A Novel Strategy Of Controlling Bovine Pneumonic Pasteurellosis: Transfecting The Upper Respiratory Tract Of Cattle With A Gene Coding For The Antimicrobial Peptide Cecropin B, Charles Mitchell Boudreaux
A Novel Strategy Of Controlling Bovine Pneumonic Pasteurellosis: Transfecting The Upper Respiratory Tract Of Cattle With A Gene Coding For The Antimicrobial Peptide Cecropin B, Charles Mitchell Boudreaux
LSU Master's Theses
The very potent antibacterial activity of cecropin B makes it a likely candidate to prevent and/or treat Mannheimia haemolytica 1:A infection in the upper respiratory tract (URT) of cattle. The purpose of this study was to ascertain if the URT could be transfected with a gene coding for the antimicrobial peptide cecropin B. By transfecting cattle with a gene coding for cecropin B, this study attempted to inhibit colonization of a virulent strain of M. haemolytica 1:A in the URT while investigating any possible changes in the indigenous and transient nasal flora. In this study the antibacterial efficacy of cecropin …
Early Tissue Migration Of And Host Response To Brugia Pahangi In Gerbils, Kristina Houpe Porthouse
Early Tissue Migration Of And Host Response To Brugia Pahangi In Gerbils, Kristina Houpe Porthouse
LSU Master's Theses
The host-parasite interaction during early filarial nematode migration is poorly understood. The objective of this study was to develop a model of early cutaneous filarid migration using Brugia pahangi in the jird (gerbil) host and measure the histologic and cytokine responses during this period. Male gerbils were intradermally inoculated in the left hindlimb with 100 B. pahangi L3 then necropsied at 3 hours, 24 hours, 3 days, 7 days, and 28 days post-infection. Larvae were recovered and tissues collected for histology and cytokine measurement. At 3 hours, most larvae (96.3%) were recovered from tissues associated with the infection site. Migration …
Methods To Induce Earlier Onset Of Cyclicity In Transitional Mares, Abdulhakeem Hashim Aljarrah
Methods To Induce Earlier Onset Of Cyclicity In Transitional Mares, Abdulhakeem Hashim Aljarrah
LSU Master's Theses
The purpose of this study was to investigate methods to induce earlier onset of cyclicity in transitional mares. Two experiments were conducted evaluating the effect of follicular aspiration to advance the onset of cyclicity, more succinctly define criteria for selection of mares for follicular aspiration and to compare aspiration to deslorelin treatment for initiating cyclicity in transitional mares. In Experiment 1, anestrous mares were assigned to control (n=6) or follicular aspiration (n=11). The control mares were monitored twice weekly, until ovulation was detected. The aspiration mares were similarly monitored until a follicle >35 mm was identified, then transvaginal ultrasound guided …
The Effectiveness Of Language-Literacy Training For Child Care Workers, Katelyn Beth Venturella
The Effectiveness Of Language-Literacy Training For Child Care Workers, Katelyn Beth Venturella
LSU Master's Theses
The purpose of the current study was to examine the effectiveness of group-based language-literacy training for child care workers. The first phase of the study followed a pre-post single group comparison design and involved 23 child care providers. The independent variable was the teacher training and the dependant variable was scores from a questionnaire. The second phase of the study involved a sub-group of four child care workers who received one-on-one follow up training after the group sessions. The questionnaire was administered a third time to the follow-up group. An analysis of the questionnaire items at pretest indicated that the …
Improved Methods For The Isolation And Characterization Of Flavobacterium Columnare, Bradley Donovan Farmer
Improved Methods For The Isolation And Characterization Of Flavobacterium Columnare, Bradley Donovan Farmer
LSU Master's Theses
Columnaris disease, caused by the bacterium Flavobacterium columnare, is an economically significant problem in many warmwater fish species. Difficulties encountered in the isolation and culture of F. columnare have been an impediment to research on the organism and the disease it causes. The goal of this study was to improve the methods for isolation, culture, identification and maintenance of F. columnare. Following the evaluation of different culture media selective cytophaga agar was determined to be the optimum isolation medium, Flavobacterum columnare growth medium proved to be the optimum culture medium, and tryptone yeast extract agar with increased moisture was best …
Evaluation Of Rough Brucella Strains As Vaccines For Brucellosis And Pseudorabies In Swine, Lorraine Harrow Molin
Evaluation Of Rough Brucella Strains As Vaccines For Brucellosis And Pseudorabies In Swine, Lorraine Harrow Molin
LSU Master's Theses
Brucellosis and pseudorabies lead to abortion in pregnant sows and are perpetuated by feral swine reservoirs. A multivalent oral vaccine for these diseases would improve vaccination and eradication programs worldwide. Previous studies have shown that the rough attenuated Brucella strains RB51 and VTRS1, when administered subcutaneously to swine, stimulate host immune responses, transiently colonize tissues, and provide partial protection against virulent B. suis infection in pregnant sows. A plasmid encoding for the pseudorabies virus glycoprotein D (PRV gD) has also been added to these strains as part of this project. This study evaluates the use of these strains as oral …
In Vitro Evaluation Of The Securos Cranial Cruciate Ligament Repair System And Fluorocarbon Leader Line For Use As Lateral Fabella-Tibial Sutures, Max Nielsen Banwell
In Vitro Evaluation Of The Securos Cranial Cruciate Ligament Repair System And Fluorocarbon Leader Line For Use As Lateral Fabella-Tibial Sutures, Max Nielsen Banwell
LSU Master's Theses
Cranial cruciate ligament (CCL) rupture is a common injury in the dog and major cause of degenerative joint disease. The pathophysiology of CCL rupture in the dog is well described. Osteoarthritis secondary to CCL rupture causes severe pain and lameness. There are many surgical techniques accepted for dogs with CCL rupture. A commonly performed technique is an extracapsular repair with a lateral fabella-tibial suture (LFS) using large diameter nylon leader line (NLL). Mechanical demands placed upon the LFS are high requiring the material used be able to withstand a high amount of force, undergo minimal elongation, and have a high …
Louisiana State University Nasalance Protocol Standardization, Kathryn Ruth Kendrick
Louisiana State University Nasalance Protocol Standardization, Kathryn Ruth Kendrick
LSU Master's Theses
It was the purpose of this study to obtain nasalance values using the Nasometer and a resonance evaluation created at the Louisiana State University (LSU) Speech and Hearing Clinic. The Nasometer was used to measure the amount of nasal acoustic energy in the speech of 40 normal young adults during sustained vowel production, consonant vowel reduplications, and connected speech using the Rainbow Passage. Means and standard deviations are presented for the individual speech tasks and according to gender. Nasalance values for the sustained vowels were significantly higher for the high front vowel /i/ than any other vowel, and the lowest …
The Effects Of Non-Focused Extracorporeal Shock Waves On Neuronal Morphology, Function And Analgesia In Horses, David Manuel Bolt
The Effects Of Non-Focused Extracorporeal Shock Waves On Neuronal Morphology, Function And Analgesia In Horses, David Manuel Bolt
LSU Master's Theses
These studies were conducted to elucidate the regional analgesic effect that is observed clinically after treatment of orthopedic disorders with application of extracorporeal shock waves in horses. Regional analgesia after treatment with extracorporeal shock waves presents a concern because it may eliminate protective limiting mechanisms and may place equine athletes with predisposing lesions at risk of sustaining career- or life-ending injuries. Direct percutaneous application of non-focused extracorporeal shock waves to palmar digital nerves in the pastern area of horses resulted in decreased sensory nerve conduction velocities compared with untreated control nerves at 3, 7, and 35 days after treatment. Transmission …
