TRAINAU is a multidisciplinary early-stage training programme on identification, characterisation, and assessment of public health risks associated with non-human use of antimicrobials The development of human resources capable to carry out this task requires multidisciplinary training. Accordingly, TRAINAU is bringing together early-stage researchers with different backgrounds and providing them the scientific and technological competences necessary to perform research and obtain substantial progress in this field. Descriptive and analytical epidemiological studies will investigate the association between different antimicrobial usage patterns and occurrence of antimicrobial resistance in animals. Experimental research will include laboratory experiments to validate results from field studies and to provide quantitative data to be used by the risk assessment. The multidisciplinary approach of TRAINAU is expected to generate new information needed for assessment of risks to public health associated with non-human use of antimicrobials.
