Sea slug mixes chemical defense before firing at predators

a predators which are affected by this property of the secretion.

"The antimicrobial property probably evolved to work against predators," said Derby. "But it might also function as an antimicrobial salve for Aplysia's own wounds."

Derby's team, who discovered escapin and holds a provisional patent for its genetic sequence, has been studying the protein for its potential applications as an antimicrobial compound for the healthcare and marine industries. The team has determined that escapin prevents the growth of all major forms of bacteria as well as other microbes.

"As we learn more about how escapin works in Aplysia, we will hopefully be able to reproduce its chemical properties in the laboratory," said Derby.

In addition to Derby, co-authors of the Journal of Experimental Biology study are Paul Johnson, PhD, Cynthia Kicklighter, PhD, Manfred Schmidt, PhD, Michiya Kamio, PhD, Hsiuchin Yang, PhD, and Phang Tai, PhD, of the Georgia State biology department. Other co-authors include physiologists Dimitry Elkin and William Michel, PhD, of the University of Utah School of Medicine.
