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 ...

This study assessed the standard urinalysis technique and sediment stain techniques as predictors of bacterial culture results for canine and feline urine. Canine (n = 111) and feline (n = 79) urine samples were evaluated using unstained wet-mount and air-dried Gram and Wright-Giemsa stained sedimen...

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...

Microsporidial gill diseases particularly those caused by Loma salmonae incur significant economic losses to the salmonid aquaculture industry. The gill responses to infection include the formation of xenomas and the acute hyperplastic inflammatory responses once the xenomas rupture releasing infect...

Systemic inflammatory responses of mammals and bony fish are primarily driven by coordinated up-regulation and down-regulation of plasma acute-phase proteins. Although this general principle is believed to be universal among vertebrates, it remains relatively unexplored in elasmobranchs. The objecti...

A cross-sectional study was undertaken to determine the prevalence and distribution of Salmonella serotypes from apparently healthy slaughtered sheep and goats from November 2002 to May 2003 at Debre Zeit abattoir, Ethiopia. From a total of 107 slaughtered animals (60 goats and 47 sheep), 642 sample...

An automated colorimetric method for determining lipase activity in canine sera was evaluated for precision, linearity and correlation to existing assay methods. The colorimetric method was a commercial reagent that used a series of enzymatic reactions based on the hydrolysis of 1,2 diglyceride by p...

Three calves from a herd of beef cattle were examined because of disproportionate dwarfism and excessive extension of metacarpophalangeal and metatarsophalangeal joints. Abnormalities had been noticed at birth, 1 to 6 days earlier. A thorough herd investigation revealed that 16 calves born to 70 mul...

Severe generalized degenerative myopathy was diagnosed in a population of captive bred satanic leaf-tailed geckoes (Uroplatus phantasticus). The diagnosis was based on characteristic histological changes and response to dietary therapy. This is the first reported case of nutritional myopathy in the ...

OBJECTIVE: To determine the FIV status of Australian cats with lymphosarcoma and relate this to patient characteristics, tumour characteristics (tissue involvement, histological grade and immunophenotype), haematological and serum biochemical values and FeLV status of affected cats. DESIGN: Prospect...

From winter 1997 to summer 1998, an epizootic of salmonellosis affected several species of songbirds over a large area of the eastern North American continent. This article describes the details of this epizootic in the Canadian Atlantic provinces, based on laboratory examination of dead affected bi...

The potential for cross-transmission of Perkinsus karlssoni from bay scallops Argopecten irradians to various native Atlantic Canadian species of shellfish was investigated. Lateral proximal transmission was investigated whereby infected moribund bay scallops were maintained with uninfected individu...

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 ...

In the summer of 1999, the incidence of Salmonella enterica serotype infantis infections in Alberta rose dramatically. Subsequent laboratory and epidemiological investigations established that an outbreak of human disease caused by this organism was occurring across Canada and was associated with pe...
