Identification Of Antibiotic Ge37468a From Pseudonocardia Symbionts Of Trachymyrmex Septentrionalis Ants, Krithika Rao

Scripps Senior Theses

In response to the growing rates of antibiotic resistance in human bacterial pathogens, this study explores the natural products involved in the defensive symbiosis between actinobacteria and fungus-growing ants to uncover new potential antibiotics. This study also seeks to understand the function of natural antibiotics in their ecological contexts, especially those involved in defensive symbioses. Defensive symbiosis can be a beneficial platform for discovering useful antibiotics, because antibiotics in these relationships must be able to selectively inhibit enemies without harming hosts, and are therefore likely more specific and less toxic. Pseudonocardia sp. associated with Trachymyrmex septentrionalis ants demonstrated antibiotic activity …
