Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Nervino, Stephanie A.
Abstract:: Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...

Expanding Diagnostic Assays for Pseudoloma neurophilia & Description of the Progression of Infection in Adult Zebrafish Populations

Creator:: Schuster, Corbin J.
Abstract:: Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities and is an important threat to the zebrafish model. This microsporidian parasite can cause clinical disease, but more importantly is a causative agent of non-protocol induced variation in research. Studies utilizing infected zebrafish, could potentially confound...

Comparison of three diagnostic assays in the detection of Pseudoloma neurophilia in zebrafish

Creator:: Kreul, Taylor G.
Abstract:: As the zebrafish (Danio rerio) becomes increasingly popular as a biomedical model for various laboratory studies, the need for efficient and accurate diagnostic assays for the pathogens that infect it has grown. The most common pathogen infecting laboratory zebrafish is Pseudoloma neurophilia, a microsporidium that has been known to cause...

Controlling Important Pathogens in Zebrafish (Danio rerio) : Assessing Cryopreservation Survival of Bacteria and Parasites and Clinical Sensitivity of Mycobacterial qPCR Assays

Creator:: Norris, Lauren J.
Abstract:: Zebrafish (Danio rerio) are one of the most commonly used animal models in biomedical research. Zebrafish resource facilities, like the Zebrafish International Resource Center (ZIRC) in Eugene, Oregon, are the main providers and keepers of numerous zebrafish wild-type, mutant, and transgenic lines. Although ZIRC maintains live zebrafish at various life...

Pseudoloma neurophilia in the Zebrafish (Danio rerio) : Consequences of Infection on Neurobehavioral and Biomedical Research using a Burgeoning Model Organism

Creator:: Spagnoli, Sean
Abstract:: Since its inception as a laboratory animal in the early 1970s, the zebrafish has proven itself a rising star in the world of comparative biomedical sciences due to its short generation time, ease of care, external fertilization, and transparent larvae. In a very few decades, the zebrafish has been utilized...

An Investigation of Ceratomyxa shasta sporulation following death of itsChinook salmon host

Creator:: Soderlund, Krista M.
Abstract:: As pre-spawning mortality (PSM) in Chinook salmon in the Willamette River Valley becomes a more defined and examined area of study, more focus is granted to not only preserving the health of these fish, but also expanding knowledge concerning various pathogens that utilize the salmon as hosts and may be...

Retrospective study of the prevalence of Pseudoloma neurophilia between zebrafish sexes

Creator:: Chow, Fidelis
Abstract:: As a major biological model for biomedical research, maintaining healthy zebrafish (Danio rerio) is imperative for accurate and consistent lab results. This retrospective study focuses on Pseudoloma neurophilia, a microsporidium, because it is the most common pathogen found in laboratory zebrafish. An online database maintained by the Zebrafish International Resource...

Pseudoloma neurophilia : progression of infection and transmission characteristics of a microsporidian parasite in a model vertebrate, Danio rerio

Creator:: Sanders, Justin L.
Abstract:: The microsporidian parasite, Pseudoloma neurophilia, is the most commonly diagnosed infectious disease in laboratory populations of the zebrafish, Danio rerio. Infections by P. neurophilia are generally subclinical, however, they can become acute either incidentally or due to experimental immune suppression. Non-protocol induced variation can confound results in laboratory experiments using...

Intestinal hyperplasia and neoplasms in zebrafish (Danio rerio)

Creator:: Paquette, Colleen Elizabeth
Abstract:: Zebrafish (Danio rerio) have become an increasingly important model organism for cancer research. There are several cancer models in which neoplasms are induced chemically or genetically. However, spontaneous (unknown etiology) neoplasms are rather common in zebrafish, particularly in older fish. For over a decade, spontaneous intestinal neoplasia and preneoplastic intestinal...

Detection and transmission of Mycobacterium marinum and Mycobacterium chelonae in zebrafish (Danio rerio)

Creator:: Peterson, Tracy Shawn
Abstract:: Mycobacteriosis is a common disease of laboratory zebrafish (Danio rerio). Different infection patterns occur in zebrafish depending on mycobacterial species. Mycobacterium marinum and M. haemophilum produce virulent infections associated with high mortality, whereas M. chelonae is more wide spread and not associated with high mortality. Identification of mycobacterial infections to...
