The objective of this study was to identify risk factors for productivity losses in the Canadian lobster industry. Lobster handling and fishing practices onboard 64 fishing boats and transportation conditions on 49 vehicles subsequently transporting these lobsters from fishing wharves to processing ...

Two clones of 1.4 and 4.33 kilobase pairs (kbp) DNA inserts, were selected from a Sarcocystis cruzi sporozoite genomic library constructed in bacteriophage lambda gt10. These clones strongly hybridized with sporozoite and merozoite DNA and were evaluated as probes for detection of merozoite DNA in c...

The scuticociliate Anophryoides haemophila, causes bumper car disease in American lobster (Homarus americanus) in commercial holding facilities in Atlantic Canada. While the parasite has been recognized since the 1970s and much has been learned about its biology, minimal molecular characterization e...

Studies were undertaken to monitor for the presence of Borrelia burgdorferi, the etiologic agent of Lyme disease, on Prince Edward Island, Canada. Gut contents were removed for culturing from seven engorged ticks collected in 1991-1992 including five Ixodes dammini (Spielman, Clifford, Piesman &...

A genomic library of Sarcocystis cruzi sporozoite DNA was constructed in bacteriophage lambda gt10. Recombinant phages containing insert DNA were selected by growth on Escherichia coli strain C600 hflA150. Of 14 clones examined, 11 contained DNA inserts ranging in size from approximately 1.45 kiloba...

Visceral and systemic infection with a Dermocystidium -like organism was diagnosed recently in post-seawater entry smolts of Atlantic salmon farmed in the Bay of Fundy. In late summer and early fall, young fish developed "black smolt" disease, characterized by anorexia, lethargy and black skin. Para...

This case report provides pathologic and confirmatory molecular characterization of an outbreak of bumper car disease caused by the scuticociliate Anophryoides haemophila in American lobster Homarus americanus, from a commercial holding facility in Nova Scotia, Canada. Although sporadically and anec...

Sporozoites of S. hirsuta, although they also penetrated into bovine monocytes, developed to the schizogonous phase only in bovine pulmonary artery endothelial cells. Schizonts were evident from 14 days after sporozoite inoculation (DAI) and persisted to 62 DAI, when experiments were terminated. Mer...

Spores identified as Myxobolus neurobius were found in head homogenates of both wild young Atlantic salmon Salmo salar and Arctic char Salvelinus alpinus . Formalin-preserved spores from Atlantic salmon measured an average of 12.9 x 9.4 mu m and contained two polar capsules that measured 6.4 x 2.9 m...

The levels of production, ascarid burden and respiratory disease were measured on 15 purposively selected swine herds, and the relationships between the various measures of ascarid burden were examined. On each farm 30 randomly selected pigs were weighed and rectal fecal samples were collected at ap...

Proteinase K was used for the cleaning of Sarcocystis cruzi (Apicomplexa) sporocysts prior to excystation. Bovine pulmonary endothelial cell cultures inoculated with the excysted sporozoites remained free of bacterial contamination for the duration of the experiment and had high yields of merozoites...

The principal lesions due to the ciliate Anophryoides haemophila in experimentally infected lobsters are observed in the gills and connective tissue from the 9th week post-infection. These lesions were not related to the inoculum of parasites and were consistent in all inoculum studies (2000, 10 000...

Mushroom tyrosinase (E.C. 1.14.18.1) was evaluated as a control material for use in a plasma prophenoloxidase assay in the American lobster Homarus americanus as part of the assay's validation procedure. Reconstituted. lyophilized tyrosinase solution was stable for 72 h at 2-4degreesC. Percent ...

The purpose of this research was to investigate the salinity and formalin sensitivity of a ciliate parasite (Anophryoides haemophila) of the American lobster (Homarus americanus), and to examine the target-animal (lobster) safety of chemical-bath treatments involving low salinity, formalin, or chlor...

Reference ranges for blood chemical and cellular components in the "healthy" population of interest are required to identify alterations in individuals in association with disease and disorders. The purpose of this study was to determine reference ranges for various constituents of hemolym...

Chronic mortalities in lumpfish Cyclopterus lumpus reared in a saltwater recirculation system were associated with the presence of an intranuclear microsporidian. Morphological changes were characterized by infiltration of lymphocyte-like cells predominantly in the renal interstitium and also in the...

The pathology caused by the ciliate Anophryoides haemophila was studied in experimentally infected lobsters. The first lesions due to the parasite were observed in gills and connective tissue from 9th week post-infection for the lower inocula and at week 4 for the 500,000 ciliate inoculum.. These le...

Adult ticks were found on 2 cats and a dog in the Charlottetown area between June and November 1989. The 3 ticks were identified as I. dammini. Serum samples from the 2 cats were examined for antibodies to Borrelia burgdorferi; IFA titres were less than 1:32 in both cats. It is uncertain whether in ...

Neoparamoeba pemaquidensis continues to be an ongoing problem for commercial finfish aquaculture and has also sporadically been associated with mass mortalities of commercially relevant marine invertebrates. Despite the ubiquity and importance of this amphizoic amoeba, our understanding of the biolo...
