The Prevalence and History of Echinococcus granulosus Infection in Dogs in Libya and the Potential Role of Dogs in Transmission of Cystic Echinococcosis

September 23, 2020 AGRICULTURE 0

Libya is a country situated in North Africa, south to the Mediterranean with an area of 1 759 540 kmĀ²,
and border line of 4348 km, this makes the country fourth largest in Africa and the seventeenth largest
in the world. Sheep, goats, cattle and camels are the most numerous grazing animals in Libya, and
are important intermediate hosts for Echinococcus granulosus which is the causative parasite of cystic hydatid disease condition. E. Granulosus is a tiny tapeworm that parasitizes the small intestine of canids, mainly dogs, which act as definitive hosts for the parasite. Infected dogs are the main source of infection to humans and livestock. The parasite is widely distributed in many parts of the world and is very common in North African countries. In Libya, the rate of infection with echinococcosis in dogs was reported to be lower than 7% to 80% in stray dogs, 34.8% to 60% in sheep/guard dogs and 7.7% to 21.6% in farm/house dogs. This data fulfills the WHO criteria and suggests that the incidence of infection with echinococcosis/ hydatidosis in some parts of the country can be reaching the level of hyper endemic. Diagnosis of echinococcosis in infected dogs can be performed by isolating the parasite from their faeces or from the contents of their small intestine after necropsy. Recent developments in immunodiagnostic assays for echinococcosis in dogs have been described. Public health and risk factors as well as ways of hydatid disease treatment and various control strategies, including the use of veterinary vaccines, have also been discussed.
