H. pylori inhibits phagocytosis by JOSKM cells. JOSKM cells were infected with either H. pylori P12, PAI, or N. gonorrhoeae N303 alone or were infected with either H. pylori P12 or PAI for 2 h before the addition of N. gonorrhoeae N303. In these cases the uptake of N303 was assessed. The bacterial uptake was determined by using laser confocal microscopy. The percentage of infected cells containing at least one intracellular bacterium was determined. Results are the mean of at least three independent experiments.
