Description

In Spring 2021, five members of the student organization Flyers Against Antibiotic Resistance performed a surveillance project in collaboration with students in the BIO 411L General Microbiology Lab course to investigate the prevalence of antibiotic resistance around the University of Dayton campus. We tested bacterial isolates collected from soil by the BIO 411L students and from human-associated surfaces for their growth on tetracycline-containing agar plates where a positive growth would indicate tetracycline resistance. We found that the prevalence of tetracycline-resistant bacteria was much higher in isolates from human-associated surfaces than isolates from soil. The 4 different media types also contributed differently to the isolation of tetracycline-resistant bacteria. Moreover, stairs and floor surfaces account for the majority (31% and 29.4%, respectively) of resistant isolates from human-associated surfaces. In summary, tetracycline resistance is present in a variety of environments and can potentially be spread from human-environment interactions.
