'''Worm population dynamics - Continuous infection'''

It is important to remember that a worm burden inside an animal grazing at pasture does not remain static, but is continually changing i.e. as older adult worms are lost, more infective larvae are recruited. A state of equilibrium is reached i.e rate at which L3 establish = rate at which adult worms are lost. In an immune animal, the same equilibrium exists, except that fewer of the L3 ingested become established.
