Cover Story: Bacterial discrimination at the ‘species’ and ‘strain’ levels using host responses remains elusive. This research aimed to investigate the proof of concept that bacterial ex vivo whole blood responses can provide sufficient data to discriminate bacteria. The pairwise analysis of immune responses allowed for the development of a scheme for bacterial discrimination at the strain level, with threshold values providing decisions to ‘turn left or right’ to identify bacteria. The accuracy of linear discriminant analysis increased in the following order: strain (40%) → species (90%) → genera (95%). Therefore, host responses in the ex vivo whole blood model can be used to discriminate bacteria, paving the way for biomarker development. View this paper
