Molecular characterization of infectious hematopoietic necrosis virus transcription and genome organization

Creator:: Kurath, Gael
Abstract:: The transcription process of infectious hematopoietic necrosis virus (IHNV), a rhabdovirus of salmonid fish, was studied both in vivo and in vitro. Polyadenylated RNA from IHNV infected-salmon cells was resolved electrophoretically into five bands, one of which was found to contain two mRNA species. The molecular weights and intracellular molar...

A molecular study of viral proteins in the pathogenesis of infectious hematopoietic necrosis virus

Creator:: Chiou, Pinwen Peter
Abstract:: The role of viral proteins in the pathogenesis of infectious hematopoietic necrosis virus (IHNV) was studied at the molecular level. The expression of the viral genes at the protein and RNA level, and their cellular localization, were characterized to further our understanding of viral pathogenesis. The pathogenic effect of individual...

Studies to improve lactic acid bacterial starter cultures

Creator:: Khosravi, Lewa
Abstract:: Three commercial sausage starter cultures were grown in an internal-pH-controlled medium (PHASE 4) and in a soluble phosphate-buffered medium. The cultures were tested by comparing viable counts before and after freezing at -40 C or freeze-drying and subsequent storage for 3 months in the frozen or dried state. Strains varied...

Distribution of Clostridium botulinum type E in fish, shellfish and the marine environment of the Pacific Northwest, and protein patterns of the toxigenic and non-toxigenic stains

Creator:: Craig, James Morrison
Abstract:: Interest in the distribution of Clostridium botulinum type E was heightened by the sudden outbreak of human botulism from smoked whitefish chubs and canned tuna fish in 1963. The question arose as to how widely the organism is distributed among fish and shellfish in the Northwest and what potential hazard...

Physical and functional characterization of soluble protein antigen(s) produced by Renibacterium salmoninarum

Creator:: Turaga, Prasad S. D.
Abstract:: Renibacterium salmoninarum produces bacterial kidney disease (BKD) in salmonid fish. Soluble antigen(s) (SA) produced by the bacterium was characterized by physicochemical, functional and immunological methods. The molecular weight determination by SDS-PAGE analysis of SA yielded 14 different molecular weight species. Seven of these species were prominent, 57 kd protein being...

Studies on growth metabolites produced by Propionibacterium shermanii

Creator:: Salih, Mohammed Ali
Abstract:: The ability of Propionibacterium shermanii to produce growth metabolites which were inhibitory to food spoilage indicator organisms was investigated. Asperqillus niqer, a Pseudomonas species and Kluyveromyces fraqilis were the spoilage indicators chosen to represent molds, gram negative psychrotrophic bacteria and yeasts, respectively. Supplementation of milk or whey based media was...

Secreted Agrobacterium rhizogenes Effector Protein GALLS Interacts with Arabidopsis Host Proteins and Stimulates Agrobacterium-mediated Transformation

Creator:: Wei, Wei
Abstract:: Agrobacterium species transform plant cells by targeting a portion of plasmid-encoded bacterial DNA to the host nucleus. Genetic transformation by A. tumefaciens and A. rhizogenes requires secreted effector proteins. The tumor-inducing (Ti) plasmid from virulent A. tumefaciens encodes VirE2, a secreted single-stranded DNA-binding protein required for efficient transformation of hosts....

Properties of Pseudomonas aeruginosa resistant to quaternary ammonium compound

Creator:: Washam, Clinton Jay
Abstract:: Pseudomonas aeruginosa cells were selected for their ability to grow in the presence of 750 ppm alkyldimethylethylbenzyl ammonium chloride (QAC). These cells were found to retain their resistance to the germicide throughout tri-weekly transfers for 7 months in tryptone glucose yeast extract (TGY) broth containing no QAC. Comparisons of the...

Characterization of Mycobacterium avium subsp. hominissuis Interactions with Host Macrophages and Multinucleated Giant Cells

Creator:: Joseph, Jayanthi J.
Abstract:: To examine the macrophage response to M. avium, I compared inflammasome and cytosolic sensor expression and activation. My result demonstrated that virulent strains of M. avium (A5 and 104) suppress IL-1β production and induce IFN-β production in macrophages. M. avium mutants deficient at DNA export in the biofilm exhibited reduced...

Characterization of microaggregate formation by Mycobacterium avium subspecies hominissuis

Creator:: Babrak, Lmar
Abstract:: Mycobacterium avium subsp hominissuis (MAH) is an opportunistic environmental pathogen that causes respiratory and gastrointestinal illness in immunocompromised persons such as those with chronic respiratory diseases or AIDs, respectively. In recent years, there has been a significant increase in the incidence of nontuberculous mycobacterial (NTM) lung infections, including in cystic...
