Maximum values obtained from measurements vary in liver flukes from the three host species (table 2).
Human infections with the lung fluke are acquired by eating raw or undercooked freshwater crabs containing live metacercariae.
This temperature has also been used for storing metacercariae by other authors, thus enabling comparative analysis with lowland liver fluke isolates.
We then focus on flukes and snails, highlighting important biological traits with regard to population structure.
Naturally infected flukes were identical with those recovered from experimentally infected fish.
In the second group of six rabbits each given 200 metacercariae, five were infected, with two or three flukes per host.
When metacercariae harvested from the snakes and intercostal muscles of rodents were infected orally to cats, they developed into adult flukes in the small intestine.
Muscle fibres enzymatically isolated from the fluke have been characterised in terms of their morphology and contractile proteins.
