Abstract
Of 10,362 cattle examined in Bangladesh, 4,368 (42·15%) harboured hydatid cysts. One to three-year-old cattle had the lowest (11·34%) and those over nine years old the highest (93·21%) infections. Organ involvement was as follows: liver 35·18%, lungs 32·02%, spleen 0·80%, heart 0·41%, kidney 0·25%, omentum 0·11% and both liver and lungs 31·20%. Fertile cysts occurred in 8·11%, sterile in 74·91%, calcified in 9·43%, suppurative in 6·04% and undeveloped in 1·51% of animals.
