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 …

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. …

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 …

Osmosensitive Taurine Release: Does Taurine Share The Same Efflux Pathway With Chloride And Other Amino Acid Osmolytes?, Rodrigo Franco Jan 2003

Osmosensitive Taurine Release: Does Taurine Share The Same Efflux Pathway With Chloride And Other Amino Acid Osmolytes?, Rodrigo Franco

School of Veterinary and Biomedical Sciences: Faculty Publications

Swelling subsequent to hyposmotic conditions activates a process of volume regulation present in most cell types. This volume adjustment is accomplished by osmolyte translocation toward the extracellular space to reach a new osmotic equilibrium. Molecules involved in this homeostatic mechanism have been broadly classified into two categories: organic and inorganic osmolytes. Inorganic osmolytes comprise mainly the intracellular ions K+ and Cl–. Cell swelling–induced activation of separate K+ and Cl– channels has been described in most preparations. Organic osmolytes are grouped in three categories: amino acids, polyalcohols, and methylamines. These osmolytes, particularly taurine, are present in …

The Effects Of Electrical Stimulation On The Sensory And Textural Quality Properties Of Mutton Carcasses, Mete Yanar, Hasan Yeti̇m

Turkish Journal of Veterinary & Animal Sciences

The objective of this research was to investigate the influence of electrical stimulation (ES) on the sensory and textural quality characteristics of mutton carcasses from elderly ewes. For this purpose, 14 ovine carcasses from 3-5-year-old ewes were subjected to ES with 350 V, and the effects of ES on the organoleptic and instron textural parameters were evaluated. The ES significantly (P < 0.01) improved the panel tenderness scores of the Longissimus dorsi (LD) muscle. Some of the Instron Warner Bratzler Shear parameters such as peak force and initial yield force values of the LD muscle were also highly significantly (P < 0.01) affected by ES, while the Semimembranosus (SM) muscle was not affected. Hardness and peak force 2 values of LD obtained from the Instron compression test were also significantly (P < 0.05) affected by ES. However, Instron compression parameters of SM muscles were not significantly influenced by ES treatment. The results revealed that the ES could considerably improve the tenderness of the LD from mutton carcasses. In conclusion, the application of ES to mutton carcasses from elderly ewes could be beneficial for the meat industry by increasing the merchandising value and quality of this sort of carcass.

Glycobiology Current Molecular Biology, Sabi̇re Karaçali

Turkish Journal of Veterinary & Animal Sciences

Carbohydrate chemistry evolved into carbohydrate biochemistry and gradually into the biology of carbohydrates, or glycobiology, at the end of the last century. Glycobiology is the new research area of modern molecular biology, and it investigates the structure, biosynthesis and biological functions of glycans. The numbers, linkage types (\alpha or \beta), positions, binding points and functional group differences of monosaccharides create microheterogeneity. Thus, numerous glycoforms with precise structural differences occur. Each glycoform as a distinct biological ligand has a different function. Studies in glycobiology have concentrated on determining molecular structures and glycosylation mechanisms, investigating biological control mechanisms and the phenotypic characteristics …
