Rapid detection of Mycobaterium ulcerans infection by recombinase polymerase amplification


This study is to explore the potential of using recombinase polymerase amplification (RPA) as a tool for Buruli ulcer diagnosis. RPA has emerged as a novel isothermal technology for use in molecular diagnosis of infectious diseases. This means that it can be carried out at room temperature in unsophisticated laboratories in West Africa close to patients. The key goal is to develop a diagnostic test for the early detection of Buruli ulcer in symptomatic patients with sufficient positive predictive value to put patients on appropriate treatment.
