METHODS Baseline data from a prospective cohort study of 204 persons with chronic HCV infection were used for analysis. The outcome was fibrosis score on biopsy,(More)
We use results from a simulation-based model of nematode infection of sheep to refine the parameters in a simpler generic model of host-parasite population dynamics. These parameters describe the following host-parasite traits: probability of establishment of ingested larvae, mortality rate of adult parasites, and fecundity of adult female parasites. This(More)
This paper presents an individual-based model for gastrointestinal nematode parasites of sheep and includes the effect of these parasites on the liveweight performance of young sheep. Parasitism is known to affect the host animal in at least two ways. The first induces a loss of appetite in the host, which reduces pasture consumption compared with the(More)
