incidence of mycobacterium paratuberculosis in raw sheep and goats' milk in england, wales and northern ireland.a blind survey of 104 raw sheep and goats' milk samples (90 goat, 14 sheeps) from bulk tanks on farms throughout england, wales and northern ireland was carried out over a 5-month period (january-may 1998) in order to determine the incidence of mycobacterium paratuberculosis. each milk sample (100 ml) was divided into two 50ml portions. one portion was decontaminated with 0.75% hexadecylpyridinium chloride for 5h before culture on slopes of herrold's egg yolk medium and in bactec radiometric med ...200111230934
comparisons of original laboratory results and retrospective analysis by real-time reverse transcriptase-pcr of virological samples collected from confirmed cases of foot-and-mouth disease in the uk in 2001.there were 2030 designated cases of foot-and-mouth disease (fmd) during the course of the epidemic in the uk in 2001 (including four from northern ireland). samples from 1720 of the infected premises (ips) were received in the laboratory and examined for either the presence of fmd virus (virological samples from 1421 ips) or both fmd virus and antibody (virological and serological samples from 255 ips) or antibody alone (from 44 ips). the time taken to issue final diagnostic results ranged from ...200616980522
coxiella burnetii (q fever) seroprevalence in cattle.human cases of q fever appear to be common in northern ireland compared to the rest of the british isles. the purpose of this study was to describe the seroepidemiology of coxiella burnetii infection in cattle in northern ireland in terms of seroprevalence and determinants of infection. a total of 5182 animals (from a stratified systematic random sample of 273 herds) were tested with a commercial c. burnetii phase 2 igg elisa. a total of 6.2% of animals and 48.4% of herds tested positively. resu ...201019480726
pattern and mechanism of traumatic amputation by explosive blast.the mechanism of traumatic amputation of limbs by explosion is presented. a survey of blast casualties from northern ireland revealed that amputations through joints were very uncommon--the principal site was through the shaft of the long bones. computer modelling of a bone exposed to blast forces reinforced the hypothesis developed from the casualty survey, that the primary mechanism of the bone injury was the direct coupling of the blast wave into the tissues. the fracture occurs from the resu ...19968606410
serological surveillance for maedi-visna virus and caprine arthritis-encephalitis virus in northern ireland.the results of serological testing for maedi-visna virus infection in indigenous and non-indigenous sheep in northern ireland, over a five year period (1980 to 1984) are presented. in tests carried out in 1980 and 1981 on pedigree breeds, 10 reactors were identified on seven farms and maedi-visna virus was isolated on three occasions from leucocyte cultures. none of the animals showed clinical signs of maedi-visna and all the reactors were subsequently destroyed. nine of the reactors were import ...19863010539
