The current prevalence and diversity of cystic echinococcosis in slaughtered animals in Egypt

AbstractCystic echinococcosis is a potential zoonotic helminthic disease affect a broad spectrum of mammals including humans worldwide. The economic impact of the disease interestingly requires updated gathering information on the prevalence in slaughtered animals. Accordingly, in the current study, 573 camels, 4300 sheep, and 1235 pigs were surveyed in four Egyptian municipal abattoirs. Among those, 62 (10.82%) camels, 33 (0.77%) sheep and 3 (0.24%) pigs had cystic echinococcosis in lungs, livers and spleen. The diversity of cysts revealed that positive-cystic echinococcosis animals from all species were detected in El-Basatin abattoir. In El-Monieb abattoir, sheep only were infected. In El-Waraa and Beni-Suef abattoirs, cysts were seen in camels only. Infected animals included both sexes. In camels, lungs were the most affected organs, while in sheep, livers were the most abundant. In pigs, hydatid cysts were detected only in lungs. Moreover, camel cysts were mostly large-sized (diameter  >  10 cm) with smaller cysts are also recorded. In sheep, small-, moderately- and large-sized cysts were equally present. Cysts in pigs were large-sized. Camels showed a higher percentage of fertile cysts (46.77%; 29/62) followed by sheep (21.21%; 7/33). Calcified/degenerated cysts were less in cam els (38.71%; 24/62) than in sheep (75.76%). Non-viable cysts were the less frequent in both species (14.52% in camels and 3.03% in sheep). All cysts recovered from pigs were fertile. In ...
