G75-269 Calf Scours: Causes, Prevention And Treatment, Don Hudson, R. Gene White

University of Nebraska-Lincoln Extension: Historical Materials

Calf scours or calf diarrhea: understand how to recognize and treat this costly condition. Calf scours or calf diarrhea causes more financial loss to cow-calf producers than any other disease-related problem they encounter. Calf scours is not a disease--it is a clinical sign of a disease which can have many causes. In diarrheas, the intestine fails to absorb fluids and/or secretion into the intestine is increased.

Virus Diseases In Agriculture, George Mclean

Journal of the Department of Agriculture, Western Australia, Series 4

Viruses are extremely small particles which can only be seen with an electron microscope. A virus is present in a diseased plant as huge numbers of tiny particles within the cells of the plant. Viruses which are infectious can cause disease, and reproduce only inside the cells of a living plant.

Many insects transmit plant virus diseases—aphids, leafhoppers, mealy bugs, thrips and beetles. Generally a virus is spread by only one of these groups of insects.

The Western Australian Department of Agriculture is expanding the diagnostic service for the identification of plant viruses.

The Sheep Measles Control Programme, J B. White

Journal of the Department of Agriculture, Western Australia, Series 4

In the first seven months of 1968 Australia exported to the United States 17 747 tons of boned mutton; of this 2 198 tons, or 12.4 per cent, was condemned on arrival in that country.

The main cause of rejection was the presence of Cystkercus ovis cysts, the intermediate stage of the tapeworm Taenia ovis, of which the definitive host is the dog.

In 1969 the Western Australian Department of Agriculture decided to study the epidemiology of this disease.

This was the beginning of the work which would evolve into the 'Three Shire Control Programme'

Integrated Numerical Simulation Of Drip Irrigation With Subsurface Drainage, James Ray Hoover

Electronic Theses and Dissertations

A numerical method and model were developed to simulate soil moisture during steady-state and transient flow toward a tile drain. Intermittent application of water by drip irrigation and rainfall were simulated by use of finite difference approximation equations. No known analytical solution for these flow situations exists because of the complex mathematics describing unsaturated flow in the soil. The computer model is based on the electrical resistance network analog. The explicit finite difference equations were solved by the successive over-relaxation method for steady-state flow and by iteration for transient soil moisture flow. The computer program for the model consists of …

Pesticide Residues In The Illinois Wild Turkey, John M. Bridges

Masters Theses

Adipose tissue from 55 turkeys, killed during the 1974 hunting season in southern Illinois, was grouped by age and location of the birds, and the pesticide concentrations in them were determined by gas/liquid chromatography. Twelve different pesticides were identified in the samples with only four, total DDT, heptachlor epoxide, toxaphene, and linuron, being present in all samples. Concentrations ranged from 0.02 ppm to 0.88 ppm.

The Thiourea Carrier In Human Erythrocytes, Beny Leon Rozenbaum

University of the Pacific Theses and Dissertations

The main purpose of this work is to determine the characteristics of the thiourea carrier in human erythrocytes taking into consideration the two parameters of transfer (half-saturation constant and maximum transport rate) and the energy of dissociation of the carrier complex. In the president experiment, the problem has been approached by observing the exit of thiourea, from cells previously equilibrated with thiourea, into a saline medium containing different concentrations of thiourea. The most important advantages of this method are the rapidity of the exit process and the fact that it can be easily measured.

Numerical Taxonomy Of Anaerobic Bacteria Isolated From Ground Water Of A Sanitary Landfill, Kenneth J. Curry

Retrospective Theses and Dissertations

Section I: Facultative and obligatory anaerobic bacteria were isolated from the ground water of a sanitary landfill characterized by sandy soil and a periodically high water table. Isolates were examined for 63 characteristics and subject to numerical analysis. Eight clusters were established and correlations with conventional taxonomy were made. The Bacteriodaceae were found to be the dominant group of organisms by the methods employed. The anaerobic population was observed to decrease as the period of seasonal rainfall ended. At the same time, gram positive anaerobes were largely replaced with gram negative ones. Leaching between sampling sites (wells) made correlations between …

Antibiogram Patterns Of Primary Isolates Of Staphylococcus Aureus In Relation To Enzymatic Activity And Phage Type, John Kevin Hall

University of the Pacific Theses and Dissertations

The genus Staphylococcus is a member of the family Micrococcaceae which includes three other general Micrococcus, Planococcus and Aerococcus. The four which have the same morphology and gram reaction may be distinguished from each other on the basis of arrangement, the utilization of glucose, the presence or abscence of cytochromes, oxygen requirements, motility and the G + C content of DNA. (Table I), The genus Staphylococcus includes three species; S. aureus, S. epidermidis and S. saprophyticus. These may be distinguished from each other on the basis of coagulase production, mannitol utilization, production of alpha toxin, presence of heat resistant endonucleases, …

Characterization Of Radiation-Resistant Vegetative Bacteria In Beef, Ardyce Welch, R. B. Maxcy

Department of Food Science and Technology: Faculty Publications

Ground beef contains numerous microorganisms of various types. The commonly recognized bacteria are associated with current problems of spoilage. Irradiation, however, contributes a new factor through selective destruction of the microflora. The residual microorganisms surviving a nonsterilizing dose are predominantly gram-negative coccobacilli. Various classifications have been given, e.g., Moraxella, Acinetobacter, Achromobacter, etc. For a more detailed study of these radiation-resistant bacteria occurring in ground beef, an enrichment procedure was used for isolation. By means of morphological and biochemical tests, most of the isolates were found to be Moraxella, based on current classifications. The range of growth temperatures was …

Reuse Limits And Regeneration Of Solutions For Cleaning Dairy Equipment, S. M. Kulkarni, R. G. Arnold, R. B. Maxcy

Department of Food Science and Technology: Faculty Publications

Usable life of cleaning solutions in a model heat processing unit was studied by evaluation of the nature and quantity of residue remaining on the surface of the equipment after cleaning. Lipoidal residue was recovered from equipment surfaces by ether rinsing. A surface displacement technique was used to quantify the lipoidal material, which was characterized by gas-liquid chromatographic analyses of triglycerides and fatty acid methyl esters. Effects of factors, such as water hardness, rinse water temperature, cleaning solution additives and acid versus alkaline cleaners also were investigated in relation to overall cleaning efficiency. After evaluating limits of reuse of cleaning …

Distribution And Effects Of Bacterial Endotoxin, Anne Carter Adams

Theses and Dissertations

In this study the distribution and effects of bacterial endotoxin were examined. Adult male BALB/c and adult male DUB/ICR mice were used in all experiments. Endotoxic activity of a number of strains from three genera of bacteria, Pseudomonas, Bacteroides, and Listeria, was detected using vincristine-treated mice as sensitized indicators for endotoxin and resistance to purified endotoxin induced by pretreatment with selected bacteria. Also, the effect of bacterial endotoxin and endotoxin-like substances on the course of primary amebic meningoencephalitis in mice, caused by Naegleria fowleri, was assessed.

Solubilization Of Acetylcholinestrerae From Subcellular Components Of Mammalian Brain Tissue, John E. Taylor

University of the Pacific Theses and Dissertations

Since all chemical and electrical input into the cell / occurs via its plasma membrane, many pharmacological agents and hormones initiate their effects by interacting with receptor sites on the plasma membrane or by passing through the cell membrane and interacting with other membranes within the cell. Generally, the precise mechanisms by which these events occur remain relatively unclear. It was thought for many years that the cell membrane was a relatively static structure which allowed molecules to enter the cell at a rate dependent upon their degree of lipid solubility. However, more recently an increasing body of evidence suggests …

Osteology Of Trypauchenichthys Sumatrensis Hardenburg, Christine Parrish Baer

Biological Sciences Theses & Dissertations

The osteology of a Malaysian goby was examined in detail and compared to other gobioids. Results indicated that Trypauaheniahthys sumatrensis is a specialized, but definite member of the Gobioidei. Some osteological characteristics of a related fish, Trypauchen vagina, were also discussed.

Sclerosing Cholangitis: Surgical Significance, C. Grodsinsky, M. A. Block, B. E. Brush

Henry Ford Hospital Medical Journal

The authors' experience with the rare entity of sclerosing cholangitis suggests that several anatomical patterns of involvement of the extrahepatic biliary tract may occur. The involvement may include the intraluminal ducts segmentally or diffusely, or the process may primarily be external to the ducts as pericholedochitis. It may or may not represent one component of a systemic disease, particulady autoimmune disease. Although involvement may be diffuse, progression may be slow and compatible with many years of life. Long time followup is essential before any value can be assigned to a given modality of treatment. Carcinoma of the ductal system may …

Left Atrial Myxoma With An Atrial Septal Defect: Report Of A Case, Daniel T. Anbe, Edward Arciniegas, Henry Green, Ellet H. Drake

Henry Ford Hospital Medical Journal

A case of a left atrial myxoma presented unusual features including (1) association with an atrial septal defect, (2) attachment of the myxoma to the posterior wall of the left atrium, (3) probable paradoxical pulmonary embolization from the left atrium, and (4) probable ball valve effect of the myxoma in the atrial septal defect.

A Study Of Naturally Occurring Algicides Produced By Freshwater Algae, Denny O. Harris, Harry D. Caldwell

KWRRI Research Reports

The mode of action of the algicide produced by Pandorina morum was examined by exposing Volvox globator and isolates spinach chloroplasts to a partially purified algicide preparation. Oxygen evolution of Volvox, whole chloroplasts and broken chloroplasts (minus the Calvin cycle),was reduced indicating that the algicide inhibits the light reactions of photosynthesis. Oxygen evolution studies of other Volvocaceae confirmed the observation that Pandorina morum is not significantly influenced by its own inhibitor. Molecular weight approximation by gel filtration established that the inhibitor has a low molecular weight (probably below 100 mw). Field studies indicate that this algicide has tremendous potential as …
