Creator:: Harriff, Melanie J.
Abstract:: Environmental mycobacteria are important opportunistic pathogens for many hosts, including humans, cattle, and fish. Two well-studied species are Mycobacterium avium subsp. avium, a significant cause of disseminated bacterial disease in patients with AIDS, and Mycobacterium avium subsp. paratuberculosis, the cause of Johne’s disease in cattle. Many other species that are...

Creator:: Mason, Olivia Underwood
Abstract:: Oceanic crust covers nearly 70% of the Earth's surface, of which, the upper, sediment layer is estimated to harbor substantial microbial biomass. Marine crust; however, extends several kilometers beyond this surficial layer, and includes the basalt and gabbro layers. In particular, the basalt layer has high permeabilities which allows for...

Creator:: Tripp, H. James
Abstract:: To identify factors limiting 'Candidatus Pelagibacter ubique' maximum cell density and growth rate in pure culture on seawater, the genome sequence of 'Cand. P. ubique' was analyzed, culturing experiments with organic and inorganic nutrient additions were made, and radiotracer uptake experiments were performed. The genome was sequenced, custom data mining...

Creator:: Patel, Dilip
Abstract:: Mycobacterium avium subsp. paratuberculosis (MAP) is a cause of Johne's disease (JD) in cattle and other ruminants. MAP infection in the bovine host is not well characterized. It is assumed that crossing the bovine intestinal mucosa is important for MAP to establish infection. MAP's ability to infect bovine epithelial cells...

Creator:: Starkenburg, Shawn R.
Abstract:: The chemolithoautotrophic nitrite oxidizing bacteria (NOB) participate in the biogeochemical cycling of nitrogen by catalyzing and conserving energy from the oxidation of nitrite (NO₂-) to nitrate (NO₃-) via a nitrite oxidoreductase (NXR). The main objective of this work was to comparatively annotate and analyze the genome sequences of Nitrobacter winogradskyi...

Abstract:: Tetracycline (Tet)-resistant strains of Chlamydia suis were isolated from swine farms in the Midwest. The isolation of the resistant strains was significant because Tet is an antibiotic used to treat infections by veterinarians and doctors. One of the tetracycline (Tet)-resistant strains, R19, was able to survive in Tet up to...

Creator:: Raju, Deepa
Abstract:: Clostridium perfringens type A isolates producing enterotoxin (CPE) are an important cause of both food poisoning (FP) and non food borne gastrointestinal diseases (NFBGID) in both humans and animals. C. perfringens type A food poisoning is caused by isolates carrying the CPE encoding gene (cpe) on the chromosome while the...

Creator:: Early, Julie V.
Abstract:: Mycobacterium avium cause disseminated disease in immunocompromised people such as AIDS patients. Subsequent to crossing the intestinal epithelium, M. avium thrive within vacuoles in macrophages. The bacteria exhibit a different, more invasive, phenotype after being in macrophages compared to M. avium from laboratory conditions. We hypothesized that this intracellular phenotype...
