Phylogenetic characterization of the epibiotic bacteria associated with the hydrothermal vent polychaete Alvinella pompejana

Creator:: Haddad, Michael Alexander
Abstract:: Symbiotic relationships of bacteria with higher organisms are commonly observed in nature; however, the functional role of these relationships is only rarely understood. This is particularly evident in epibiotic bacterial associations in the marine environment where the bacteria are often a diverse ensemble of microorganisms, thus complicating the identification of...

Intestinal Lesions and Parasites Associated with Senescence and Prespawn Mortality in Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Nervino, Stephanie A.
Abstract:: Pre-spawning mortality (PSM) presents a major problem for population recovery of spring Chinook salmon (Oncorhynchus tshawytscha) in the Willamette River basin. In certain reaches and years, PSM has exceeded 90%. Histology has been used as the primary diagnostic method to investigate PSM in the Chinook Salmon, and a collection of...

Deschutes River Salmonid Risk of Enteronecrosis in a Changing Climate

Creator:: Yusova, Sofiya
Abstract:: Ceratonova shasta is an obligate endoparasite of salmonid fish that is endemic to the Pacific Northwest of North America. The parasite has a complicated lifecycle with two distinct spore stages and two obligate hosts, a salmonid and a freshwater annelid. Myxospores released from infected salmonid hosts, infect Manayunkia occidentalis (freshwater...

Effect of Endothal and certain other selective herbicides on microbial activity in six different soils

Creator:: Au, Frederick Hung Fo
Abstract:: The effect of Endothal (3, 6-endoxyhexahydrophthalic acid), sodium pentachlorophenate (Na-PCP) and TD-47 (di-N, N-dimethylcocoamine salt of Endothal) on the microbial populations, ammonification, nitrification and respiration in six different soils was investigated. It was found that Endothal at 20 and 200 ppm had no adverse effect on the microbial population, ammonification,...

Rhizosphere microfloras associated with mycorrhizae of Douglas-fir and red alder

Creator:: Neal, John Lloyd
Abstract:: The mycorrhizal rootlets of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco.) and red alder (Alnus rubra Bong.) were extensively investigated. A jet-black mycorrhiza was found to be dominant on Douglas-fir rootlets. The fungal symbiont was identified as Cenococcum graniforme (Sow.) Ferd. and Winge. Two forms of mycorrhizae predominated on root systems of...

A comparison of soil microfungi in forest stands of Red Alder, Conifer, and Alder-Conifer mixtures

Creator:: Wicklow-Howard, Marcia C. (Marcia Cope) 1943-
Abstract:: The species composition of soil microfungal populations in-adjacent stands of red alder, conifers, and mixed alder conifer correlated strongly with the dominant vascular vegetation. A total of 92 species were isolated: 55 from the alder stand; 45 from the conifers; and 46 from the mixed alder-conifer, with few species (16,...

The lipids of spore types B, E, and F and vegetative cell types E and F of Clostridium botulinum

Creator:: Kimble, Charles E.
Abstract:: The primary purpose of this investigation was to characterize the lipids of the spores and vegetative cells of Cl. botulinum. A second purpose was to explore the possibility that lipids might serve as a means of differentiating the chiefly proteolytic Cl. botulinum type B from the nonproteolytic Cl. botulinum types...

Mechanisms of lactose metabolism by strains of Streptococcus lactis

Creator:: Walter, Leslie Alva
Abstract:: Rapid acid production by lactic streptococci used in the manufacture of fermented dairy products is essential to the economy of the industry and to the public health of consumers. There remains to developed, however, an adequate laboratory procedure to detect and distinguish between slow and fast strains of these bacteria....

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,...
