Herbicide effects on Bdellovibrio bacteriovorus

Creator:: Wehr, Nancy Briggs
Abstract:: Bdellovibrio bacteriovorus is a small parasitic bacterium present in soil, mud, and aquatic habitats. Due to its lysis of Gramnegative bacteria, an important role in soil ecology has been suggested for this organism. A study of effects of herbicides upon Bdellovibrio might consequently be of considerable value. In this study...

Fresh water myxobacteria : a taxonomic study

Creator:: Nitsos, Peggy Koerner
Abstract:: Myxobacteria are known to occur in the aquatic environment, however, little information is available regarding the taxonomy of these organisms. This investigation was initiated in an attempt to classify a group of fresh water cytophagas on the basis of biochemical and physiological as well as cultural and morphological characteristics. The...

A bacterial disease of the American shad (Alosa sapidissima)

Creator:: Rothman, Stanley
Abstract:: For the past six years a bacterial infection has been the cause of large losses of adult, spawning, American shad (Alosa sapidissima) in the Coos, Millicoma and Smith Rivers of Oregon. There was a sizable commercial fishery for shad in these rivers and losses of fish due to this infection...

A taxonomic study on myxobacteria isolated from fish

Creator:: Porter, Sook Hee
Abstract:: While the genus Cytophaga has been defined and classified on a morphological basis, knowledge of fresh water members of this group of myxobacteria is scanty. In the present study cultural and morphological characteristics were investigated in an attempt to classify a group of fresh water cytophaga. Microscopic examination revealed all...

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...

Partial purification and characterization of hemolysin from a psychrotrophic Kanagawa positive marine vibrio

Creator:: Huggins, Susan Peters
Abstract:: 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...

Some physiological bases for survival of a marine bacterium during nutrient starvation

Creator:: Kurath, Gael
Abstract:: The physiological responses of populations of a marine Pseudomonas sp. to nutrient starvation were observed for a period of 40 days. During the first 25 days of starvation the viability of the population decreased by 99.9 percent, but thereafter the cultures maintained approximately 5 x 10⁵ viable cells per ml...

Aeromonas salmonicida and aeromonas hydrophila (liquefaciens) as pathogens of salmonid fish. A. Selective aeromonas medium. B. Comparative characteristics of virulent and avirulent strains of aeromonas salmonicida. C. Effect of water temperature on aeromonas infections

Creator:: McCoy, Ralph Hines
Abstract:: Studies were directed toward the formulation of a selective Aeromonas medium that would permit the isolation of Aeromonas species in the presence of other common bacterial flora. The final composition of this medium, PBG Agar, in grams per liter, is: Bacto-peptone, 10; Bacto-beef extract, 10; glycogen, 4; NaCl, 5; sodium...

Comparative phenotypic studies on vibrios of environmental origin that resemble human clinical isolates

Creator:: Greenwood, John David
Abstract:: A comparative investigation of the phenotypic properties of environmental and clinical strains of the lactose-positive human pathogen, Vibrio vulnificus, revealed that they are indistinguishable in traits commonly used for identification in clinical and public health laboratories. It has also been confirmed that there are other strains of undefined Vibrio spp.,...
