The Antibiotic Resistance Action Center (ARAC) is a group of committed scientists, clinicians, communicators and policy experts working together to fight antibiotic resistance through cutting-edge research, science-based policy, evidence-based practice, and strategic communications. ARAC’s interdisciplinary team is navigating a world in transition to curb the threat of antibiotic resistance.


ARAC is part of the Milken Institute School of Public Health at the George Washington University. The center and its research lab are housed in GW’s newly opened Science and Engineering Hall -- an interdisciplinary research facility with state-of-the-art research space.

A Bit About Us
What is Antibiotic Resistance?

Antibiotics are our first line of defense against the bacteria that cause infections like strep throat and urinary tract infections. 


But bacteria can change over time and become “resistant” to certain antibiotics — meaning the antibiotics don’t work anymore. When this happens, it’s called antibiotic resistance.

How Does Antibiotic Resistance Occur?

High number of bacteria.

A few are resistant

to antibiotics

Antibiotics kill bacteria causing the illness as well as good bacteria protecting the body from illness.

The resistant bacteria now have preferred conditions to grow and take over

Bacteria can transfer their drug-resistance to other bacteria, causing more problems

What Causes Antibiotic Resistance?
Antibiotic resistance happens when bacteria change and become resistant to the antibiotics
