Two epidemiological studies in central Haiti

Creator:: Bonnlander, Heinke P.
Abstract:: Two epidemiological studies, designed to expand our knowledge of morbidity and mortality indicators concerning malaria and Bacillus Calmette-Guerin vaccination in the Hospital Albert Schweitzer health district located in Central Haiti's Artibonite Valley, are presented. The hospital serves a rural population of 190,000 in its 610 square mile district. A large...

Phylogeny of the "Chaoboriform" genera

Creator:: Ogawa, Joshua R.
Abstract:: The phantom midges (Diptera: Chaoboridae) are a relatively small fly family composed of 50 extant species in six genera. Larvae are of interest to limnologists and ecologists because of their tolerance to toxicants, predatory avoidance strategies, and the role chaoborids play in zooplankton community dynamics. Relative to mosquitoes, systematists have...

Epidemiological implications of sporozoite aggregation in malaria vectors

Creator:: Li, Xiaohong, 1963-
Abstract:: This study describes and quantifies some microprocesses of malaria transmission including blood vessel location by Anopheles stephensi and sporozoites delivery of An. stephensi infected by Plasmodium berghei. The study models the effects of malaria parasite-induced changes in probing behavior and mosquito mortality on disease transmisson. Finally, host, vector, and parasitological...

Benthic biological invasions in two temperate estuaries and their effects on trophic relations of native fish and community stability

Creator:: Castillo, Gonzalo C.
Abstract:: The extent of biological invasions, their role on the feeding of native fishes and their impact on community stability were investigated in Alsea Bay and Yaquina Bay, two estuaries on the central Oregon coast, USA. Most nonindigenous species (NIS) introduced in these intermediately invaded estuaries are considered byproducts of culturing...

What Makes a Fish Resistant? Comparative Genomics and Transcriptomics of Oncorhynchus mykiss with Differential Resistance to the Parasite Ceratonova shasta

Creator:: Barrett, Damien E.
Abstract:: The myxozoan Ceratonova shasta is an intestinal parasite of salmon and trout that causes ceratomyxosis, a disease characterized by severe inflammation of the intestine that can lead to hemorrhaging, necrosis, and death of the fish host. The parasite is endemic to the Pacific Northwest of the United States and Canada,...

How Do Parasites Infect Salmon? Comparative Transcriptomics Reveal Myxozoan Adaptations for Parasitism

Creator:: Americus, Benjamin
Abstract:: The phylum Cnidaria contains three main branches: Anthozoa (corals, sea anemones) Medusozoa (jellyfish, hydra), and Endocnidozoa. This latter branch is characterized by parasitism and contains the microscopic fish-parasites Myxozoa. Myxozoa are highly simplified, consisting of only a few cell types, however they have retained the nematocyst stinging cells and complex...

Harnessing Heterogeneity in Human Gut Microbiome Data

Creator:: Tataru, Christine
Abstract:: The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

Recruiting physicians in Oregon : recruitment theory and practical strategies

Creator:: Seifert, Nancy L.
Abstract:: This research sought to identify the reasons physicians attributed for practicing in Oregon, the reasons for relocating out of Oregon, and the reasons for failures in recruiting physicians to Oregon. A random sample survey of 494 Oregon physicians identified the presence of economic and non-economic factors related to the recruitment...
