Ohio study links wastewater bacteria to chronic disease rates

Bacterial profiles reveal health patterns

The team evaluated bacteria found in the human gut within 27 wastewater samples. These samples came from nine treatment plants serving eight Ohio cities that housed more than 1.3 million people. The researchers compared their findings with public data on chronic diseases, health behaviors and demographics. They saw distinct bacterial profiles across the cities which highlighted significant differences in the community-wide gut-associated microbiome.

Specific bacteria linked to conditions

Various bacterial strains linked to community levels of obesity, hypertension, asthma, and additional chronic ailments were identified. Eight health outcomes, such as obesity and stroke, were linked to the presence of the bacterial group named Desulfovibrio. These bacteria were more prevalent in rural areas, and so were the incidence rates of various chronic illnesses.

Monitoring helps direct resources

Monitoring wastewater may enable public officials and policymakers to more accurately pinpoint communities confronting significant health issues. Such a method provides an exclusive means to assess community wellness beyond individual clinic patients. These results indicate that this method may provide a useful means to grasp wider health trends throughout various neighborhoods.
