Abstract

The viability rate of hydatid cysts was investigated in animals slaughtered in the abattoir of Thessaloniki, Macedonia, Greece. Two hundred sheep (100% infection rate), 106 cattle (56.6% infected), 203 pigs (9.3%) and 52 goats (15.4%) were examined. All fertile cysts contained viable protoscoleces. In sheep there was a mean of 1.1 (29.8% of total cysts) fertile cysts per animal containing 297.3 (81.3%) viable protoscoleces. The percentage of viable protoscoleces in the lungs was 82.3% and in the liver 71.2%. In cattle there was a mean of 0.1 (6.6% of total) fertile cysts per animal containing 46.4 (72.2%) viable protoscoleces. The percentage of viable protoscoleces in the lungs was 69.5 and in the liver 87. In swine there was a mean of 0.02 (9.5% of total) fertile cysts per animal containing 32.0 (76.8%) viable protoscoleces. The percentage of viable protoscoleces in the lungs was 97.1 and in the liver 68.9. In goats there was a mean of 0.1 (12.5% of total) fertile cysts per animal containing 12 (54.6%) viable protoscoleces. The percentage of viable protoscoleces in the lungs was 54.4% but no fertile cysts were found in the liver.
