Psychrotrophic Kanagawa positive marine vibrios distinct
from V. parahaemolyticus were isolated from shellfish
collected in Yaquina Bay, Oregon. Sample enrichment in
GSTB was followed by culture isolation on TCBS agar. The
235 vibrio isolates obtained were screened for gram reaction
and morphology, Kanagawa reaction on Wagatsuma agar
and their response...
A series of four trials was conducted to evaluate activated
sewage sludge (AcSS) as a protein source. In the first trial the protein
efficiency ratio (PER) of sun-dried and auto-claved, sun-dried
AcSS was measured with rats. Growth of AcSS-fed rats was extremely
poor as compared to those rats fed casein,...

A study of the host range and distribution of ticks and chiggers
(Acari) was undertaken in two contrasting forested areas of western
Oregon. Acarines were sampled from host mammals which were
trapped along line transects laid out in both areas, each consisting of
18 stations 50 feet apart. Hosts were...
Low concentrations of hexachlorophene (HCP) inhibit a number of pyridine nucleotide-linked dehydrogenase enzymes. The I₅₀ HCP concentrations were 105 μM for pig heart isocitrate dehydrogenase (ICD), 65 μM for horse liver alcohol dehydrogenase, 39 μM for torula yeast glucose-6-phosphate dehydrogenase (G6PD), 6.0 μM for beef heart malate dehydrogenase, and 1.6...
Open field burning is the lowest-cost method of harvest residue
disposal used extensively by grass seed producers in the Willamette
Valley of Oregon. The beneficial effects of open field burning include
effective disease control and increased seed yields. However, smoke
produced by open burning in the late summer pollutes valley...
