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....

Studies on roles of lactic acid bacteria and yeast in the flavor of bakery products

Creator:: Yamada, Masahiko
Abstract:: Roles of lactic acid bacteria in flour pre-ferment and white bread were investigated. Volatile compounds produced by the organisms were identified using gas-liquid chromatography (GLC). Lactic acid bacteria were isolated from domestic commercial compressed yeast and active dry yeast. Numbers per gram of sample were 10⁸ to 10⁹ in compressed...

Lactic streptococci: growth characteristics and plasmid profiles of drug- and bacteriophage-insensitive mutants

Creator:: Wulf, John J.
Abstract:: Fast acid-producing streptomycin-resistant mutants for several strains of lactic streptococci currently used in commercial Cheddar cheese manufacture were isolated. Their isolation involved use of a recently developed differential plating medium that allows identification of fast acid-producing colonies. Both parents and mutants were characterized with regard to growth, acid production, proteolytic...

Disease models and infectious phenotypes of Mycobacterium avium subspecies paratuberculosis

Creator:: Everman, Jamie L.
Abstract:: Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne's disease, a chronic inflammatory bowel disease that affects ruminant populations worldwide. The characteristic stages of the disease make diagnosis difficult, resulting in silent transmission among animals in a herd for years before proper detection of the infection. The extensive...

Bacterial 16S ribosomal DNA analysis of pyrrolizidine alkaloid detoxifying enrichments from the ovine rumen

Creator:: Gray, Diane R.
Abstract:: Bacterial cultures enriched from sheep rumen fluid have demonstrated the ability to detoxify pyrrolizidine alkaloids (seneciphylline and jacobine) in tansy ragwort (Senecio jacobaea). The microbes are difficult to isolate using classical anaerobic techniques, therefore, microbes from two different enrichment cultures demonstrating similar degradation activity were identified using their 16S ribosomal...

Construction of a model organism for performing calcium carbonate precipitation in a porous media reactor

Creator:: Kaufman, Megan J.
Abstract:: Aquifers are an important storage location and source of fresh groundwater. They may become polluted by a number of contaminants including mobile divalent radionuclides such as strontium-90 which is a byproduct of uranium fission. A method for remediating such divalent radionuclides is sequestration through co-precipitation into calcium carbonate. Calcium carbonate...

Influence of temperature on the associative growth of Streptococcus thermophilus and Lactobacillus bulgaricus

Creator:: Radke-Mitchell, Lyn C.
Abstract:: Optimum growth temperatures were determined for nine strains of Streptococcus thermophilus and ten strains of Lactobacillus bulgaricus, all commercial yogurt or yogurt starter isolates. Optimum growth temperatures ranged from 35 C to 42 C for S.thermophilus strains, averaging 38.6. Optimum growth temperatures for L.bulgaricus strains ranged from 43 C to...

Fecal Bacteroidetes host distributions and environmental source tracking

Creator:: Dick, Linda K.
Abstract:: Contamination of recreational and shellfish waters with fecal pollution is a major water quality issue with associated economic impacts and human health risks. Reliable fecal source identification and rapid, quantitative analyses are essential components of risk assessment. Enteric bacteria that are endemic to specific hosts have a potential role as...
