Actinomycetes are able to utilize a great variety of carbohydrates, like sugar. The particular kind of sugar and its concentration has decisive effect on the growth of microorganisms. The proper nutritional media aids also in the production of spores. Based on this generalization, that the growth and sporulation of microorganisms are greatly influenced by the nature and the concentration of carbohydrates, an attempt has been made to study Actinoplanes philippinensis with respect to this influence.

The purpose of this investigation was to analyze the distribution of amphibians and reptiles in Texas by means of the methods of Webb and Hagmeier and Stults. An additional graphical analysis was made, including range and range limits which provides a cross-section of faunal change along selected base lines across the state.

This particular work is proposed as a test of the expedience of using the fluorescent-antibody technique as a method for enumeration and identification of certain strains of B. cereus that have been found to be effective in preventing taste and odor in water supplies resulting from certain Actinomycete blooms.

It was the purpose of this investigation to present laboratory data concerning the assimilation of inorganic nitrogen by the aquatic actinomycetes. The strains of aquatic actinomycetes under consideration represented a cross section of those currently under culture at North Texas State University.

There were two purposes of this investigation: the first was to develop a method for studying spore germination, hyphal growth and mycelial development of the aquatic actinomycetes under the microscope so that the life cycle of this organism could be continuously followed. The second purpose was to determine the rate of carbon utilization from various types of nutritional sources, and to correlate this with the colony development and spore formation.

The purpose of this investigation is to determine if auto-antibodies are demonstrable in inflammatory periodontal disease using methods other than those of Novotny.

The purpose of this investigation is to attempt to learn something of the biochemical ecology of volatile substances produced by actinomycetes.

In this study organisms that can be subcultured from lake water, using a prescribed procedure, limit, to an extent, the population, or portions of the population, that can be monitored. In essence, what is taking place is that a set of conditions is set forth and a study is made of the bacteria that will grow under these prescribed conditions.

The purpose of this investigation was to characterize the population dynamics of the benthos of selected pristine thermal springs.

The purpose of this investigation was to study the effects of decreased barometric pressure on the transcapillary movement of molecules by monitoring the macromolecular capillary permeability with lymph derived primarily from the hepatic and gastrointestinal regions of the dog.

It was the purpose of the present investigation to demonstrate the selection of a variant of one strain of Staphylococcus aureus by altering certain environmental factors, and to study that variant as to biochemical activities and capsule formation.

This thesis compares the specificity of passive transfer of chemical contact hypersensitivity following various methods of sensitization.

The purpose of this study was to demonstrate the variability of oxygen and carbon dioxide rate of change methods for measuring primary productivity and respiration in an aquatic environment.

This paper will attempt to determine whether the increased C'4 previously shown following antigen and adjuvant injection could be correlated to antibody increase following antigen injection.

The present study was concerned with the testing of antigenic material derived from a number of streptomycetes in an effort to establish an auxiliary taxonomic scheme based upon cytoplasmic antigen relationships among these organisms.

This study was designed to show what dissemules may be carried by selected genera of Odonata, where the dissemules may be predominantly carried on the selected insects and to relate the behavior of the selected Odonata to frequency of occurrence of micro-organisms on the insects.

The purpose of this paper is to detail the distribution and quantity of soluble phosphates in an activated sludge plant, its discharge creek, and receiving reservoir. The resultant analyses and comparison of data should provide some better understanding of the fate of phosphorus in a Southwestern waterway system.

The purpose of this study was to make a preliminary study of the herpetofauna of Montague County in relation to ecological distribution. Also taken into consideration were the zoogeographic relationships of the various species.

The purpose of this research was to compile a presence list of reptiles and amphibians that occur in Palo Pinto County, Texas, and to investigate the ecological distributions and zoogeographic affinities of these herpetiles. The study area was chosen primarily because of its location in North Central Texas and its rugged topography, which sets it apart from the surrounding area.

This investigation was undertaken to explore biochemical changes which may occur in heart tissue with age. In this connection, the cellular enzymes were of special interest.

The current work was undertaken to test the ability of avidin to affect the course of leukemia when administered intraperitoneally.

The major purpose of this investigation was to determine the effect of carbon monoxide on the development of various morphological phases of a single isolate of the aquatic streptomycetes and to elucidate the physiological differences between terminal respiration in the primary and secondary stages. A secondary purpose was to repeat the work of Michael Lee Higgins involving the effect of anaerobiosis on the growth of the organism.

In this study the effects of repeated antigen injections on total complement (C') and C'4 of guinea pig serum were investigated to determine if constant antigenic stimulation would show changes in the C' and C'4 titers. Attempts were also made to correlate any changes with variations in antibody titers during the repeated antigen injections.

This thesis investigates immobilization and its complications in dogs.
