Host-parasite checklist of nematodes of domestic ruminants in New Zealand

Abstract

Extract

Nematodes of domestic ruminants are abundant and widespread throughout New Zealand, and, although the economic importance of some of them is well-recognized, the literature regarding the occurrence, incidence, and distribution of individual species is sparse and very incomplete. A partial explanation of this may be that in diagnostic laboratories in this country, as elsewhere, it is usual for the purposes of routine diagnostic worm counts to identify the parasites at the generic level only. Thus, little information is gained regarding the geographical and seasonal distribution of individual species where more than one species of a genus may occur in the same location in any particular host.
