Autologous mesenchymal stem cells (MSCs) have been used as a potential cell-based therapy in various animal and human diseases. Their differentiation capacity makes them useful as a novel strategy in the treatment of tissue injury in which the healing process is compromised or delayed. In horses, bo...

Increased accountability has been a catalyst for the reformation of curriculum and assessment practices in postsecondary schools throughout North America, including veterinary schools. There is a call for a shift in assessment practices in clinical rotations, from a focus on content to a focus on as...

Several immunostimulatory feed additives have shown the ability to induce protective responses in Atlantic salmon to infection with Lepeophtheirus salmonis. However, even the most encouraging results rarely surpass a 50% protective index in the host. That fact coupled with the well-documented limita...

Background: Therapeutic decisions regarding urinalysis are commonly based on the presence of white and red blood cells. Traditionally, numbers per high-power field are estimated using wet-mount microscopic examination. This technique is not standardized and counts are likely prone to inaccuracy. In ...

Control of sea lice, Lepeophtheirus salmonis, on farmed Atlantic salmon, Salmo salar, relies heavily on chemotherapeutants. However, reduced efficacy of many treatments and need for integrated sea lice management plans require innovative strategies. Resistance to emamectin benzoate (EMB), a major se...

This study investigates the sub-chronic effects of shellfish possibly contaminated by algal toxins in albino Wistar mice. Following in-feed treatment with hepatopancreas, there were significant (p < 0.05) differences in packed cell volume, haemoglobin concentration, red blood cell count, lymphocyte ...

Anophryoides haemophila is an important protistan parasite of American lobster, Homarus americanus, as it has been found to infect lobsters in the wild as well as causing major losses of lobsters maintained in commercial holding facilities. Expression of over 14,500 H. americanus hepatopancreatic ge...

United States and Canadian governments have responded to legal requirements to reduce human-induced whale mortality via vessel strikes and entanglement in fishing gear by implementing a suite of regulatory actions. We analyzed the spatial and temporal patterns of mortality of large whales in the Nor...

Sturgeon aquaculture has increased considerably worldwide but little is known about their immunological development and competence in early life stages. Culture of larvae is one of the most critical stages in intensive sturgeon farming, often associated with high mortality rates. The objective of th...

In North America, a high mortality of soft-shell clams Mya arenaria was found to be related to the disease known as disseminated neoplasia (DN). Disseminated neoplasia is commonly recognized as a tetraploid disorder related to a disruption of the cell cycle. However, the molecular mechanisms by whic...

In the past decades, reports on bivalves' pathogens and associated mortalities have steadily increased. To face pathogenic micro-organisms, bivalves rely on innate defenses established in hemocytes which are essentially based on phagocytosis and cytotoxic reactions. As a step towards a better unders...

Parasitic copepods, in particular sea lice, have considerable impacts upon global freshwater and marine fisheries, with major economic consequences recognized primarily in aquaculture. Sea lice have been a contentious issue with regards to interactions between farmed and wild populations of fish, in...

Approximately 8 weeks after a chlorine insult associated with the city water supply, shortnose sturgeon, Acipenser brevirostrum (L.), from one group presented with small (3-4 mm) irregular foci of cutaneous pallor that involved the dorsocranial integument with progressive ulceration of the nascent l...

The control of the ectoparasite, sea lice (L. salmonis), on farmed Atlantic salmon in Eastern Canada was complicated by the development of resistance to emamectin benzoate, the primary in-feed medication used since 2000. Field efficacy and bioassay assessments were initiated to address the emergency...

Reverse transcription-real time polymerase chain reaction (real time RT-PCR) assay with Universal Probe Library (UPL) probes has been developed for the detection and genotyping of Chilean infectious pancreatic necrosis virus (IPNV) isolates from infected cell culture. Partial nucleotide sequences (1...

Detection/removal control method of Aleutian disease by CIEP detection of ADV-antibody and farm or barn depopulation/repopulation, have been the recommended approaches of AD control since mid 1970s. The detection/removal was, at least under common N. American husbandry conditions, unsuccessful in co...

OBJECTIVE: To compare the effect of xylazine bolus versus medetomidine constant rate infusion (MCRI) on serum cortisol and glucose concentrations, urine production, and anesthetic recovery characteristics in dorsally recumbent, spontaneously breathing, isoflurane-anesthetized horses. DESIGN: Prosp...

OBJECTIVE: To compare the effects of xylazine bolus versus medetomidine constant rate infusion (MCRI) on cardiopulmonary function and depth of anesthesia in dorsally recumbent, spontaneously breathing, isoflurane-anesthetized horses. DESIGN: Prospective, randomized crossover study. ANIMALS: 10 he...

Shell disease is a major threat to the American lobster ( Homarus americanus, Milne Edwards) fishery. Here we describe the composition of microbial communities associated with lesions of 2 forms of shell disease in Atlantic Canada, ( i) a trauma shell disease (TSD) characterized by massive lesions a...
