Evolution of a streamlined cooperator in Pseudomonas aeruginosa quorum sensing

Creator:: Huie, Jessica L.
Abstract:: Social behavior leading to the production of common goods is prone to exploitation. One such behavior in Pseudomonas aeruginosa is quorum sensing (QS), by which the bacteria produce signals to regulate extracellular common goods. Exploitation comes in the form of cheaters which have a mutation in the central quorum sensing...

A Digenean Metacercaria (Apophallus sp.) and a Myxozoan (Myxobolus sp.) Associated with Vertebral Deformities in Cyprinid Fishes from the Willamette River, Oregon

Creator:: Kent, M. L., Watral, V. G., Whipps, C. M., Cunningham, M. E., Criscione, C. D., Heidel, J. R., Curtis, L. R., Spitsbergen, J., and Markle, D. F.
Abstract:: A high prevalence of vertebral deformities has been observed in various fishes, especially cyprinids, from certain regions of the Willamette River for many years. One proposed source of these deformities is exposure to toxicants. Histological evaluation of affected chiselmouth Acrocheilus alutaceus revealed that all lesions associated with vertebrae were associated...

Studies on host range, fine structure, and nucleic acids of lactic streptococcus bacteriophages

Creator:: Nyiendo, Joanne Annette
Abstract:: The most frequent cause of insufficient acid production during fermentation of dairy products is bacteriophage infection of lactic starter cultures. Previously, efforts to minimize this problem have dealt primarily with the host range relationships of the viruses and susceptibility patterns of the lactic streptococci. This study was undertaken to characterize...

Final report : environmental stresses and skeletal deformities in fish from the Willamette River, Oregon, USA

Creator:: Villeneuve, Daniel L., Curtis, Lawrence R., Jenkins, Jeffrey J., Warner, Kara E., Tilton, Fred A., Kent, Michael L., Watral, Virginia G., Cunningham, Michael E., Markle, Douglas F., Sethajintanin, Doolalai, Krissanakriangkrai, Oraphin, Johnson, Eugene R., Grove, Robert Allan, Anderson, Kim A., Oregon State University.

Department of Fisheries and Wildlife, and Institute for Natural Resources
Abstract:: The Willamette River, one of only 14 American Heritage Rivers, flows through the most densely populated and agriculturally productive region of Oregon. Previous biological monitoring of Willamette River fish detected elevated frequencies of skeletal deformities in fish from certain areas of the lower (NP [NP], rivermile [RM] 26-55) and middle...

Automated and Accurate Estimation of Gene Family Abundance from Shotgun Metagenomes

Creator:: Nayfach, Stephen, Bradley, Patrick H., Wyman, Stacia K., Laurent, Timothy J., Williams, Alex, Eisen, Jonathan A., Pollard, Katherine S., and Sharpton, Thomas J.
Abstract:: Shotgun metagenomic DNA sequencing is a widely applicable tool for characterizing the functions that are encoded by microbial communities. Several bioinformatic tools can be used to functionally annotate metagenomes, allowing researchers to draw inferences about the functional potential of the community and to identify putative functional biomarkers. However, little is...

Partial purification and properties of a columnaricin isolated from the myxobacterium Chondrococcus columnaris

Creator:: Needleman, David Sol
Abstract:: Of the 14 strains of Chondrococcus columnaris examined, 4 produced antagonistic substances that inhibited the growth of other strains of this species. The antagonistic substance produced by strain 3-P63-12 was examined in greater detail. Since the inhibitory substance had an extremely narrow spectrum of activity, and was not transmissible in...

Bacteriophages for Leuconostoc oenos : a survey of Oregon wineries

Creator:: Eschelbach, Matthew Michael
Abstract:: A study of malolactic bacteria of the Leuconostoc genus, especially L. oenos, and their bacteriophages was conducted. A search for the presence of infectious bacteriophages in grapes, musts, and juices employed in malo-lactic fermentation (MLF) was conducted; no evidence, either physical or biological, was found for the existence of these...

The role of costimulation and adjuvants in the development of T cell effector and memory responses

Creator:: Maxwell, Joseph R.
Abstract:: T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

Investigations of T cell costimulation and autoimmunity in mice, and development of flow cytometric methods to assess lymphocyte stimulation in dogs

Creator:: Weatherill, Amy R.
Abstract:: Proper immune function is indispensable, as failure to mount an immune response against a pathogen can lead to serious complications or even death. T cells act by enhancing the activation of phagocytic cells as well as the activation of B cells. Their widespread influence on an immune response makes optimal...
