Human health significance of vibrios from the aquatic environment

Creator:: Nishibuchi, Mitsuaki
Abstract:: For the enrichment and enumeration of Vibrio fluvialis, a broth medium was designed by modifying alkaline peptone (AP) medium. This new V. fluvialis enrichment medium (FEM) was shown to be more effective than AP medium in field samplings where a total of 177 samples (estuarine waters and sediment, sewage, and...

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.,...

Antimicrobial resistance and plasmid properties of Leuconostoc and group N Streptococcus

Creator:: Orberg, Paulo K.
Abstract:: A method for rapid isolation of plasmid DNA from group N streptococci was developed. Chief advantages of the method were simplicity, the utilization of microliter quantities of reagents, and the obtainment of preparations highly enriched for covalently closed circular plasmid DNA. The method was also applied to over 15 Leuconostoc...

Strain differentiation and detection of infectious hematopoietic necrosis virus

Creator:: LaPatra, Scott Edward
Abstract:: The virulence of selected isolants of infectious hematopoietic necrosis virus (IHNV) were differentiated and correlated with electrophoretic mobilities of virion structural proteins by sodium dodecylsulfate polyacrylamide gel electrophoresis. A type 1 electropherotype of IHNV was more virulent for kokanee salmon (Oncorhynchus nerka) and a type 2 strain more virulent for...

Survival and growth of pathogenic vibrios in estuarine waters and colonization of the Pacific Oyster

Creator:: Tullo, Daniel Duane
Resource Type:: Masters Thesis
Full Text:: par- ticularly interesting when discussing the current status of Vibrio ecology. 3 Several early

Studies to improve lactic acid bacterial starter cultures

Creator:: Khosravi, Lewa
Abstract:: Three commercial sausage starter cultures were grown in an internal-pH-controlled medium (PHASE 4) and in a soluble phosphate-buffered medium. The cultures were tested by comparing viable counts before and after freezing at -40 C or freeze-drying and subsequent storage for 3 months in the frozen or dried state. Strains varied...

Indigenous Rhizobium trifolii isolated from nodules of red clover grown in subclover pasture soils

Creator:: Valdivia de Capó, Blanca
Resource Type:: Masters Thesis
Full Text:: competence" has been used widely in Rhizobium ecology (Chatel and Parker, 1973; Date and Brockwell, 1978

Development of monoclonal antibodies against the myxosporean, ceratomyxa shasta, and characterization of the salmonid host response

Creator:: Bartholomew, Jerri Lee
Abstract:: Monoclonal antibodies (Mabs) were produced against the myxosporean parasite, Ceratomyxa shasta, and were characterized by indirect immunofluorescent techniques, western blot analysis, and immunoelectron microscopy. The resulting Mabs reacted specifically with the trophozoite and sporoblast stages of the parasite, but not with the mature spore, indicating that certain antigens are stage-specific....

Delineation of the composition of an indigenous soil population of Rhizobium meliloti in root nodules of uninoculated field grown Medicago sativa L.

Creator:: Jenkins, Michael B.
Abstract:: Agronomic and microbiological studies were conducted on "Anchor" alfalfa (Medicago sativa L.) established from uninoculated seed on three Aridisols in central Oregon. Significant responses to 230 Kg N per ha (NH₄NO₃), which was applied in mid-April and after each first and second harvests, were observed in yield parameters of the...
