Sequencing the genome of the bacterium allowed us to investigate virulence factors and other gene products with potential as vaccines. Using knock-out mutants of A. salmonicida, we identified key virulence factors. Proteomics studies of bacterial cells grown in a variety of media as well as in an in vivo implant system revealed differential protein production and have shed new light on bacterial proteins such as superoxide dismutase, pili and flagellar proteins, type three secretion systems, and their roles in A. salmonicida pathogenicity. We constructed a whole ge- nome DNA microarray to use in comparative genomic hybridizations (M-CGH) and bacterial gene expression studies. Carbohydrate analysis has shown the variation in LPS between strains and reveals the importance of LPS in viru- lence. Salmon were challenged with A. salmonicida and tissues were taken to construct suppressive subtractive hybridization libraries to investigate differ- ential host gene expression. We constructed an Atlantic salmon cDNA microarray to investigate the host response to A.

  • Chemical Pollution of the Oceans Toxic Chemical Pollutants in the Oceans Have Been Shown Capable of Causing a Wide Range of Human Diseases
    Supplementary Appendix to “Human Health and Ocean Pollution”, Annals of Global Health, 2020 This Supplementary Appendix contains additional references and documentation supporting the information presented in the report, Human Health and Ocean Pollution. Chemical Pollution of the Oceans Toxic chemical pollutants in the oceans have been shown capable of causing a wide range of human diseases. Toxicological and epidemiological studies document that pollutants such as toxic metals, POPs, dioxins, plastics chemicals, and pesticides can cause cardiovascular effects, developmental and neurobehavioral disorders, metabolic disease, endocrine disruption and cancer. Table 1 in this Supplementary Appendix summarizes the known links between chemical pollutants in the oceans and a range of human health outcomes. The strengths of the associations listed in Table 1 vary depending on the nature of the studies establishing these associations. Some associations have been assessed in systematic reviews and meta-analyses of animal and human data.1 2 Some are single cross-sectional or case-control studies. There are now a growing number of relevant epidemiological studies, including powerful prospective cohort studies, such as the Nurses’ Health Study II and the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS)3 Findings from these investigations are strengthening the evidence base for associations between exposures to organic chemical pollutants and adverse health outcomes.

  • Common Diseases of Wild and Cultured Fishes in Alaska
    COMMON DISEASES OF WILD AND CULTURED FISHES IN ALASKA Theodore Meyers, Tamara Burton, Collette Bentz and Norman Starkey July 2008 Alaska Department of Fish and Game Fish Pathology Laboratories The Alaska Department of Fish and Game printed this publication at a cost of $12.03 in Anchorage, Alaska, USA. 3 About This Booklet This booklet is a product of the Ichthyophonus Diagnostics, Educational and Outreach Program which was initiated and funded by the Yukon River Panel’s Restoration and Enhancement fund and facilitated by the Yukon River Drainage Fisheries Association in conjunction with the Alaska Department of Fish and Game. The original impetus driving the production of this booklet was from a concern that Yukon River fishers were discarding Canadian-origin Chinook salmon believed to be infected by Ichthyophonus. It was decided to develop an educational program that included the creation of a booklet containing photographs and descriptions of frequently encountered parasites within Yukon River fish. This booklet is to serve as a brief illustrated guide that lists many of the common parasitic, infectious, and noninfectious diseases of wild and cultured fish encountered in Alaska. The content is directed towards lay users, as well as fish culturists at aquaculture facilities and field biologists and is not a comprehensive treatise nor should it be considered a scientific document. Interested users of this guide are directed to the listed fish disease references for additional information. Information contained within this booklet is published from the laboratory records of the Alaska Department of Fish and Game, Fish Pathology Section that has regulatory oversight of finfish health in the State of Alaska.

At current, it is estimated that the aquarium industry is worth about 15 billion dollars. In ornamental aquaculture and aquarium keeping, the incidence of diseases is the main quandary that emerges during culture and deplorably affects the profitability of the ventures. Diseases are caused by viruses, protozoa, bacteria, fungi, and parasites under profound culture conditions, and the likelihood of stress elevates in an immensely colossal portion of the stock. Of these, the most paramount causes of sudden fish death are infectious and bacterial diseases. Nowadays, veterinary antibiotic treatment of contaminated fish is being applied in most of the States of India. Disease obviation is often less costly than treating disease outbreaks when it is subsisting. Adopting and implementing a health management strategy would not assure a disease-free facility that ultimately leads to considerably decremented chances of dissemination of diseases.

  • The Salmon Louse Lepeophtheirus Salmonis (Caligidae) As a Vector of Aeromonas Salmonicida
    THE SALMON LOUSE LEPEOPHTHEIRUS SALMONIS (CALIGIDAE) AS A VECTOR OF AEROMONAS SALMONICIDA by Colin William Novak B.Sc., Vancouver Island University, 2009 A THESIS SUBMITTED IN PARTIAL FULLFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in THE FACULTY OF GRADUATE STUDIES (Animal Science) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) July 2013 © Colin William Novak, 2013 Abstract The sea louse, Lepeophtheirus salmonis, has been hypothesized to be a vector of fish pathogens and previous studies have isolated viral and bacterial pathogens from L. salmonis parasitizing farmed salmon. To examine the potential transmission of A. salmonicida by preadult and adult L. salmonis via parasitism of Atlantic salmon (Salmo salar), an in vivo bacteria-parasite challenge model was tested. Two pathogen challenge trials were performed, in which sea lice from donor (Aeromonas salmonicida-injected) fish were allocated among recipient fish for 14 days. Three hypotheses were examined: (i.) L. salmonis can acquire A. salmonicida from donor fish via parasitism; (ii.) A. salmonicida-exposed sea lice can transmit the pathogen to recipient Atlantic salmon via parasitism and (iii.) L. salmonis and A. salmonicida infections can cause synergistic effects on host fish. Sea lice acquired A. salmonicida externally (Trial 1 and 2, 100%) and internally (Trial 1, 100%) from parasitizing donor fish. Trial 1 (~44g fish) demonstrated a successful transfer of bacteria from lice to salmon (mucus, 100%; kidney, 77.3%), with a decrease (t = 5.29, df = 6, p = 0.00186) in mean fish condition factor and 59.1% cumulative fish mortality. Conversely, there was no evidence of bacteria transfer, no fish mortality and no decrease in mean fish condition factor in Trial 2 (~155g fish).

  • Shellfish Diseases and Their Management in Commercial Recirculating Systems
    Shellfish Diseases and Their Management in Commercial Recirculating Systems Ralph Elston AquaTechnics & Pacific Shellfish Institute PO Box 687 Carlsborg, WA 98324 Introduction Intensive culture of early life stages of bivalve shellfish culture has been practiced since at least the late 1950’s on an experimental basis. Production scale culture emerged in the 1970’s and today, hathcheries and nurseries produce large numbers of a variety of species of oysters, clams and scallops. The early life stage systems may be entirely or partially recirculating or static. Management of infectious diseases in these systems has been a challenge since their inception and effective health management is a requisite to successful culture. The diseases which affect early life stage shellfish in intensive production systems and the principles and practice of health management are the subject of this presentation. Shellfish Diseases and Management Diseases of bivalve shellfish affecting those reared or harvested from extensive culture primarily consist of parasitic infections and generally comprise the reportable or certifiable diseases. Due to the extensive nature of such culture, intervention options or disease control are limited. In contrast, infectious diseases known from early life stages in intensive culture systems tend to be opportunistic in nature and offer substantial opportunity for management due to the control that can be exerted at key points in the systems. In marine shellfish hatcheries, infectious organisms can enter the system from three sources: brood stock, seawater source and algal food source. Once an organism is established in the system, it may persist without further introduction. Bacterial infections are the most common opportunistic infection in shellfish hatcheries.

However, bacteria of this genus are isolated from many other habitats, environments, and food products. The taxonomy of this genus is complex when phenotypic identification methods are used because such methods might not correctly identify all the species. On the other hand, molecular methods have proven very reliable, such as using the sequences of concatenated housekeeping genes like gyrB and rpoD or comparing the genomes with the type strains using a genomic index, such as the average nucleotide identity (ANI) or in silico DNA–DNA hybridization (isDDH). So far, 36 species have been described in the genus Aeromonas of which at least 19 are considered emerging pathogens to humans, causing a broad spectrum of infections. Having said that, when classifying 1852 strains that have been reported in various recent clinical cases, 95.4% were identified as only four species: Aeromonas caviae (37.26%), Aeromonas dhakensis (23.49%), Aeromonas veronii (21.54%), and Aeromonas hydrophila (13.07%).

  • Assessing Disease Impacts of Hatcheries on Downstream Salmonids in the Willamette River Basin, Oregon
    AN ABSTRACT OF THE THESIS OF Michelle Jakaitis for the degree of Master of Science in Microbiology presented on November 4th, 2014. Title: Assessing Disease Impacts of Hatcheries on Downstream Salmonids in the Willamette River Basin, Oregon. Abstract approved: ____________________________________________________________ Jerri L. Bartholomew Hatcheries are often perceived as a source of pathogen amplification, potentially increasing disease risk to free-ranging populations; at the same time, free-ranging fishes may introduce pathogens into hatcheries through untreated water sources. Many pathogens exist naturally within the environment (with the exception of introduced pathogens) and the presence of a pathogen does not guarantee infection or disease (Naish, Taylor III, Levin, Quinn, Winton, Huppert & Hilborn 2007). Infections can be acute, chronic, or asymptomatic, fish may die, recover, or become carriers (Naish et al. 2007), and pathogens may be shed from any of these stages (Scottish Executive 2002). Most salmon and trout hatcheries along the Willamette River Basin, Oregon, USA, utilize an untreated river water supply for their rearing ponds and release this water, untreated, back into the river. This creates a potential for waterborne pathogens present in free-ranging hosts to be transmitted through the water supply to hatchery populations. Moreover, any hatchery epizootic can amplify pathogens and release these into the water, which could have a direct impact on free- ranging populations exposed to those pathogens in hatchery effluent. The goal of this thesis was to assess transmission of the pathogens Flavobacterium columnare, F. psychrophilum, Aeromonas salmonicida, Renibacterium salmonicida, and Infectious Hematopoietic Necrosis Virus (IHNV), at selected hatcheries in the Willamette River Basin. To accomplish this, I considered historical data and hatchery-specific and pathogen-specific factors involved in transmission and disease.
