The state of anthelmintic resistance in Scottish sheep flocks was evaluated during April-August 2000 using in vitro bioassays, egg hatch assays for detecting thiabendazole (TBZ) resistance and larval development assays for levamisole, ivermectin and TBZ resistance. Anaerobic sampling kits and detailed questionnaires outlining farm demographics and current(More)
Thirty-eight sheep flocks, predominantly from the south/central Scotland, were examined using a faecal egg count reduction test (FECRT) for the presence of ivermectin (IVM) resistant nematodes. Efficacies of less than 95%, 14-17 days post-treatment, were identified in 6 of 17 naturally grazing flocks where pre-treatment faecal egg counts were in excess of(More)
Resistance to Fasciola hepatica was shown by a 64 per cent reduction in fluke recovery compared with control rats was recorded in rats inoculated with serum from sheep experimentally infected with F hepatica. A comparable reduction (55.6 per cent) was obtained using transfer factor prepared from lysed leucocytes of infected rats. No significant reduction(More)
Several recent studies have emphasised the need for a more integrated process in which researchers, policy makers and practitioners interact to identify research priorities. This paper discusses such a process with respect to the UK water sector, detailing how questions were developed through inter-disciplinary collaboration using online questionnaires and(More)
An electrophysiological method is described for measuring the potassium permeability (PK) of the perineurium of the sciatic nerve of the frog. The method is based on the principle of grease-gap recording, in which an insulating compartment separates two surface recording electrodes. The sciatic nerves of frogs Rana temporaria and R. pipiens were isolated(More)
Chicken adenoviruses were isolated from asymptomatic chickens on each of 7 farms tested; a majority of them induced cytopathology by the second serial passage. Although adenoviruses were isolated from chickens ranging in age from 8 to 34 weeks, the highest isolation rate was from those 8 to 14 weeks. Eight serotypes (1, 2, 4, 5, 6, 7, 8, and 9) were(More)
