Newsweek features studentā€™s discovery of ā€˜zombie fungusā€™

Published

A University of Ā鶹¹ū¶³“«Ć½ at Lafayette student has discovered a ā€œzombie fungusā€ thatā€™s been off scientistsā€™ radar for almost a century, reports this week.

Stephen Saltamachia, a senior majoring in microbiology at Ā鶹¹ū¶³“«Ć½ Lafayette, discovered the rare, furry fungus while working at Acadiana Park Nature Station in Lafayette. He spotted a carpenter ant queen wandering outside, which caught his attention since a queen rarely leaves her nest.

ā€œA born naturalist, Saltamachia suspected that the ant might be parasitized by a brain-manipulating pathogen often called 'zombie fungus,' which causes infected insects to behave abnormally,ā€ an article posted on Newsweekā€™s website late Monday states.

Saltmachia studied the errant ant after sterilizing it and placing it in a petri dish.

ā€œThe dead insect gave rise to a vigorous, furry fungus that sprouted from its dead body like moldering cotton candy,ā€  Douglas Main writes in the .

The magazine cites David Hughes, a researcher at Pennsylvania State University who specializes in zombie ant fungi. He said the fungi had been ā€œ ā€˜missed by mycologists and entomologistsā€™ ā€ for almost 100 years. The last time it was mentioned as a major citation in studies was in the 1920s, according to Newsweek.

Why is it called a ā€œzombie fungusā€?

ā€œFungi in this group infects ants and other insects and often control their behavior to maximize their potential to spreadā€”before ultimately killing the animal. For example, one such fungus infects ants and forces them to climb high up vegetation before perishing and giving rise to horn-like fungal growths, thus allowing the speciesā€™s spores to spread farther than they would if released closer to the ground,ā€ Main explains.
