A DNA vaccine against infectious haematopoietic necrosis virus (IHNV) is effective at protecting rainbow trout, Oncorhynchus mykiss, against disease, but intramuscular injection is required and makes the vaccine impractical for use in the freshwater rainbow trout farming industry. Poly (D,L-lactic-co-glycolic acid) (PLGA) is a U.S. Food and Drug(More)
The prevalence of renal myxosporidiosis in wild brown trout, Salmo trutta, in seven river catchments in South-West England was investigated. Three hundred and twenty-seven fish were sampled from 16 sites, of which 54 (16.5%) were found, by histological examination of the kidney, to be infected with Tetracapsuloides bryosalmonae, the causative agent of(More)
Farmed and wild salmonids are affected by a variety of skin conditions, some of which have significant economic and welfare implications. In many cases, the causes are not well understood, and one example is cold water strawberry disease of rainbow trout, also called red mark syndrome, which has been recorded in the UK since 2003. To date, there are no(More)
PROBLEM ADDRESSED In addition to clinical instruction, residents need "people" skills that will enable them to deal with all sorts of patients in difficult clinical situations. We planned a series of 12 seminars to teach these skills to first-year residents. OBJECTIVES OF PROGRAM: To ask relevant questions typical of the patient-centred approach; with(More)
Atlantic salmon Salmo salar naturally and experimentally exposed to infectious hematopoietic necrosis virus (IHNV) in British Columbia, Canada, developed antibodies against the virus. More than 50% of the fish exposed to IHNV remained seropositive for several months after the IHN epizootic had subsided. The virus itself could not be detected in asymptomatic(More)
Despite data linking amphibole asbestos exposure with production of autoantibodies, the role of autoantibodies in subsequent disease is unknown. Residents of Libby, Montana have experienced significant exposure to amphibole asbestos due to the mining of asbestos-contaminated vermiculite near the community over several decades. This population predominantly(More)
We conducted a processing plant survey to determine the prevalence of cellulitis (enlarged sternal bursa) and focal ulcerative dermatitis (FUD) in Ontario turkeys during the summer and to establish whether the two conditions were associated. A total of 11,772 birds from 24 different farms were observed at three processing plants in Ontario between June and(More)
OBJECTIVE To explore former residents' perceptions of their experience of direct supervision. DESIGN Qualitative study using in-depth semistructured interviews. SETTING Family practice unit (FPU) at Hôpital Laval in Quebec city, Que. PARTICIPANTS Twelve physicians who had been practising for 2 to 5 years and who did their family medicine residency in(More)
A panel of 15 Mycobacterium marinum isolates was characterized by biochemical tests, sequencing the ribosomal DNA intergenic spacer (ITS) region and the heat shock protein 65 gene (hsp65) and pulsed-field gel electrophoresis (PFGE). The biochemical characteristics of all isolates were similar, except for Tween 80 hydrolysis. DNA sequence of hsp65 for a(More)
We conducted a retrospective study to determine the prevalence of cellulitis condemnations in the Ontario chicken industry and the relative proportion of variation attributable to factors that vary between processors, producers, and lots and over time. The time span studied was April 1998 to April 2001. We obtained condemnation data randomly from the(More)
