Understanding and modelling reservoirs, vehicles and transmission of ESBL-producing Enterobacteriaceae in the community and long term care facilities (MODERN)

Environment

Transmission

MODERN is an international collaborative project investigating the reservoirs and transmission of Enterobacteriaceae producing extended-spectrum β-lactamases, a group of antibiotic-resistant bacteria that has spread worldwide recently.

Ongoing project

The study is centered in transmission in non-hospital environment such as households and nursing homes, and include food products, environmental reservoirs and wastewater. Advanced epidemiological methods and whole genome sequencing are being used to identify the rate and risk factors for transmission of these bacteria among residents in these environments in order to produce the information needed to build mathematical models explaining their spread, which will allow to estimate the impact of potential control measures.

Very exhaustive and state-of-the-art studies have been carried out to see the characteristics of these bacteria and their way of transmission, which is different in different species. Knowing this, and adding all the demographic characteristics and risk factors collected from each participant, using advanced mathematical methodology, a model is developed that allows predicting transmission. The ultimate goal is to be able to act at critical points in order to end the problem of antibiotic resistance.
