use of long-acting oxytetracycline against pasteurellosis in lambs.the efficacy of long-acting oxytetracycline in the control of pneumonic pasteurellosis in lambs was tested on seven scottish farms. after laboratory confirmation of pasteurella-related deaths in lambs, half the lambs in each flock were given long-acting oxytetracycline (20 mg/kg intramuscularly) and half were left untreated. on three farms a single treatment was given and on four farms two doses were administered four days apart. eighteen of the 878 control lambs died as a result of confirmed pa ...19902321337

bacteriology and somatic cell counts in milk samples from ewes on a scottish farm.milk samples from 50 sheep on a single scottish research farm were collected weekly for 10 wk postpartum. samples were analyzed for somatic cell counts (scc) each week and bacteriologic culture was done for 7 of the 10 wk. a total of 492 udder half samples were cultured, of which 467 had corresponding cell count data. statistical analysis on complete scc and culture data showed no association between scc and bacterial isolation, even when more than 10 colonies of a single bacterial species were ...200415352543
prevalence of pasteurella multocida and other respiratory pathogens in the nasal tract of scottish calves.the prevalence of pasteurella multocida, a cause of bovine respiratory disease, was studied in a random sample of beef suckler and dairy farms throughout scotland, by means of a cross-sectional survey. a total of 637 calves from 68 farms from six geographical regions of scotland were sampled between february and june 2008. deep nasal swabs were taken, and samples that were culture-positive for p multocida were confirmed by pcr. prevalence of p multocida was 17 per cent (105 of 616 calves); 47 pe ...201021257416
infectious agents associated with respiratory disease in a case-control study of the infectious agents associated with natural outbreaks of respiratory disease in pheasants, 28 batches of birds from sites affected by disease and eight batches of birds from unaffected sites were examined by six veterinary laboratories in england, wales and scotland, and tested for mycoplasmas, other bacteria and viruses. sinusitis was the commonest sign of disease and was associated with mycoplasma gallisepticum as detected by pcr in the trachea (p < 0.05) and conju ...200212054135

some aspects of tick-borne diseases of british sheep.the significance of tick-borne fever (tbf) and other tick-borne diseases of british sheep are reviewed. experimental and field studies were carried out to clarify the role of tbf as a pathogen per se and as a predisposing factor in other diseases. experimental tbf infection caused anorexia and depression in two- to three-week-old lambs, which under the stress of a hill environment could alone be a cause of mortality. nine out of 10 lambs experimentally inoculated with staphylococcus aureus durin ...19863754669
molecular epidemiology of pasteurella multocida in dairy and beef calves.the molecular epidemiology of pasteurella multocida has rarely been studied at the farm level in cattle. the aim of this study was to determine whether single or multiple strains of p. multocida tend to exist within farms. molecular characterisation was carried out on isolates obtained from nasal swabs from 105 calves from 32 randomly selected beef and dairy farms located throughout scotland, and from 131 calves from 20 farms in the mayenne region of france, where sampling occurred in response t ...201121511409
