Detection of carbapenemases in Enterobacterales and other Gram-negative bacilli recovered from hospital and municipal wastewater in Mexico City

The study found that wastewater contains carbapenem-resistant and carbapenemase-producing Gram-negative bacilli (GNB), with Enterobacterales being the most common group. The study also identified a high-risk clone in municipal wastewater, highlighting the need for epidemiological surveillance to address the public health threat posed by these bacteria.
