In 1975, Fagan published a nomogram to help practitioners determine, without the use of calculator or computer, probability patient truly having condition interest given particular test result. Nomograms are very useful for bedside interpretations results, as no is perfect. However, practicality Fagan's limited by its likelihood ratio (LR), parameter not commonly reported in evaluation studies diagnostic tests. The LR reflects direction and strength evidence provided result can be computed...
Heart and skeletal muscle inflammation (HSMI) is an emerging disease of marine-farmed Atlantic Salmon (Salmo salar), first recognized in 1999 Norway, later also reported Scotland Chile. We undertook a longitudinal study involving health evaluation over entire marine production cycle on one salmon farm British Columbia (Canada). In previous cycles at this site others the vicinity, cardiac lesions not linked to specific infectious agent or were identified. Histologic assessments both live...
Dissolved oxygen (DO), an important water-quality parameter required to support aquatic life, is a critical factor for determining the general biological health of ecosystem, and concentration DO in salmon growth welfare. This study used longitudinal concentration, recorded hourly from 21 aquaculture sites, each with loggers three separate cages, four areas British Columbia, Canada, between 2015 2017. The measurements were evaluated based on recommended concentrations protection salmonids...
Connectivity in an aquatic setting is determined by a combination of hydrodynamic circulation and the biology organisms driving linkages. These complex processes can be simulated coupled biological-physical models. The physical model refers to underlying defined spatially-explicit nodes, often incorporating particle-tracking model. particles then given biological parameters or behaviors (such as maturity and/or survivability rates, diel vertical migrations, avoidance, seeking behaviors)....
Amphibian populations suffer massive mortalities from infection with frog virus 3 FV3, genus Ranavirus, family Iridoviridae, a pathogen also involved in of fish and reptiles. Experimental oral FV3 captive-raised adult wood frogs, Rana sylvatica Lithobates sylvaticus, was performed as the first step establishing native North American animal model ranaviral disease to study pathogenesis host response. Oral dosing successful LD50 102.93 2.423.44 p.f.u. for frogs averaging 35mm length. Onset...
The sea louse is considered an important ectoparasite that affects farmed salmonids around the world. Sea lice control relies heavily on pharmacological treatments in several salmon-producing countries, including Chile. Among options for drug administration, immersion represent majority of antiparasitic strategies used As a topical procedure, do not induce long lasting effect; therefore, re-infestation from neighbouring farms may undermine their efficacy. Synchronization has been proposed as...
Chronic stress is implicated in behavioral and health issues cats, but methods for recognition, evaluation, measurement of are lacking. Cortisol concentration typically used as an indicator stress.To evaluate use enzyme immunoassay to quantitate hair nail cortisol concentrations (HCC NCC) cats associations between HCC NCC behavioral, physical, environmental correlates chronic cats.Forty-eight adult, owned or community cats.Cross-sectional study. Nail clippings were collected from cats....
There is increasing public interest in the overall health of marine environment. Harbor porpoises Phocoena phocoena have a coastal distribution, and stranded animals function as sentinels for population ecosystem health. The goal this retrospective study was to join datasets from western Atlantic eastern Pacific coasts Canada investigate causes morbidity mortality species. A total 241 necropsy records were reviewed including 147 (61%) region 94 (39%) 1988 2011. cause death could be...
Sea surface temperature (SST) and salinity (SSS) are essential variables at the ocean atmosphere interface when considering risk factors for disease in farmed wild fish stocks. Ecological research has witnessed a recent trend use of digital satellite technologies, including remote-sensing tools. We explored spatial coverage remotely-sensed SST SSS data compared them with situ measurements water temperatures salinity, which led to suggested adjustments its aquaculture research. The were from...
Infectious diseases may contribute to declines in Fraser River Sockeye salmon (Oncorhynchus nerka) stocks, but a clear knowledge gap exists around which infectious agents and are important. This study was conducted to: 1) determine the presence prevalence of 46 juvenile salmon, 2) evaluate spatial patterns burden over initial seaward migration, contrasting between two years average poor productivity. In total, 2,006 out-migrating were collected from four regions along their migration...
Proficiency in animal welfare is among the core competencies of graduating veterinary students. With growing societal concern surrounding topics, it imperative that veterinarians are knowledgeable advocates for animals' welfare. However, has not been consistently integrated into school curricula; some studies suggest existing courses may have achieved their intended outcomes. This study aimed to evaluate incoming students' perceptions regarding before and after completing a newly developed...
Collection of blood from amphibians, as in other classes vertebrate animals, is essential to evaluate parameters health, diagnose hemoparasitism, identify viral and bacterial pathogens, measure antibodies. Various methods collection have been described for amphibians. Most can be cumbersome (venipucture femoral vein, ventral abdominal vein or lingual venus plexus) result pain deleterious health consequences (cardiac puncture toe-clipping). We describe an easy practical technique collect...
