Adaptation of molecular filtration for recovery of fish viruses from water

Creator:: Watanabe, Robin Aiko
Abstract:: The effectiveness of tangential flow filtration (TFF) for recovery of infectious hematopoietic necrosis virus (IHNV) and infectious pancreatic necrosis virus (IPNV) from large volumes of water was evaluated. In laboratory studies, virus recovery from IHNV-seeded water following concentration by TFF was approximately 13%. However, addition of 0.1 and 1% FBS...

What is killing the corals? Viral and bacterial interrogations using metagenomics and microscopy

Creator:: Soffer, Nitzan
Abstract:: Corals have multiple roles in maintaining ocean health and are some of the world’s most diverse ecosystems. The coral animal is host to a multitude of taxa, including symbiotic dinoflagellate algae, fungi, bacteria, protists, and viruses. Environmental stressors and disease agents can perturb the delicate balance of the coral host...

The Genome of Pseudomonas fluorescens Strain R124 Demonstrates Phenotypic Adaptation to the Mineral Environment

Creator:: Barton, Michael D., Petronio, Michael, Giarrizzo, Juan G., Bowling, Bethany V., and Barton, Hazel A.
Abstract:: Microbial adaptation to environmental conditions is a complex process, including acquisition of positive traits through horizontal gene transfer or the modification of existing genes through duplication and/or mutation. In this study, we examined the adaptation of a Pseudomonas fluorescens isolate (R124) from the nutrient-limited mineral environment of a silica cave...

Characterization of antibiotic resistant enteric bacteria that contaminate vegetables

Creator:: Salama, Maysoon
Abstract:: Previous studies revealed the high incidence of drug resistant bacteria from foods. In this study, market vegetables were tested for their contamination with antibiotic resistant (ABR) enteric bacteria. A total of 402 bacterial strains from surface vegetables (e.g., lettuce) and 321 from root vegetables (e.g., carrots) were examined for their...

Full Text:: circular nucleic acid elements (19, 21, 22, 40) which replicate autonomously (45) and are of various sizes

Characterization of Baculovirus genes involved in genome replication and processing

Creator:: Vanarsdall, Adam L.
Abstract:: The Baculoviridae comprise a diverse group of occluded DNA viruses that contain large double-stranded DNA genomes of 80 - 180 kb and may encode up to 180 gene products. To understand how baculoviruses replicate and process their genomes and the gene products that are involved in these events, a series...

Molecular Analysis of Environmental Water Samples as a Monitoring Method for the Fish Parasite Ichthyophthirius multifiliis

Creator:: Howell, Claire K.
Abstract:: Parasites are ubiquitous members of ecological communities, capable of contributing to the decline of vulnerable populations. Therefore, monitoring parasite level is a critical component for host management. Molecular tools, such as quantitative polymerase chain reaction (qPCR), can be valuable additions to monitoring protocols that assess parasitic disease risk to hosts....

Analysis of Mutations Affecting Cooperation in Pseudomonas aeruginosa Populations

Creator:: Robinson, Tanner M.
Abstract:: In a process called quorum sensing (QS), the bacterial pathogen Pseudomonas aeruginosa uses small diffusible signals to coordinate cooperative behaviors via secreted “public goods”. Under QS-dependent growth conditions, social cheaters arise with mutations in lasR, the gene for the primary QS signal receptor. These cheaters do not produce public goods....

Disulphide bond formation is essential for vaccinia virus late protein L1R function and for production of infectious progeny

Creator:: Blouch, Robert Edward
Abstract:: L1R, a myristylated late gene product of vaccinia virus, is essential for formation of infectious intracellular mature virions (IMV). In its absence, only viral particles arrested at an immature stage are detected and no infectious progeny virus are produced. Previous studies have shown that the L1R protein is exclusively associated...

Chromatophores as cell-based biosensors for the detection of chemically and biologically toxic substances

Creator:: Dukovcic, Stephanie R.
Abstract:: Cell-based biosensors are function-based detectors that use the physiological response of a living cell to sense biologically stimulating agents. This emerging technology extends the application of current detection methods by reporting on the toxicity of a sample and the potential to cause disease. Previously, Betta splendens erythrophores have been described...
