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
procedures for large-scale antiserum production in sheep.the increased cost of maintaining and purchasing small laboratory animals used in the production of large quantities of antiserum resulted in a search for a more suitable animal. this paper describes the procedures used to raise antisera in scottish mountain sheep.1975807656

a five-year study of the epidemiology of fascioliasis in the north, east and west of scotland. 1977608065
a study of a strategic dosing programme against ovine fascioliasis on a hill farm.in a farm-scale veterinary preventive programme run from 1973 to 1976 the use of rafoxanide (flukanide; merck sharp & dohme) in the prophylaxis of ovine fascioliasis resulted in a marked reduction in the percentage of ewes passing fluke eggs in the faeces and an absence of clinical cases of fascioliasis throughout these years. three separate flocks of hill sheep were used in this study in which the aim of the dosing programme followed was to kill the majority of liver flukes (fasciola hepatica) ...1977878250
a survey of rotaviruses in sheep in scotland. 1977867760
studies of louping-ill virus (flavivirus group) in wild red grouse (lagopus lagopus scoticus).studies were made to find evidence of louping-ill virus infection in free-living red grouse and relate this to their breeding success. in areas where ticks were abundant 61 (84%) adult grouse had antibody to the virus compared with 1 (10%) in areas where ticks were relatively scarce. of 162 chicks tested 25 were shown to be viraemic. infected chicks were of significantly less weight than comparably aged uninfected birds and the probability that they died was much greater than that of uninfected ...1978212479
immunoglobulin concentrations in scottish blackface lambs on a hill farm.the serum immunoglobulin concentration in one- to 11-day-old scottish blackface lambs born outdoors on a hill farm were very similar to those in scottish blackface lambs born indoors on an experimental lowland farm. the concentrations were significantly higher in single lambs than in twins, and in lambs which survived for six months than in lambs which died, and showed significant annual variations which could not be related to the weather. they were significantly correlated with the ages of the ...1978653126

a study of the effects of copper deficiency in scottish blackface lambs on improved hill pasture.one member of each pair of twin lambs from 37 five-and six-year-old scottish blackface ewes, grazing reseeded pasture suspected of causing a molybdenum-sulphur induced copper deficiency in sheep, was given an injection of 12.5 mg copper calcium edetate at about eight weeks of age. plasma copper concentrations of these lambs were maintained in the normal range by further injections of copper as required (treatment group). the remaining member of each twin pair received no copper therapy (control ...1979573017
field studies on enzootic abortion of ewes in south east scotland.statistical data were collected from 20 sheep flocks in which enzootic abortion of ewes (eae) was diagnosed by examination of fetal material and maternal blood samples. the abortion rate in the 10,645 ewes in these flocks was 7.6 per cent. thirteen of the flocks were fully vaccinated against eae but the abortion rate in these was still in the order of 6.5 per cent. eae was the major cause of the problem as ascertained from the laboratory examination of samples from a wide range of cases of abort ...1979552732
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

virus infections in cattle and sheep in scotland 1975-1978.over the four-year period 1975-78 attempts were made to identify virus in samples from 1231 outbreaks of disease in cattle, and 682 outbreaks of disease in sheep. a virus identification was possible in 26 per cent of these disease outbreaks. the nature and significance of these virus infections is discussed.19806244693
a survey of sheep losses and their causes on commercial farms in the north of scotland.a three year survey on sheep deaths and their causes was conducted on 10 commercial farms in the north of scotland. diseases and other trauma associated with the perinatal period accounted for 56.81% of all ewe deaths, while pneumonia, parasitic gastroenteritis, torsion of the bowel and haemorrhagic enteritis (redgut) accounted for a further 21.7%. no one disease condition predominated in the rams and hoggs. in lambs, most deaths occurred between birth and four days old (77.86%). causes came in ...19807361390
flies associated with cattle in south west scotland during the summer months.the sheep headfly, hydrotaea irritans, and morellia simplex were the species most frequently associated with cattle at pasture and comprised 69.01 per cent and 13.93 per cent, respectively, of the total fly collection made from grazing cattle. the most prevalent biting fly was haematobosca stimulans which comprised 4.46 per cent of the total catch. a few clegs, haematopota pluvialis, and horse flies, hybomitra distinguenda, were also recorded. a few of the headflies swarming around cattle entere ...19817244374
investigations on a babesia isolated from scottish sheep.the pathognomic, serologic and morphometric identity of a babesia sp. recently isolated from sheep in argyllshire was studied. initially, problems were encountered due to the occurrence of eperythrozoon ovis as a contaminant of the isolate and treatment with neoarsphenamine failed to remove it. finally, a combination of oxytetracycline therapy and rapid passage allowed isolation of the babesia sp. and its preservation in the form of a glycerolized, infected blood stabilate. inoculation of the st ...19817329723
copper poisoning in sheep from north ronaldsay maintained on a diet of terrestrial herbage.copper toxicity occurred in north ronaldsay sheep fed on a diet of terrestrial herbage relatively high in molybdenum. five sheep were taken from the island of north ronaldsay, orkney to the veterinary investigation centre at thurso and fed solely on the herbage of the laboratory paddocks, supplemented in winter by hay made from these paddocks. the level of copper, molybdenum, zinc and total sulphur in the terrestrial herbage was analysed, together with the seaweeds which form the major part of t ...19827147642

salmonella montevideo infection in sheep and cattle in scotland, 1970-81.outbreaks of abortion associated with infection by salmonella montevideo have affected sheep in the east, especially the south-east, of scotland each year since 1972. disease in the north and north-east was usually less severe. between 1 january 1970 and 31 december 1981, a total of 67 incidents affecting sheep were reported by veterinary laboratories to the communicable diseases (scotland) unit, 87% of which presented during the main lambing months of february, march and april. twenty-one episo ...19836833746
the herring gull larus argentatus as a likely transmitting agent of salmonella montevideo to sheep and cattle.this paper presents evidence for the involvement of herring gulls (larus argentatus) as vectors in the recent outbreaks of salmonella montevideo in sheep and cattle in scotland and suggests that the transfer can take place over considerable distances. the breeding area in scotland of herring gulls which overwinter in n.e. england is remarkably similar to the geographical distribution of the outbreaks. this pattern, together with the feeding behaviour of herring gulls on farmland, the presence of ...19836663059
outbreak of listeria meningoencephalitis in young lambs.an outbreak of listeriosis occurred in five-week-old lambs in a flock of 200 dorset ewes and 240 lambs in-wintered. nine lambs were lost within a period of 10 days. no cases of stillbirth or abortion or cerebral listeriosis occurred in the ewes. silage had been fed on this farm to both cattle and sheep for 10 years without any previous problems. a description of the outbreak and the findings are reported.19836415890

sheep histocompatibility antigens: a population level comparison between lymphocyte antigens previously defined in france, england and scotland, and sheep red cell groups.a comparison test was performed to look for correlations between the three nomenclature systems for sheep histocompatibility antigens which have been previously described in france, england and scotland. 187 french sheep from a wide variety of breeds were typed for lymphocyte antigens with antisera which detect the ola, p and ed series of antigens; they were also tested against 387 uncharacterized french antisera. six clusters of sera were found which showed correspondence between antigens of at ...19854003855
prolonged gestation in sheep in western scotland associated with diffuse neuronal necrosis of the fetal central nervous system.a specific disorder of sheep resulting in gestation periods extending up to eight months is reported for the first time. the condition, which is of low prevalence, occurs on hill farms in coastal regions of western scotland and affected ewes usually die unless relieved of their fetuses by surgery. the fetuses may weigh up to 12 kg and have long hairy coats, skeletal deformities, precocious gonadal development and extensive liquefaction of central nervous system tissue. the aetiology has not been ...19854049701
an epidemiological study of salmonella montevideo by biotyping.among 622 cultures of salmonella montevideo, 27 biotypes belonging to two biogroups were recognized. one biogroup (10di) was predominant in all animals in scotland but only in sheep in england and wales. the other (biogroup 2d) was responsible for almost all human, cattle and poultry infection in england and wales, but only 24% of human infection in scotland.19854020111
ovine listerial encephalitis: analysis, hypothesis and synthesis.analysis of field data suggested that listerial encephalitis in sheep was most common in winter and early spring in the age groups of sheep which would be cutting, changing and possibly losing teeth. it was hypothesised that under these conditions ingested listeria monocytogenes could reach the fine dental terminals of the trigeminal nerve causing an ascending neuritis and encephalitis. experimental inoculation of organisms into the dental pulp demonstrated the feasibility of this route of infec ...19854002594
epidemiology of nematodirus battus infection in eastern scotland.a field investigation was carried out from 1981 to 1983 on the prevalence of nematodirus battus under different systems of lowland sheep management. pasture larval counts, ewe and lamb worm egg counts, and tracer lamb worm counts were carried out. as expected, contamination was generally greater on permanent pasture than on new leys as measured by pasture larval counts and lamb worm egg counts. however significant contamination was also recorded on young grass fields for which alternate grazing ...19854001558

further investigations of a hydatid focus in north-west scotland.a serological survey carried out on 1379 school-children from skye and mallaig in the n.w. of scotland failed to show evidence of subclinical cases of hydatidosis. there appeared to be a relatively low level of exposure to the parasite, as judged by elisa and iha tests. thirty-one children reacted positively in the elisa; only one child had a transient positive result in the iha test. surveillance of these children will be continued for the present but the duration required is uncertain. the loc ...19863950391
border disease without nervous signs or fleece changes.a natural infection with border disease virus occurred in a flock on low ground in argyll in the spring of 1984. the outbreak was unusual in that the typical clinical signs of border disease, ie, tremor and, or, fleece changes were not present; manifestations of disease were restricted to abortion and the birth of small weak lambs. the disease was shown to have been introduced to the flock by four healthy ewes persistently infected with border disease virus among a group of 39 purchased in octob ...19873576934
