positive genetic correlation between parasite resistance and body size in a free-living ungulate population.parasite resistance and body size are subject to directional natural selection in a population of feral soay sheep (ovis aries) on the island of st. kilda, scotland. classical evolutionary theory predicts that directional selection should erode additive genetic variation and favor the maintenance of alleles that have negative pleiotropic effects on other traits associated with fitness. contrary to these predictions, in this study we show that there is considerable additive genetic variation for ...200111761070
a survey of the prevalence of escherichia coli o157 in raw meats, raw cow's milk and raw-milk cheeses in south-east scotland.2429 samples of foodstuffs were examined for the presence of verocytotoxigenic escherichia coli o157 (vtec o157) by means of immunomagnetic separation (ims) over a 2-year period commencing april 1997. specimens comprised 1190 raw meats, 500 raw milks and 739 raw-milk cheeses. the meat and cheese samples were purchased from retail premises in south-east scotland; raw milk samples were obtained directly from farms. in addition, total e. coli counts were performed on milk and cheese samples, and th ...200111407549
an outbreak of e. coli o157 infection with evidence of spread from animals to man through contamination of a private water outbreak of e. coli o157 infection occurred in the highland region of scotland in the summer of 1999. the source of the outbreak was traced to an untreated private water supply. all six cases identified arose in visitors to the area, and most had very limited exposure to the contaminated water. permanent residents on the same supply were unaffected. the e. coli o157 isolates from the water, sheep faeces collected from around the source and the human stool samples were indistinguishable using ...200111293673

landscape with dead sheep: what they did to gruinard the context of intensified international concern about biological weapons (bw), this article looks at the pioneering british research in this field during the second world war, which caused the long-term contamination of gruinard island in north-west scotland. public record office documents have been examined to show how scientists reported on the experiments at the time and what they thought about their (top secret) work, as well as how politicians directed their efforts and used their resul ...200212044028

epidemiology of salmonella enterica serovars enteritidis and typhimurium in animals and people in scotland between 1990 and 2001.two serovars of salmonella which are currently of particular importance in both human and animal infections are salmonella enterica serovars enteritidis phage type 4 (pt4) and typhimurium definitive type 104 (dt104). this paper describes the trends in the relationships between the levels of infection of people and a range of farm animal species with these two serovars and explores some of the reasons behind them. in 1996, there was a peak of 520 reports of s typhimurium dt104 infection in people ...200314620550
foot and mouth epidemic reduces cases of human cryptosporidiosis in scotland, rates of cryptosporidiosis infection in humans peak during the spring, a peak that is coincident with the peak in rates of infection in farm animals (during lambing and calving time). here we show that, during the outbreak of foot and mouth disease (fmd) in 2001, there was a significant reduction in human cases of cryptosporidiosis infection in southern scotland, where fmd was present, whereas, in the rest of scotland, there was a reduction in cases that was not significant. we asso ...200312934196
