Abstract
Hydatid disease is a re-emerging disease that infec ts human and animals world-wide. Cystic Echinococcosis (CE) is the most common form of the disease. In Egypt, CE is an endemic disease and several reports have in dicated an increasing prevalence rate of the CE infection in a nimals and humans in the last few years. The aim of the current study is to determine the prevalence rate and other epidemiological factors in the infecting of rumina nts with CE in different locations in Upper Egypt. The data gat hered shows that of 4,498 animals examined, 89 (1.97%) had the hydatid cyst. Sheep were the most affected animal species (14.1%), then goats (13%), camels (5%) a nd cattle (0.068%), while buffaloes were free from infection. A higher percentage were affected in the liver (39 .3%) than in the lungs (32.5%) and other viscera (2.2%), whil e 25.8% were affected in both the liver and the lun gs The general fertility rate of cysts examined was 27.71% ; cysts of camel origin were the most fertile (66.6 %), followed by those of goats (29.41%) and sheep (15.51%); that of cattle was 0%. The current study provides curre nt data about the status of CE infection in ruminants in Up per Egypt that will aid further studies and enable more precise planning for effective control strategies.

Cystic Echinococcosis (CE) is re-emerging as a major public health issue (Torgerson and Budke, 2003)
The current study provides current data about the status of CE infection in ruminants in Upper Egypt that will aid further studies and enable more precise planning for effective control strategies
As regards the variation among the animal species, CE infection was detected to be more prevalent in sheep (14.1%) and goats (13%) than in camels (5%) and in cattle (0.068%), while buffaloes were free from such infection (Table 1)
Summary
CE is re-emerging as a major public health issue (Torgerson and Budke, 2003). Cystic Echinococcosis last 5 years) and treated in the hospitals of Cairo and the (CE) is the most common form, caused by the larval stage of E. granulosus. It is seen in most regions of the world- the Mediterranean region, Africa and the Middle East-and it is the most frequently encountered form of hydatidosis in humans (FAO, 1982; Thompson, 1995; Torgerson and Budke, 2003; Haridy et al, 2006)
