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...

Transformation of alfalfa using Agrobacterium tumefaciens

Creator:: Gelford, Inga L.
Abstract:: Agrobacterium tumefaciens, the causative agent of crown gall disease, does not readily infect commercial varieties of alfalfa (Medicago sativa). Cloned virulence genes from the megaplasmid pTiBo542 have been shown to enhance Agrobacterium host range and infectivity on dicotyledonous plants. To obtain a gene transfer system for commercial alfalfa cultivars, an...

Mechanisms of lactose metabolism by strains of Streptococcus lactis

Creator:: Walter, Leslie Alva
Abstract:: Rapid acid production by lactic streptococci used in the manufacture of fermented dairy products is essential to the economy of the industry and to the public health of consumers. There remains to developed, however, an adequate laboratory procedure to detect and distinguish between slow and fast strains of these bacteria....

Survival and persistence of Bacteroidales human and ruminant specific fecal markers and occurrence with fecal pathogens

Creator:: Walters, Sarah P.
Abstract:: Aquatic fecal contamination from non-point sources impairs environmental health and serves as a vehicle for transmission of waterborne disease, resulting in economic losses worldwide. Accurate methods of diagnosing fecal pollution and its source are needed to prevent human exposure, remediate pollution, and reduce economic impacts. In order to obtain this...

Marine bacterioplankton abundances and distributions

Creator:: Morris, Robert M.
Abstract:: Microorganisms play key roles in ocean biogeochemistry. However, several predominant groups of uncultured bacterioplankton thought to contribute to important biogeochemical processes in the oceans are known primarily from gene cloning studies. Although these studies have greatly expanded our view of microbial diversity in the oceans, they are not quantitative and...

Effect of feeding concentrates of Lactobacillus organisms on intestinal colonization by Escherichia coli in swine

Creator:: Muralidhara, K. S.
Abstract:: A Lactobacillus species of human intestinal origin (strain MLC) used in swine feeding experiments was characterized using biochemical, genetic and serological techniques and found to be Lactobacillus lactis. Bottle feeding of the MLC strain in concentrate form (> 10⁹ cfu/ml) resulted in a reduction in both fecal coliforms and the...

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...

The Genome of Pseudomonas fluorescens Strain R124 Demonstrates Phenotypic Adaptation to the Mineral Environment

Creator:: Barton, Michael D., Petronio, Michael, Giarrizzo, Juan G., Bowling, Bethany V., and Barton, Hazel A.
Abstract:: Microbial adaptation to environmental conditions is a complex process, including acquisition of positive traits through horizontal gene transfer or the modification of existing genes through duplication and/or mutation. In this study, we examined the adaptation of a Pseudomonas fluorescens isolate (R124) from the nutrient-limited mineral environment of a silica cave...

Cloning, sequence and expression of the glycoprotein gene of infectious hematopoietic necrosis virus, a fish rhabdovirus

Creator:: Feyereisen-Koener, Josette
Abstract:: Double-stranded cDNA was prepared from infectious hematopoietic necrosis virus mRNA and cloned into the plasmid vector pUC8. A cDNA clone (pG8) containing the entire coding region for the glycoprotein (G-protein) of infectious hematopoietic necrosis virus was selected by hybridization to a ³²P-labeled probe. The restriction map and nucleotide sequence of...
