Herbicide effects on Bdellovibrio bacteriovorus

Creator:: Wehr, Nancy Briggs
Abstract:: Bdellovibrio bacteriovorus is a small parasitic bacterium present in soil, mud, and aquatic habitats. Due to its lysis of Gramnegative bacteria, an important role in soil ecology has been suggested for this organism. A study of effects of herbicides upon Bdellovibrio might consequently be of considerable value. In this study...

Materials associated with the DNA fraction of Bacillus subtilis W168

Creator:: Laudermilk, Patricia Joan
Abstract:: The purpose of this research was to determine if a basic protein was associated with the DNA of Bacillus subtilis W168, and to determine if there was a difference in the amount and type of protein associated with the DNA at different times during the growth cycle of the organism....

Structural effects on Arthrobacter ATCC 25581 methylene hydroxylase activity

Creator:: Hayasaka, Steven Shin
Abstract:: Arthrobacter ATCC 25581, capable of subterminal oxidation of n-hexadecane to 2-, 3-, and 4- alcoholic and ketonic products, was examined for the ability of this methylene hydroxylase capability to be induced and repressed, and for structural relationships influencing methylene function oxidation. Induction was best carried out by use of n-alkanes...

Chlamydiae under stress : environmental conditions influence the production and localization of chlamydial antigens

Creator:: Brown, Wendy J.
Abstract:: Chlamydiae are obligate intracellular pathogens that cause several serious conditions within the human host. Many of the symptoms associated with infection are thought to stem from the development of aberrant, or persistent, chlamydiae. Factors leading to chlamydial persistence include deprivation of amino acids, the release of certain cellular factors, or...

Evaluation of a potential Chylamydia psittaci vaccine candidate using recombinant vaccinia virus encoding the infection-specific C. psittaci GPIC proteins IncA and TroA

Creator:: Werth, Eric P.
Abstract:: Members of the family Chlamydiae cause a wide range of diseases. Chlamydia trachomatis and C. pneumoniae are most commonly associated with human disease. C. psittaci and C. pecorum are largely animal pathogens, although C. psittaci can cause pneumonia in the elderly and immunocompromised. A vaccine against these pathogens is desirable,...

Survival of fecal coliform bacteria in sludge-amended soils

Creator:: Hartel, Peter G.
Abstract:: A study was conducted to determine the effects or temperature, solar radiation, rainfall, and saturated flow on fecal coliform numbers in sewage sludge-amended soils. To determine this, four 4.6 X 13.7 m field plots were each amended in summer and in winter with 800 liters of anaerobically-digested sewage sludge, and...

Ecological study of aquatic myxobacteria in a woodland stream

Creator:: Carlson, René Virginia
Abstract:: Most studies of bacteria in water have concerned public health; little attention has been given to organisms which are indigenous to the aquatic environment. Myxobacteria are known to occur in soil, in the marine environment, and several have been studied in relation to diseases of salmonid fishes. However, little information...

Bacterial Resistance to Antisense Peptide-Phosphorodiamidate Morpholino Oligomers

Creator:: Puckett, Susan E., Reese, Kaleb A., Mitev, Georgi M., Mullen, Valerie, Johnson, Rudd C., Pomraning, Kyle R., Mellbye, Brett L., Tilley, Lucas D., Iversen, Patrick L., Freitag, Michael, and Geller, Bruce L.
Abstract:: Peptide phosphorodiamidate morpholino oligomers (PPMO) are synthetic DNA mimics that bind complementary RNA and inhibit bacterial gene expression. (RFF)₃RXB- AcpP PPMO (R, arginine; F, phenylalanine; X, 6-aminohexanoic acid; B, β-alanine) is complementary to 11 bases of the essential gene acpP (encodes acyl carrier protein). The MIC of (RFF)₃RXB-AcpP was 2.5...
