Abstract: The dissemination of the virulent pathogen 'Batrachochytrium dendrobatidis' ('Bd') has contributed to the decline and extinction of many amphibian species worldwide. Several different strains have been identified, some of which are sympatric. Interactions between co-infecting strains of a pathogen can have significant influences on disease epidemiology and evolution; therefore the dynamics of multi-strain infections is an important area of research. We stained 'Bd' cells with 2 fluorescent BODIPY® fatty acid probes to determine whether these can potentially be used to distinguish and track 'Bd' cell lines in multi-strain experiments. 'Bd' cells in broth culture were stained with 5 concentrations of green-fluorescent BODIPY FL and red-fluorescent BODIPY 558/568 and visualised under an epifluorescent microscope for up to 16 d post-dye. Dyed strains were also assessed for growth inhibition. The most effective concentration for both dyes was 10 µM. This concentration of dye produced strong fluorescence for 12 to 16 d in 'Bd' cultures held at 23°C (3 to 4 generations), and did not inhibit 'Bd' growth. Cells dyed with BODIPY FL and BODIPY 558/568 can be distinguished from each other on the basis of their fluorescence characteristics. Therefore, it is likely that this technique will be useful for research into multi-strain dynamics of 'Bd' infections.
