Dr Linda Stewart research focuses on the following;

(i) Development of rapid diagnostics for the detection of bacterial pathogens.Involves:biomarker discovery; binder generation, including polyclonal, monoclonal and recombinant antibodies, and peptide binders; binder characterisation and epitope mapping. Bacterial targets include Mycobacterium bovis, Mycobacterium tuberculosis, Mycobacterium avium subsp. paratuberculosis, Salmonella, Campylobacter, Escherichia coli Bacteroides fragilis. Detection platforms include lateral flow, biosensors, latex agglutination, ELISA, microfluidics, raman spectroscopy

(ii) The microbiome: specifically, Bacteroides fragilis and its role in health and disease.

(iii) Antimicrobial resistance and the discovery of novel antimicrobials
