Resistance of Some Soil Bacteria to Pentachlorophenol and Sodium Pentachlorophenate

Resistance of Some Soil Bacteria to Pentachlorophenol and Sodium Pentachlorophenate

Date: August 1970
Creator: Ferguson, Patricia Kaspar
Description: The purpose of this study was to see if any soil bacteria were able to use pentachlorophenol or sodium pentachlorophenate either aerobically or anaerobically as a sole carbon source, to see if any soil bacteria could survive in high concentrations of sodium pentachlorophenate, to determine the maximum concentration of sodium pentachlorophenate which permitted the growth of some soil bacteria, to see the effects of varying concentrations of sodium pentachlorophenate on the growth curves of soil bacteria capable of growing in its presence, and to see if any soil bacteria could degrade sodium pentachlorophenate.

Factors Involved in the Antibiotic Sensitivity of Staphylococcus Aureus

Factors Involved in the Antibiotic Sensitivity of Staphylococcus Aureus

Date: June 1961
Creator: Rotter, Joan
Description: It was the purpose of the present investigation to determine if sensitivity to other antibiotics can likewise be affected by subjecting S. aureus to heparin contact. It is of special interest in this problem to determine whether heparin in some manner affects the combining process of penicillin with the cells of several strains of S. aureus.

Morphological and Physiological Changes in Micrococcus Pyogenes Var. Aureus during Development of its Resistance to Terramycin

Morphological and Physiological Changes in Micrococcus Pyogenes Var. Aureus during Development of its Resistance to Terramycin

Date: August 1959
Creator: Watson, Gerald T.
Description: The problem in this investigation consists of, first, the procurement of several strains of Micrococcus pyogenes var. aureus; second, the comparison of the degree and rate of development of resistance of these organisms to terramycin; and, third, to study the morphological and physiological changes which occur during the development of resistance.

Naphthoquinone Studies

Naphthoquinone Studies

Date: 1955
Creator: Padgett, William A.
Description: This thesis describes a series of naphthoquinone reactions employing pyridine carboxylic acid derivatives (nicotinic acid derivatives). The products of these reactions will be tested by Parke, Davis and Company for their activity against the tubercle bacillus and other pathogenic microorganisms.

The Effects of Heparin on the Development of Resistance to Antibiotics by Staphylococcus Aureus

The Effects of Heparin on the Development of Resistance to Antibiotics by Staphylococcus Aureus

Date: August 1959
Creator: Blanton, William George
Description: Since heparin combines with some antibiotics to decrease the toxicity of the antibiotic to the patien, the purpose of this investigation is to determine whether it has any effect upon the development of resistance to antibiotics by Staphylococcus aureus.

Preparation of Pyridinium Derivatives of 2,3-Dichloro-5(8?)-Nitro-1,4-Naphthoquinone

Preparation of Pyridinium Derivatives of 2,3-Dichloro-5(8?)-Nitro-1,4-Naphthoquinone

Date: 1955
Creator: Mahon, Frank
Description: This paper describes the preparation of pyridine derivatives of 2,3-dichloro-5(8?)-nitro-1,4-naphthoquinone. A method for the nitration of 2,3-dichloro-1,4-naphthoquinone is also described. Certain 4-n-alkyl, 3,4-dialkyl, and 4-cycloalkyl pyridine derivatives are caused to undergo condensation reactions with the nitrated naphthoquinone, giving rise to a series of compounds of the preceding type (X). All of the compounds prepared will be tested for anti-tubercular activity by Parke-Davis and Company.

The Antibiotic Activities of Some Members of the Cactaceae Family

The Antibiotic Activities of Some Members of the Cactaceae Family

Date: 1951
Creator: Gilmore, Derward E.
Description: This problem has been concerned with, first, the collection of sixteen species of plants belonging to Cactaceae family; second, the drying of these and the extraction of the oleoresins thereof; third, the determination of the extent to which these substances inhibit the growth of ten gram-positive and ten gram-negative bacterial organisms; and fourth, a determination of the possible utilization of these extracts a prophylactic or chemotherapeutic agents.

Chemical and Physiological Properties of an Antibiotic Produced by a Variant of the Penicillium Notatum-Chrysogenum Group

Chemical and Physiological Properties of an Antibiotic Produced by a Variant of the Penicillium Notatum-Chrysogenum Group

Date: 1947
Creator: Conyers, Loyd, W.
Description: The present study of the production and properties of an antibiotic was undertaken in the hope that some useful information could be contributed to a long-range investigation program being carried on at North Texas State Teachers College. This program is concerned with the production of a useful antibiotic from a variant of the Penicillium notatum-chysogenum group of molds.

The Inhibition of Fungal Contaminants in Cultures of Mycobacterium Tuberculosis

The Inhibition of Fungal Contaminants in Cultures of Mycobacterium Tuberculosis

Date: 1951
Creator: Wright, Noble M.
Description: The problem of conatmination in culture media for Mycobacterium tuberculosis has not been solved completely, and for this reason the work herein presented was carried out. In this work experiments were made testing the effect of actidione in inhibiting certain ones of the higher fungi.
