Zombie Fungus

Scientists have discovered the existence of 4 separate species of what is coined “zombie fungus” in rainforests in Brazil.

This zombie fungus overhauls the brains of the ants it uses as its host, and controls them in such a way as to force them to leave their colonies, and to relocate somewhere that is better suited for the fungus to survive before the fungus actually kills them.

The scientific journal, Plos ONE, published a study on March 2nd, 2011, in which scientific researchers from Brazil, the USA & the UK explain they started investigating after discovering dead carpenter ants with fungus growing out of their bodies.

In the study, the researchers state:

“This so-called zombie or brain-manipulating fungus alters the behaviour of the ant host, causing it to die in an exposed position, typically clinging onto and biting into the adaxial surface of shrub leaves.”

What happens next? Well, the fungus grows out of the ants body, typically via the head and neck area, to release the spores needed for the next generation of fungus to proliferate.

The organism’s scientific or Latin name is Ophiocordyceps, and it was thought there was only one species of such fungi. However, upon investigation, it’s been ascertained that there are, in fact, four of these fungi species.

Leader of this study, David Hughes, who is also an entomologist at Penn State University shared with National Geographic:

“It is tempting to speculate that each species of fungus has its own ant species that it is best adapted to attack…This potentially means thousands of zombie fungi in tropical forests across the globe await discovery…We need to ramp up sampling – especially given the perilous state of the environment.”
