The Colonization Strategies of Nontypeable Haemophilus influenzae - Bacterial Colonization Factors and Vaccine Development
… factors involved in the key processes of colonization and pathogenesis, namely adherence to host tissue and evasion of the host innate immunity. We have shown that the NTHi virulence factor Protein E mediates innate immune evasion by interacting with the C-terminus of host complement …

Finding the horseshoe nail: Colonization, de-colonoization and counter-colonization in Adult and Community Education.
… time, concerns have been expressed about the colonization of community education by neo-liberalism. As a traditionally process-oriented, non-formal learning experience, influenced by the ideas of Paolo Freire, and concerned with concepts such as social justice and combating marginalization, …

Factors Governing Gastrointestinal Colonization of Candida albicans
… by which gut microbiota mediate C. albicans colonization resistance in the gut, however, are unknown. Here, we show that gut microbiota-derived short chain fatty acids (SCFA) directly inhibit C. albicans growth in vitro. SCFA inhibit C. albicans hexose uptake and induce intracellular …

Land and Colonization: A Nehinuw (Cree) Perspective
This dissertation is about land, colonization, and Indigenous people. While focusing broadly on Algonquian peoples, special attention is given to the Spruce Island Cree of Cumberland House in northeastern Saskatchewan. The use of the Nehinuw (Cree) language and cultural historical knowledge …

Forest colonization of savannas : patterns and process
… study, I explored factors that influence forest colonization in a South African savanna. I used a 50 year fire experiment in the Kruger National Park to explore patterns of forest colonization in a mesic Terminalia sericea savanna. I studied woody seedling and sapling distribution in relation to …

Characterization of Mechanisms That Mediate Cancer Metastatic Colonization
… process remain poorly understood. Metastatic colonization is the final step of the metastatic cascade whereby cancer cells form a tumor at a distant site. This final step is the culmination of clonal evolution of cancer populations that results in a highly aggressive population with enhanced …

Predicting Colonization of Microbes in the Human Gut
… emergent phenotype by these microbes is colonization resistance, the process by which a microbial community resists colonization of an exogenous microbe. This resistance barrier is critical for protecting humans from infectious enteric pathogens. However, it is detrimental to the …

Processes and Materials for Space Exploration and Colonization
… Thesis, that highly affects the proposed space colonization of Mars, is that all payload mass shipped from Earth must escape the gravity field of our planet, and lifting propellant is a significant contributor to space exploration costs. The paradigm of In Situ Resource Utilization (ISRU) is a …

Inhibition of microbial colonization of shipboard fuel systems
… of the investigation was to study the problem of colonization of shipboard fuel systems and to examine the effect of a number of environmental factors on microbial growth and survival in order to find potential preservative treatments. A variety of microbial species were isolated from samples …

Macroinvertebrate colonization and production in new experimental ponds
Benthic macroinvertebrate colonization of twelve 0.04-ha experimental ponds was studied for the 1st yr of their existence. The ponds were filled in late January 1988, and artificial substrate samples were retrieved at 4-wk intervals from February 25, 1988 to February 25, 1989. The first organisms …

Soil colonization and drought adaptation of the actinomycete Frankia
A plant bioassay was used to enumerate infectious Frankia in soil and micro- and molecular techniques were used to identify possible mechanisms by which Frankia survive drying.

Mucins regulate virulence and colonization factors in Streptococcus pneumoniae
… Second, I identify that mucins downregulate colonization factors in S. pneumoniae, modulating microbe-microbe interactions between nasopharyngeal bacteria. Together, these results uncover novel mechanisms for how mucin tames opportunistic pathogens and provides insight for the development of …

Phytoplankton colonization and seasonal succession in new experimental ponds
… Piedmont Agricultural Experiment Station. Colonization and succession of the ponds’ phytoplankton communities were investigated during the first year after filling. Taxa richness and densities, biomass as chlorophyll a, and primary productivity (in situ oxygen method) were measured. In …

Controlling Microbial Colonization and Biofilm Formation Using Topographical Cues
… of biofilms. I investigated the adhesion, colonization, and biofilm formation of the opportunistic human pathogen Pseudomonas aeruginosa on a solid coated in close-packed spheres of polystyrene, using flat polystyrene sheets as a control. The results show that, whereas flat sheets are …

Colonization dynamics of oro-gastrointestinal microbes critical to infant health
… vivo. In Chapter 5, a model for Candida albicans colonization in neonatal piglets was developed. C. albicans is a commensal fungus for which colonization mechanisms are understudied. A surveillance analysis identified a C. albicans–negative piglet population at the University of Illinois-Urbana …
