An Environmental Engineering Approach to Regional One Health

One Health is a concept that views the health and well-being of humans, animals, and the environment as interconnected, promoting integrated conservation efforts. This approach has gained worldwide attention as a response to zoonotic diseases. Antibiotic-resistant bacteria pose a significant challenge, as infections caused by these resistant strains make treatment difficult, affecting both human and animal health. Recently, antibiotic-resistant bacteria have also begun to be detected in the environment, emphasizing the need for a One Health approach that goes beyond traditional disciplinary boundaries to address this issue.

In my laboratory, we conduct research using techniques such as genetic analysis to investigate the prevalence and spread of antibiotic-resistant bacteria in the environment. Recently, we have initiated a study on the prevalence and patterns of antibiotic-resistant bacteria found in wild animals living in river basin environments within the prefecture. By advancing this research, we aim to clarify the risks of transmission from the environment and wildlife to livestock and humans, ultimately contributing to regional One Health efforts.
