Gastro-intestinal helminths in chamois (Rupicapra rupicapra) in the Dolomites, Italy

From November to December 1994, 54 chamois hunted in a small area of the Dolomites were examined for gastro-intestinal parasites Prevalences and intensities of the species found are reported. The parasite burden decreased with age, no differences associated with sex were found. The parasite species with a prevalence > 2% fit a negative binomial distribution, but the degree of aggregation decreased progressively with age, so that in the younger class (6-12 months) most of the parasite species fit a poisson distribution.
