All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Immunologic competence is correlated with resistance to infectious disease which may be affected by exposure to certain compounds. Methyl parathion (MP) and carbofuran (CF) have been reported to affect the development of active immunity in the rabbit and the present research was conducted to quantify the dosage relationships of these two pesticides to both host resistance and acquired resistance in the mouse.

Preliminary study was made on the virulence of Salmonella typhimurium in mice. Mortality rates among infected animals fed Purina Laboratory Chow diet providing 0.08, 0.7 3.0 mg MP/kg/day or 0.1, 0.6, 1.0 mg CF/kg/day along with untreated controls …
