By cross hybridization with the mammalian growth-related protein, GAP-43, we have isolated several Drosophila cDNAs and genomic sequences. These sequences correspond to a single copy gene that encodes two developmentally regulated transcripts 2.4 and 2.0 kb in length. The predicted protein sequence ...

A young, female llama (Lama glama) was euthanized following the onset of hindleg paresis and paralysis. Live trematodes, identified as Fascioloides magna, were identified from the liver of this animal. This represents the first report of F. magna in a llama.

A new species of trichosomoidid nematode, Huffinanela canadensis n. sp., is described from the skin of rockfish (Sebastes spp.) from the Pacific Ocean off the coast of Vancouver Island (Clayoquot Sound region), British Columbia, Canada, on the basis of the morphology of the adult worms and their egg...

The efficacy of closantel against experimentally induced Fascioloides magna infection in sheep was studied. In each of 3 experiments, closantel was administered 8 weeks after the sheep were given (oral inoculation) 100 metacercariae of F magna. In the 1st experiment, closantel was given orally to 5 ...

Described are the first antemortem diagnosis made via fecal examination using the Baermann technique and the first postmortem recovery of endemic Angiostrongylus vasorum in dogs from North America, specifically the Avalon peninsula of Newfoundland. In one dog, A. vasorum was recovered and identified...

Tissue samples and feces were collected from a dead, adult female coyote (Canis latrans) found at the side of the road in late March 2003 in the Avalon Peninsula region of Newfoundland, Canada. The coyote apparently died of vehicular-related trauma. Samples of lung, brain, heart, liver, and kidney w...

Angiostrongylus vasorum, French heartworm, is a metastrongloid parasite found in the pulmonary arteries and right ventricle of wild and domestic canids and various other animals. The natural definitive hosts are species of foxes. The geographic distribution of the parasite includes various countries...

Cestodes are hermaphroditic flatworms (tapeworms) consisting of a scolex, neck region, and repeating segments. Cestodes lack a mouth, intestine, and body cavity. Life cycles are indirect, with the definitive host acquiring the adult form of the tapeworm by the ingestion of the larval metacestode sta...

Members of an Ahousaht First Nations community of Vancouver Island, Canada have developed a market for wild-caught species of indigenous rockfish (Sebastes spp.). The fish, which are caught by hook and line, are transported live to fish markets in Vancouver. Recently, market place downgrading of the...

Crenosoma vulpis and Eucoleus aerophilus are nematode parasites that can cause verminous pneumonia in wild carnivores. There is a paucity of information regarding the distribution of parasites in the lungs and the relationship between histopathological and parasitological diagnoses in naturally infe...

The roles of water temperature, flow, and agitation on the development and settlement of sea lice (Lepeophtheirus salmonis) on their Atlantic salmon (Salmo salar) hosts were investigated in the laboratory. In the first phase, fish were exposed to 5, 10, or 15 degree C and increased water-flow (18 L/...

The roles of water temperature, flow and agitation on the development and settlement of sea lice on their Atlantic salmon hosts were investigated in the laboratory. In the first phase, fish were exposed to 5, 10 or 15 degrees C and increased water-flow (18 vs. 6 litre/min). In the second phase, fish...

The long-term (i.e., 4-5 months) effects of large doses (3 X 50 mg/kg) of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) on striatal dopamine-containing afferents were studied in the NMRI strain of mice. Recently improved in vivo electrochemical methods were first used to examine the magnitude,...

Enzyme-linked immunosorbent assays (ELISAs) have been used as a diagnostic tool to quantify levels of gastrointestinal nematodes in dairy cattle by measuring Ostertagia ostertagi antibodies in milk. Higher levels of O. ostertagi antibodies measured by ELISA methods, referred to as optical density ra...

Experiments were conducted to determine the effects of sea lice, Lepeophtheirus salmonis, on non-specific defence mechanisms in Atlantic salmon, Salmo salar, by experimentally infesting hatchery-reared 1 and 2 year old post-smolts, S1 and S2, with laboratory grown infective copepodids at moderate to...

The effects of Lepeophtheirus salmonis, on non-specific defence mechanisms in Salmo salar, were determined by experimentally infesting 180 hatchery-reared post-smolts with laboratory-grown infective copepodids at moderate to high infection intensities ranging from 15 to 285 lice per fish. The effect...
