  • Significance of pigments in radiation resistance of Micrococcus radiodurans

    Creator:
    Krabbenhoft, Kenneth Louis
    Abstract:
    An ecological study of a microorganism similar to that isolated in 1956 and designated as Micrococcus radiodurans indicated that the organism could be isolated from several different environments. By taking advantage of its radio-resistivity, high levels of gamma radiation were used in the isolation procedures to inactivate most of the...

  • The response of nitrifying bacteria to treatments of N-Serve and Roundup in continuous-flow soil columns

    Creator:
    Rhodes, Albert N.
    Abstract:
    This study examined the effects of Roundup [N-(phosphonomethyl) glycine] and N-Serve [2-chloro-6- (trichloromethyl) pyridine] on nitrifying organisms in static batch, perfusion soil columns, and a new continuous-flow soil column system. The continuous-flow method is new to nitrification studies and was shown to produce greater nitrifier activity than either static batch...

  • A comparison of radiation induced lipid changes in Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa

    Creator:
    Ley, Ronald Douglas
    Abstract:
    Quantity variations in pigments and lipid classes were determined following γ-irradiation of Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa. Pigmentation was determined by extraction with organic solvents and measured as optical density at 475 mμ for M. radiodurans and S. lutea, and 410 mμ for Ps. E aetuginosa. Pigments of...

  • Growth and development of tetracycline resistant Chlamydia suis

    Creator:
    Lenart, Jennifer
    Abstract:
    Tetracycline is a front line antibiotic for the treatment of chlamydial infections in both humans and animals, and the emergence of tetracycline resistant (tet[superscript R]) Chlamydia is of significant clinical importance. Recently, several tet[superscript R] chlamydial strains have been isolated from swine (Sus scrofa) raised in production facilities in Nebraska....

  • Evaluation of peptide phosphorodiamidate morpholino oligomers as a novel antibiotic therapy

    Creator:
    Kaller, Margo
    Abstract:
    Peptide-phosphorodiamidate morpholino oligomers (PPMOs) are synthetic DNA mimics that bind and silence gene targets. Through designing PPMOs that silence essential or resistance genes in pathogens, these antisense oligomers could be utilized as novel antimicrobials. Towards this end, my thesis employed minimum inhibitory concentration assays (MICs) to identify PPMOs capable of...
