Abstract : Hydatidosis is one of the most parasitic disease transmitted from carnivores animals e.g. dogs to human ,causing deterioration in health and also transmitted to herbivores animals causing substantial economic loss in the productivity of meat with low quality . With increasing acquisition of dogs at home nowadays , with its high risk of infection with many parasitic diseases such as hydatidosis , the present study was conducted to provide a recent view on the current status of hydatidosis among slaughter animals in Jeddah through periodic visiting North Jeddah abattoir for one year . Obtained data about the infection were analysed statistically . Parasitological and histopathological examinations were done on some randomely selected liver and lung infected with hydatid cysts. The results revealed satatistically significant differences in infection rate of inbred and imported slaughter animals. Sheep and goats are the most infected animals . Seasonal variation had a statistical significant difference on infection rate. The total infection rate were(1.36%,0.42%) in inbred and imported animals respectively Liver and lung are the most infected organs . Seasonal variation had a statistical significant difference on infection rate . Parasitological results revealed that the intensity of infection of liver is more than the lung , small size cysts cysts were more in the liver while the large –sized ones were in the lung . The fertility & viability of cysts were more in the liver of sheep and goat than in the lung. The virulence of protoscolices from fertile hydatid cysts obtained from sheep, was higher than that obtained from camels. Histopathological results revealed necrosis, fibrosis, cloudy swelling and fatty degeneration of hepatocytes . The lung tissue showed fibrosis , atelactasis and emphysema. In conclusion the low infectivity rate of slauphtered animals with hydatid cyst revealed high heath awareness among people and the strict laws from Jeddah Province . Studies on strain variability must be done as it has an important rote in putting new programs for prevention and control of the disease . Periodic epidemiological study hydatidosis must be done also for noting the extent of its spread..
