Pathogenicity of Phytophthora species from Oregon waterways

Creator:: Navarro, Sarah M.
Abstract:: Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....

Coliform bacteria associated with redwood and drinking water emanating from redwood tanks

Creator:: Morrow, Jan Elaine
Abstract:: Coliform contamination of a rural water system led to a research project investigating the problems surrounding storage of drinking water in redwood tanks. Field studies of redwood tanks presently in use showed development of large coliform populations (notably, Klebsiella and Enterobacter species) soon after tanks were put into use. This...

Ecological study of aquatic myxobacteria in a woodland stream

Creator:: Carlson, René Virginia
Abstract:: Most studies of bacteria in water have concerned public health; little attention has been given to organisms which are indigenous to the aquatic environment. Myxobacteria are known to occur in soil, in the marine environment, and several have been studied in relation to diseases of salmonid fishes. However, little information...

Specific indicator organisms can define the magnitude and origins of non-point pollution in rural environments

Creator:: Lamka, Karla Gail
Abstract:: A comprehensive study was made on the impact to surface and ground water pollution by a recently populated rural neighborhood located in the foothills of western Oregon. A stream originating in a limited access forest and flowing through a modern zoned housing development was routinely monitored. Sampling was performed during...

Bacteria-phosphate interactions in Upper Klamath Lake sediments

Creator:: Harrison, Michael John
Abstract:: Interactions between sediment bacteria and available phosphate necessary for algal production in a eutrophic lake were studied. Twenty percent of the organisms isolated solubilized phosphate forms such as CaHPO₄, Ca₃(PO₄)₂, FePO₄, Mg₃(PO₄)₂ and Al₂(PO₄)₂. Solubilization of phosphates occurred under conditions of aerobic growth. Upon quantitative analysis, some isolates were capable...

Poliovirus adsorption by soil particles in seawater

Creator:: Jakubowski, W. (Walter)
Abstract:: This investigation was initiated in an attempt to delineate some factors affecting the adsorption of poliovirus to soil particles in seawater. The results could have significance in the development of assay procedures for viral contaminants in natural waters. A sample of marine sediment, obtained from an estuary near Purdy, Washington,...

The simultaneous expression of metal tolerance and antibiotic resistance by bacteria from drinking water systems

Creator:: Calomiris, Jon James
Abstract:: Previous studies of six Oregon public water supply systems revealed that greater proportions of the standard plate count (SPC) bacteria from distribution waters were multiple antibiotic resistant (MAR) compared to isolates from the corresponding source raw waters. In the present study, two of these water systems were examined further to...

Persulfate oxidizable carbon as an index of organic pollution in wastewater

Creator:: Purkerson, L. Lee
Abstract:: Methods for the detection and measurement of waste materials in water have lagged far behind the many complex problems facing workers in the water pollution field. The present study introduces a new method for the detection and measurement of organic pollution in water. This new method, the persulfate oxidation, is...
