| pubmed-article:3870641 | pubmed:abstractText | The distribution of gastrointestinal nematodes in different populations of wild ruminants has been studied with regard to density of the animals and the presence of domestic ruminants in the habitat. The degree of parasite overdispersion among the hosts has been examined in the hypothesis of a negative binomial model of distribution. The results show that the density has a greater weight than cohabitation with domestic ruminants, in destabilizing the host-parasite relationship. | lld:pubmed |
