Imaging Amphotericin B orientation in Candida spp. through polarization stimulated Raman scattering microscopy (Conference Presentation)

Paper Abstract

Candidemia remains the fourth most common cause of nosocomial bloodstream infections. For more than a half-century, amphotericin B (Amp B) has been the last line of defense in the treatment of life-threatening fungal infections. However, during the past several years, severe infections due to Amp B-resistant Candida spp. isolates have been increasingly reported. Here, through polarization stimulated Raman scattering microscopy, Amp B was found to accumulate largely in the cell membrane of Candida spp. in a highly orientated approach, and the interaction between Amp B and ergosterol was investigated as well. Moreover, we found that the correlation between Amp B and ergosterol in Amp B-susceptible Candida spp. is different from that of Amp B-resistant Candida spp., which provides us important information to understand the working mechanism of Amp B, and to achieve fast determination of the Amp B susceptibility of Candida spp.
