (2.60%) and the least in goats (1.84%) for both local and imported livestock ,there were very high significant relation between the local and imported livestock and there were very high significant relation between types of animals and between the fourth quarter Q4 and the other quarters (Q1, 2,&3).   Conclusion: The results obtained in this study showed abundant rate of CE in slaughtered animals, and it proved the presence of  echinococcosis the deadly disease in the region of the study, which leads to think strongly to find  intensive controlling programs to eliminate or eradicate this disease to avoid losing livestock and reducing man mortalities or infections. More epidemiological studies are needed to watch the changes in the prevalence of the cystic echinococcosis because it is a major public health problem throughout the world and causes serious socio-economic effects
