1.   The disease can be very serious in adult animals.

2.   This is hardly surprising, bearing in mind that no other adult animal naturally drinks milk.

3.   The adult animals reach a maximum length of two meters.

4.   Because only the V chain is required for recognition, virtually all T cells expressing the appropriate V chains are activated by superantigens, regardless of their V.

5.   When exogenous superantigens are injected into adult animals, T cells expressing the appropriate Vs initially proliferate and then, paradoxically, become anergic and die.

6.   But by comparing the bodies of two adult animals that are known to differ according to a single gene, they can see what effects that single gene has.

7.   Although the basic epidemiology in beef herds is similar to diary herds, the influence of immune adult animals grazing alongside susceptible calves has to be considered.

8.   This level is probably sufficient to cause clinical disease in susceptible adult animals or to upset the normal functioning of the gastric mucosa in immune cows.

9.   The highest prevalences have been recorded in dogs of less than six months of age, with the fewest worms in adult animals.

10.   Adult animals were fitted with collars holding radio transmitters so their migrations can be tracked.
