| observations on the epidemiology of autumn nematodirosis in weaned lambs in a scottish sheep flock. | nematodirosis was diagnosed in the south-east of scotland during two consecutive autumns in lambs which were grazed on the same field. the problem was unpredicted based on the knowledge of the pasture and animal management, and rudimentary understanding of the behaviour of free-living stages of nematodirus battus in the region. unlike the epidemiology that has been described in the south of england, whereby autumn infection of lambs is believed to arise from autumn hatching of eggs shed during t ... | 2012 | 22266686 |
| variation in the hatching behaviour of nematodirus battus: polymorphic bet hedging? | previous work on the transmission dynamics of nematodirus battus, an important nematode parasite of farmed ruminants in temperate regions, suggests that it operates a bet-hedging strategy. hatching of cold-sensitised eggs is concentrated in spring, while alternative hatching of non-cold-sensitised eggs in autumn mitigates the risk of poor conditions for hatching in spring or host absence during peak larval availability. isolates from scotland showed much less propensity to hatch without chilling ... | 2010 | 19944106 |
