title: The pervalence of caecal threadworms (Trichostrongylus tenuis) in red grouse (Lagopus lagopus scoticus).
abstract: Ninety percent of wild red grouse examined carried threadworms in their intenstinal caeca. Old birds had 30 times as many worms as young birds. Some infections were as high as 30,000 worms. The occurrence of worms in old grouse conformed to the negative binomial distribution.
