Heritable variation in resistance to gastro-intestinal nematodes in an unmanaged mammal population.
The impact of parasites on natural populations has received considerable attention from evolutionary biologists in recent years. Central to a number of theoretical developments during this period is the assumption of additive genetic variation in resistance to parasites. However, very few studies have estimated the heritability of parasite resistance under field conditions, and those that have ...
متن کاملAn anthelmintic test for gastro-intestinal nematodes of cattle.
REINECKE, R. K. An anthelmintic test for gastro-intestinal nematodes of cattle. Onderstepoort]. vet. Res. 39(3), 153-178 (1972). Suitable experimental groups of calves for controlled anthelmintic tests were created by repeatedly dosing susceptible worm-free animals orally with infective larvae of Haemonchus placei, Osterta,~ia ostertagi, Oesophagostomum radiatttm and Cooperia spp. (C. pectinata...
متن کاملStrategies for vaccination against gastro-intestinal nematodes.
A great diversity of gastro-intestinal nematodes parasitise man and his animals. Each nematode is antigenically highly complex with distinct developmental stages. The parasites occupy a range of niches in the host gut and have a variety of feeding habits. Hosts have evolved only partially successful local immune responses. The host and parasite factors modulating these responses are described. ...

متن کاملAdministration of Duddingtonia flagrans chlamydospores to goats to control gastro-intestinal nematodes: dose trials.
The ability of the nematophagous fungus Duddingtonia flagrans to reduce the number of infective nematode larvae in coproculture was investigated in goats using different doses of chlamydospores (0, 1.25 x 10(5), 2.5 x 10(5), 5 x 10(5) chlamydospores/kg BW/day) given by oral administration or by voluntary consumption in feed during natural or experimental infections with nematodes. The kinetics ...
