Bordetella-containing phagosomes in MH-S cells are acidic. The pH was determined with Oregon green-labeled bacteria in the acidic range and with fluorescein-labeled bacteria in the neutral range, as described in Materials and Methods. As an example, the kinetics of acidification of phagosomes containing B. pertussis strains are shown. Each experiment was performed three times, and the means of these data are presented with the vertical bars representing the standard deviation.
