period of survey extended from (April 2008 to March 2009) in different
localities including (El-basateen, Kafr dawoud and Menof abattoirs) by
examination of slaughtered animals for detecting of the occurrence and
Prevalence of hydatidosis among different animal species in addition,
morphological description of the recovered Hydatid cyst. Molecular
analysis of hydatid cyst recovered from different animal species was also
performed.
The Percentage of infection in Cattle, Buffaloes, Sheep and Camel
were 2.03%, 1.16%, 4.41% and 24.46% respectively. The most
commonly infected organs were the lung and the liver. Most of hydatid
cysts recovered from camel and sheep were fertile, while those recovered
from cattle and buffaloes were sterile.
Concerning to the seasonal occurrence of hydatidosis among
different animals the highest infection rate in cattle, buffaloes and sheep
was recorded during spring season while the highest infection rate in
camel recorded during autumn season. The peak of infection observed
during April in case of buffaloes and sheep while May and November in
case of cattle and camel respectively.
Concerning to the occurrence of hydatidosis in relation to the age of
examined animals, aged animals are most frequently infected.
The occurrence of hydatid cyst in relation to animal sex the
