Observing The Effects Of Antimalarial Drug Availability On Women’S Work Absenteeism, Rei Imada

CMC Senior Theses

This study aims to provide insight on how availability of antimalarial drugs can help alleviate the economic burden of malaria. Much of the existing literature that looks into the effects of antimalarial drug availability focuses on the associated health benefits, but fails to draw a link to the economic benefits that may also be incurred. Using data from the 2015-2016 Tanzania Demographic and Health Survey and Malaria Indicator Survey, this study performs a series of multiple regressions to observe how increased availability of artemisinin-based combination therapies (ACTs), a front-line antimalarial drug in most African countries, affects likelihood of work absenteeism …

Antifungal Defense Molecules From Bacterial Symbionts Of North American Trachymyrmex Ants, Georgia Scherer

CMC Senior Theses

Defensive symbioses, in which microbes provide molecular defenses for an animal host, hold great potential as untapped sources of therapeutically useful antibiotics. Fungus-growing ants use antifungal defenses from bacterial symbionts to suppress pathogenic fungi in their nests. Preliminary chemical investigations of symbiotic bacteria from this large family of ants have uncovered novel antifungal molecules with therapeutic potential, such as dentigerumycin and selvamicin.

In this study, the bacterial symbionts of North American Trachymyrmex fungus-growing ants are investigated for antifungal molecules. Plate-based bioassays using ecologically-relevant fungal pathogens confirmed that these bacteria have antifungal activity. In order to purify and identify the antifungal …
