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...

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....

Pathogenic and molecular characterization of three closely related isolates of infectious pancreatic necrosis virus (IPNV)

Creator:: Bruslind, Linda D.
Abstract:: Three closely related isolates belonging to the A₁ serotype of infectious pancreatic necrosis virus (IPNV) were selected for comparison, to provide insight into the nature of variation in the virulence of IPN viruses. Brook trout fry (Salvelinus fontinalis) were experimentally infected with the three isolates by immersion. Cumulative mortalities over...

Transcriptional regulation of Rhizobium meliloti nitrogen fixation genes

Creator:: Evans, Paul D.
Abstract:: The transcriptional promoter sequences for the Rhizobium meliloti nitrogen fixation genes nifA and nifB were cloned to a β-galactosidase gene fusion plasmid vector and transferred by homologous recombination to a specialized transducing phage. The promoter fusions were then transduced to a recombination deficient strain of Escherichia coli as single-copy lysogens...

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,...

Effect of feeding concentrates of Lactobacillus organisms on intestinal colonization by Escherichia coli in swine

Creator:: Muralidhara, K. S.
Abstract:: A Lactobacillus species of human intestinal origin (strain MLC) used in swine feeding experiments was characterized using biochemical, genetic and serological techniques and found to be Lactobacillus lactis. Bottle feeding of the MLC strain in concentrate form (> 10⁹ cfu/ml) resulted in a reduction in both fecal coliforms and the...

Symbiotic and saprophytic characteristics of a soil population of Rhizobium leguminosarum bv. trifolii

Creator:: Yap, Kathryn H. M.
Abstract:: Although much has been learned about the comparative nodulating behavior of simple mixtures of rhizobial strains under non-soil situations, it is unclear how these findings relate to the factors influencing nodulation success by the complex mixtures of strains found within soil-borne rhizobial populations. Information on the structure and physiological behavior...
