WORM CONTROL AND ANTHELMINTIC RESISTANCE - ADVENTURES WITH A MODEL

There are three common questions asked of parasitologists about anthel mintic resistance. Does it matter? How do you prevent it? Can you help me (it's here!)? In short, the respective answers are yes, read on an d read on. Elizabeth Barnes, Robert Dobson and Ian Barger examine thes e issues in the context of nematode parasite control in grazing sheep. With the aid of a model, they examine some important factors that inf luence drug resistance and how farm management decisions and worm gene tics modify these factors. They also explore the likely impact of new technologies on drug resistance and hour efficient they need to be to sustain good worm control.
