The size of the chromosome segment transduced by phage Pl.

Creator:: Cowan, Judith Harmon Miller
Abstract:: The purpose of this research was to determine whether the transducing phage Pl picks up original bacterial chromosome segments and whether these segments are always the same size. The plan of approach was to grow the donor bacteria Escherichia coli C600 gal⁺ (galactose) in minimal media containing the heavy isotopes...

Analysis of segregants of F'gal heterogenotes in Escherichia coli

Creator:: Kurahara, Carole Mahaney
Abstract:: The purpose of this study was to isolate and characterize any segregants of the heterogenotes formed from sexduction by an F' donor. Following the mating of F' W4520, carrying an F' gal₁⁺ gal₂⁺ factor, with W3350, a gal₁⁻ gal₂⁻ recipient, a number of recombinant clones were picked and examined for...

A comparative study of Clostridium botulinum strains using differential egg yolk media

Creator:: Stiebrs, Anita
Abstract:: The purpose of this study was to compare and test the efficiency of the leading kinds of media being used for the isolation and identification of Clostridium botulinum type E strains, and to develop a more reliable method and media for the differentiation of this organism based on the "pearly...

Human health significance of vibrios from the aquatic environment

Creator:: Nishibuchi, Mitsuaki
Abstract:: For the enrichment and enumeration of Vibrio fluvialis, a broth medium was designed by modifying alkaline peptone (AP) medium. This new V. fluvialis enrichment medium (FEM) was shown to be more effective than AP medium in field samplings where a total of 177 samples (estuarine waters and sediment, sewage, and...

Investigations of regulatory T cell induction by 2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin during a graft-versus-host response

Creator:: Marshall, Nikki B.
Abstract:: The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...

Molecular characterization of the proteinase and RNA-dependent RNA polymerase of Infectious Pancreatic Necrosis Virus, a fish birnavirus

Creator:: Mason, Carla L.
Abstract:: The A segment of infectious pancreatic necrosis virus (IPNV) is expressed as a polyprotein encoding three primary gene products, VP2, NS and VP3, from a large open reading frame. The nucleotide sequence for the A segment of the Sp isolate of IPNV was determined. The NS protein is the putative...

A physiological approach to a rapid method for identifying C. botulinum

Creator:: Dyer, John Kaye
Abstract:: Disc gel electrophoresis of the vegatative cell -free extracts ofstrains of Clostridium botulinum types A, B, C, E, and F and therelated nontoxic group showed limited value as a means for identifyingthese closely related microorganisms, since separation,though not consistent in all cases, could only be based on the numberof protein...

Partial purification and characterization of hemolysin from a psychrotrophic Kanagawa positive marine vibrio

Creator:: Huggins, Susan Peters
Abstract:: Psychrotrophic Kanagawa positive marine vibrios distinct from V. parahaemolyticus were isolated from shellfish collected in Yaquina Bay, Oregon. Sample enrichment in GSTB was followed by culture isolation on TCBS agar. The 235 vibrio isolates obtained were screened for gram reaction and morphology, Kanagawa reaction on Wagatsuma agar and their response...
