foot-and-mouth disease in british deer: transmission of virus to cattle, sheep and deer.after exposure for two hours to cattle with foot-and-mouth disease, each of the five species of deer found in the british countryside became infected. clinical disease was typical and severe in the roe and muntjac deer, with some animals dying, less severe in the sika deer and usually subclinical in the fallow and red deer. each species transmitted disease to its own species and to cattle and sheep. the amounts of virus present in the blood, and in oesophageal/pharyngeal samples and excreted as ...1975167503
host-pathogen interactions in scrapie.there are many strains of the agent which causes scrapie and these can be used singly or given as mixed infections to investigate the ways in which agent and host control mechanisms interact during the pathogenesis of the disease. two genes in mice are described; one only affects the kinetics of the disease when extraneural injections are used, the other acts irrespective of the route of injection and it is suggested that it determines the structure of a multimeric agent-replication site, the nu ...1975807505
trends in salmonella food poisoning in england and wales 1941-72.cattle and pig herds and flocks of domestic fowl have formed the main reservoir of human salmonella food poisoning in england and wales from 1941 to 1972. changes in the incidence of human salmonella food poisoning and in the serotypes of salmonellas isolated from human infections are shown to have been associated with the introduction of new foods, with changes in animal husbandry, and with changes in the relative proportions of flesh food from different species consumed. new foods, dried powde ...19751054731

liver fluke in great britain: a survey of affected livers.over a period of 15 months data were collected from abattoirs in great britain on 213,082 cattle and 362,838 sheep livers to determine the distribution and prevalence of damage by fasciola hepatica. the stock came from 8239 farms, and from livestock markets in 81 counties. 53 per cent of the farms had sent affected stock, with significant percentages in eastern as well as the western counties of england and scotland. 21 per cent of all cattle and 7 per cent of all sheep livers examined were affe ...19751202744
the population dynamics of nematode parasites of sheep in northern england.an investigation into the population dynamics of sheep nematodes was carried out between april 1970 and september 1971. faecal egg counts were made from both ewes and lambs at weeks intervals while grass samples were taken fortnightly throughout the summer and monthly during the winter. from these results absolute numbers of nematode eggs and infective larvae were estimated and these figures used as a basis for determining the level of mortality occurring during development from egg to infective ...19751215681
the occurrence of eimeria marsica in the domestic sheep in england and wales.eimeria marsica restani 1971 is re-described from oocysts recovered in pure culture from experimentally infected coccidia-free lambs. the ellipsoidal oocysts, which measure 19-1 x 13-1 mum, possess an inconspicuous micropylar cap. the prepatent period varies from 14-16 days. e. marsica is recorded for the first time from sheep in england.19761256907

incidence of salmonella infection in animals in england and wales 1968--1974.of a total of 23,609 incidents of salmonella infection reported during the period 1968--74, 20,326 occurred in cattle, 1744 in poultry and other birds, 675 in sheep, 558 in pigs and 306 in other species of animals. despite the large number of serotypes isolated (153), 88% of incidents were due to only two stereotypes: s. dublin (15,929 incidents of which 15,446 occurred in cattle ) and s. typhimurium (4842 incidents of which 3785 occurred in cattle and 732 in birds). s. choleraesuis was the thir ...1977319168
the prevalence of sarcocystis spp in dogs and red foxes.protozoan parasites of the genus sarcocystis have been recognised for many years as intramuscular cysts of numerous vertebrates. it is only comparatively recently that the two-host nature of the life cycle has been recognised and that the intramuscular cysts are a stage in the developmental cycle of coccidian parasites of flesh eating mammals (fayer 1974, fayer and johnson 1973, 1974, rommel and others 1972, dubey 1976). carnivores ingest the intramuscular cysts from herbivores and presumably fr ...1978416553
serological studies of mucosal disease virus in england and wales.a survey of the cattle population in england and wales showed that about 62 per cent of animals had neutralising (sn) antibody to bvd-md virus in their serum. fewer seropositive individuals were detected by immunodiffusion (53 per cent), and complement fixation (cf) tests (34 per cent). the prevalence of antibody was not affected by herd size, but some variation was found between various regions of the country, and the proportion of animals seropositive rose markedly with age. the immunodiffusio ...1978203990
the distribution of antibodies to border disease virus among sheep in england and wales.within a sample of the sheep population of england and wales, 10.8 per cent of 3506 individuals had immunodiffusion test antibody to bovine viral diarrhoea mucosal disease virus antigen. there were marked differences between various geographical regions in the proportion of sheep with antibody, and border disease may be more common in some areas than disease records indicate.1978214835
salmonella gona infection in sheep.a field outbreak of salmonellosis due to salmonella agona in sheep and some subsequent experimental work is described. while the field outbreak in pregnant ewes and neonatal lambs caused severe losses the experimental disease in non-pregnant sheep was mild and transient. s agona was not isolated from the carcases of the experimental sheep killed after 28 days post infection but it persisted for 69 days in the faeces of one ewe which was kept alive for three months. media comparisons indicated th ...1978654045

influence of environmental factors excluding ultra violet radiation on the incidence of skin cancer.cancers of the skin are not properly registered and our lack of precise knowledge of the influence of environmental factors is due both to a failure to report and a failure to attribute because many tumours are not recognised as due to environmental factors and escape notification due to lack of knowledge and teaching. the long latent period also interferes. the commonest cancer is squamous cell carcinoma followed by basal cell carcinoma. melanoma is exceedingly rarely environmental. the main ca ...1978719179

forecasting the incidence of parasitic gastroenteritis in lambs in england and wales.an empirical method for forecasting the incidence of parasitic gastroenteritis in sheep in england and wales is described. the level of disease in lambs in late summer depends on the date soil moisture returns to field capacity (the autumn return date) in the previous year together with rainfall from may to july in the current year. the importance of a late autumn return date and winter weather in relation to disease in stock at other times of the year is also discussed.1978741604
forecasting the peak of gastrointestinal nematode infection in lambs.the pattern of sheep nematode infective larvae on pasture shows a marked midsummer peak arising largely from the ewe peri-parturient egg output. records of larval pattern over a nine-year period were examined in relation to meteorological data, and a correlation was demonstrated between the time of the summer peak and cumulative rainfall. a "wet score" was allocated to 12-hourly rainfall figures, and a "critical index" of 440 units of wetness was shown to be necessary before the larval peak was ...1978741605
field observations on the epidemiology of abomasal parasites in young sheep during winter and spring.a flock of spring born lambs was continuously exposed to natural parasite infection from birth until selected for slaughter in groups of two or three, at monthly intervals throughout winter and spring for abomasal worm counts. meteorological data were recorded and regular estimates of infective pasture larval availability were made. parasite population changes and inhibition patterns for ostertagia spp, haemonchus contortus and trichostrongylus axei were recorded. ostertagia spp were found to su ...1979262603
the biological selenium status of livestock in britain as indicated by sheep erythrocyte glutathione peroxidase activity.the reliability of erythrocyte glutathione peroxidase activity as an indicator of selenium status in livestock is discussed. based on this measurement, a survey is described of the biological selenium status of sheep on each of 329 farms in britain. results showed that 47 per cent of these farms were probably unable to provide grazing livestock with sufficient selenium to maintain blood levels greater than 0.075 microgram per ml. increased selenium deficiency from the increasing use of home grow ...1979473499
the treatment of acute accidental hypothermia: proceedings of a symposium held at the raf institute of aviation medicine.a symposium was held at the raf institute of aviation medicine, farnborough, hampshire, on feb. 28, 1978. the purpose of the meeting was to distill up-to-date expert opinion to provide advice for those faced with the treatment of victims of exposure or cold water immersion. in particular, it was intended to recommend practical measures which could be employed in the field. however, it soon became apparent that there are large gaps in our knowledge of the physiology of hypothermia. these made the ...1979496754
