Epidemiological aspects of cystic echinococcosis in slaughtered herbivores in Sari abattoir, North of Iran

Abstract

A study was conducted to assess the ruminants' hydatidosis in Mazandaran Province, Northern Iran. A total, 1,799 sheep, 985 goats and 362 cattle slaughtered at Sari industrial slaughter house were examined for hydatid cyst infection. The results indicated that 65.2% of sheep, 37.8% of goats and 40.1% of cattle were infected. The liver and lung infection rate in sheep were 18.8 and 4.3%, goats 17.2 and 12.6% and cattle 44.1 and 7.6%, respectively. The study showed that 766 (45.3%) out of 1,691 infected animals had moderate degree of infection. Geographical zone survey indicated that 1,381 (89.2%) out of 1,546 sheep and goats infected with hydatid cyst were non-indigenous and originated from north-eastern provinces of Iran. On the contrary, 50.3% of infected cattle originated from Mazandaran Province (indigenous).

Serological evidence of human cystic echinococcosis and associated risk factors among general population in Mazandaran Province, northern Iran

“…In appropriate human practices and behavior and closely communication to dogs may remain as a main danger to public health [31] , [32] . On the other hand, a recent study in slaughtered herbivores in Mazandaran demonstrated the situation of CE infection in livestock as followed 65.2%, 37.8% and 40.1% in sheep, goats and cattle; respectively [33] . These data confirms the high infection rate of CE among domestic animals in the area.…”

Environmental, climatic and host population risk factors of human cystic echinococcosis in southwest of Iran

“…Although the number of sheep and goats is higher than cattle in the studied areas, the CE prevalence rates in Fars are highest in cattle (11%), sheep (just under 5%) and goats (4.5%) [ 31 ]. Also, another study in northern Iran (Mazandaran province), showed that 40.1% of cattle and 37.8% of goats were infected by CE [ 32 ].…”

Global Distribution of Alveolar and Cystic Echinococcosis

“…Several surveys in Iran have indicated CE prevalence in livestock ranging from 1.3 to 74.4% in sheep, 0.4e37.8% in goats, 1.3e40.1% in cattle, 4.3e31.9% in buffalo, 8.8e35.5% in camels and 2% in donkeys (Ahmadi, 2005;Ahmadi and Meshkehkar, 2011;Eslami et al, 2014;Samavatian et al, 2009). In the northern Caspian coastal provinces, prevalence of CE ranged between 14.6 and 65.2% in sheep, 10.1e37.8% in goats and 12e41% in cattle (Mansoorlakooraj et al, 2011;Ziaei et al, 2011). In northwestern areas of the country, prevalence of CE ranged between 22.2 and 74.4% in sheep, 20e25% in goats and 28.3e38.3% in cattle Mirzaei et al, 2015).…”
