Developing Risk Assessment Maps For Schistosoma Haematobium In Kenya Based On Climate Grids And Remotely Sensed Data, Kelsey Lee Mcnally Jan 2003

Developing Risk Assessment Maps For Schistosoma Haematobium In Kenya Based On Climate Grids And Remotely Sensed Data, Kelsey Lee Mcnally

LSU Master's Theses

It is important to be able to predict the potential spread of water borne diseases when building dams or redirecting rivers. This study was designed to test whether the use of a growing degree day (GDD) climate model and remotely sensed data (RS) within a geographic information system (GIS), could be used to predict both the distribution and severity of Schistosoma haematobium. Growing degree days are defined as the number of degrees centigrade over the minimum temperature required for development. The base temperature and the number of GDD required to complete one generation varies for each species. A monthly climate …


Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins Jan 2003

Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins

LSU Master's Theses

Among the gastrointestinal nematode parasites that cause the most problems to small ruminants, Haemonchus contortus is one of major concern. Currently, the control of H. contortus and others is almost entirely based on the use of anthelmintics. Consequently, anthelmintic resistance has developed worldwide and this has become a serious problem in small ruminant nematode parasite control programs. In view of this, there is a need for alternative control methods. The use of Copper-Oxide Wire Particles (COWP) to help reduce parasite burden is one such alternative. Three trials were conducted to determine the effect of COWP on the reduction of H. …


Susceptibility Of Bacillus Anthracis To Gamma And Cherry Bacteriophage, Preston A. Fulmer Jan 2003

Susceptibility Of Bacillus Anthracis To Gamma And Cherry Bacteriophage, Preston A. Fulmer

LSU Master's Theses

Bacillus anthracis is a bacterium that causes severe disease mainly in ruminants, but can affect any mammal, including humans. A popular method for the detection of this organism is susceptibility of the bacterial isolate to g bacteriophage. However, to date no study on the resistance of a wide variety of B. anthracis isolates has been conducted. The following study examines the rate of resistance of a wide range of B. anthracis isolates to g phage as well as another phage specific for B. anthracis known as Cherry phage. We also compared susceptibility to phage with another detection method, susceptibility to …


The Development Of Molecular Diagnostics For Breast Cancer, Anna Henrik Israyelyan Jan 2003

The Development Of Molecular Diagnostics For Breast Cancer, Anna Henrik Israyelyan

LSU Master's Theses

Breast cancer is one of the most common malignancies in women. It continues to be a major burden and cause of death among women worldwide. Molecular oncology is now one of the most promising fields that may contribute considerably to diagnosis of breast cancer and its metastases addressing major problems with early detection, accurate staging, and monitoring of breast cancer patients. The overall objective of these feasibility studies was to contribute to improved diagnosis, prognosis, and prediction of breast cancer disease through the development of reagents and protocols for the use of molecular biological advances and the assessment of the …


Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary Jan 2003

Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary

LSU Master's Theses

Helicobacter hepaticus is well established as an unwanted variable in laboratory rodent colonies. Historically, caesarean section and embryo transfer have been used to derive Helicobacter-free mouse colonies. Neonatal transfer of newborn mice onto Helicobacter-free foster dams was recently reported as an alternative method of deriving Helicobacter-free mice, but until now, the age by which pups must be fostered to remain Helicobacter-free was unknown. The purpose of this study was to determine the age by which mouse pups must be fostered to remain H. hepaticus-free. Beginning on the day of birth, 20 C57BL/6 mice were fostered from H. hepaticus-positive parents onto …


The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich Jan 2003

The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich

LSU Master's Theses

Vaccination programs are designed to protect an animal from infection, however, depending upon the age and health of the animal vaccination may not stimulate a protective humoral response. It is possible that, as in the human and mouse models, geriatric equines may be less responsive than their younger counterparts to current vaccination protocols. The purpose of this study was to identify an age related diminution in the primary and secondary immune responses of geriatric horses in response to vaccination. Two groups of horses were sampled. The first group consisted of an open herd of 39 privately owned horses, varying in …
