The prevalence of Giardia duodenalis, Cryptosporidium spp. and other intestinal parasites was determined in dogs <1 year old from Prince Edward Island, Canada. Fecal samples were collected from the local animal shelter (n=62), private veterinary clinics (n=78) and a pet store (n=69). Intestinal para...

The adult American lobster (Homarus americanus) is susceptible to few naturally occurring pathogens, and no viral pathogen is known to exist. Despite this, relatively little is known about the H. americanus immune system and nothing is known about its potential viral immune response. Hundreds of rur...

A small commercial hunt for 5-7 weeks old grey seals (Halichoerus grypus) occurs intermittently around the Canadian Maritime provinces and may expand in the near future. We sought to better understand and, where possible, improve the harvesting methods of this hunt. We compared the use of the regula...

We investigated the interaction of temperature and copper (Cu) on mitochondrial bioenergetics to gain insight into how temperature fluctuations imposed by natural phenomena or anthropogenic activities would modulate the effects of Cu on cellular energy homeostasis. Mitochondria were isolated from ra...

The goal of the present study was to elucidate the modulatory effects of cadmium (Cd) on hypoxia-reoxygenation-induced mitochondrial dysfunction in light of the limited understanding of the mechanisms of multiple stressor interactions in aquatic organisms. Rainbow trout (Oncorhynchus mykiss) liver m...

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...

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...

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...

Parasitic sea lice are a major challenge for salmon aquaculture. This is especially due to recent development of resistance to emamectin benzoate (EMB) in the parasite. We investigated 1) whether EMB treatment success in Grand Manan, Bay of Fundy, NB, can be explained through EMB bioassay and P-gp ...

Congenital Anomalies of the Kidney and Urinary Tract (CAKUT) are a polymorphic group of clinical disorders comprising the major cause of renal failure in children. Included within CAKUT is a wide spectrum of developmental malformations ranging from renal agenesis, renal hypoplasia and renal dysplasi...

Background: The proportion of geriatric horses within the equine population has increased in the past decade, but there is limited information on the immune function of these animals. Hypothesis: Aged horses will have a lesser increase in serum antibody response to vaccination. Animals: Thirty-four ...

A dog adopted as a stray in Spain and then brought to Canada 4 years prior to presentation was evaluated for polyarthritis. An electrophoresis showed a marked polyclonal gammopathy and synovial smears contained leishmanial organisms within macrophages.

Studies on the microanatomy of the mucus-rich biofilm surface of normal or damaged teleost skin tissue have been limited because conventional fixation regimes do not effectively retain mucus during tissue preparation. A non-aqueous fixation method, based on a technique devised to retain airway mucou...

Infectious salmon anaemia (ISA) virus (ISAV) is a fish orthomyxovirus that has recently been assigned to the new genus Isavirus within the family Orthomyxoviridae. It possesses the major functional characteristics of the virus family including haemagglutinating, receptor destroying enzyme (RDE), and...

A thymoma was tentatively diagnosed by radiographic and cytologic examination in a dog with hypercalcemia and elevated serum parathyroid hormone-related protein (PTHrP) concentration. Following surgical excision, the diagnosis of thymoma was confirmed via histopathologic examination, the hypercalcem...

Domoic acid (DOM), the toxin involved in amnesic shellfish poisoning, was presented to live mussels (at 5 degree C, 28 ppt) in dissolved form (125 nM) and as food encapsulated in liposomes. Less than 1% of dissolved DOM and up to 6% of food-borne DOM was incorporated into mussel tissues. DOM absorbe...

A Clydesdale mare was examined for weight loss, inappetence, ptyalism, and dysphagia. The main abnormality revealed by serum biochemistry was a marked hyperglobulinemia, and protein electrophoresis revealed a monoclonal gammopathy in the gamma region. The urine was positive for Bence Jones proteins....
