Abstract
During a survey of 14 Libyan abattoirs in 1985–1987 the carcasses of 4316 locally-bred goats, cattle and camels were inspected for cysts of Echinococcus granulosus.
Of 2295 goats, 35 adults (1·5%) had cysts; no kids were infected. Thirty-one adult goats had infected livers, 28 had lung infections, and four each had cysts in their kidneys and spleens. Most (59·7%) of the infections were light, with medium infections in 31·3% and heavy infections in 8·9%; 85·7% of the cysts in the lungs and 38·7% of those in the livers were fertile; three of the four kidney infections and two of the four spleen infections were fertile.
Of the 1023 cattle carcasses, mild infections with E. granulosus were seen in 55 (5·4%); all the cysts were sterile and confined to the liver.
Of998 camels, 358 (35·9%) had hydatid cysts. These involved the lungs in 96·9%, either as the sole site (74·3%) or jointly with the liver (22·6%). Lung cysts (57·6%) and liver cysts (41·2%) were fertile.
