Abstract:
Objective To explore the impact of silver ions on the adhesion ability of Bacillus Calmette-Gueri vaccine on silicone tube surface. Methods Common and silver plated silicone tubes were cultured in BCG bacterial liquid for 30 days. A gas-bacilli was taken once every 3 days to measure OD value of microbial. The growth curve of BCG vaccine was made. The corresponding silicone tubes in divided different generations was removed and eluted based on the division cycle of BCG vaccine. The samples were inoculated on the solid medium for observing the colony growth amount, and adhesion curve was drawn. The silicone tube colony line was observed under the electron microscope at day 30. Results OD value and bacterial plaque number were less in silver silicone tube group than in common silicone tube group, with statistical significances (P < 0.05). Electron microscopy also showed that BCG adhesion on silver silicone tube group was relatively less than that on common silicone tube group. Conclusion Silver ions can reduce the adhesion of BCG vaccine on silicone tube surface and inhibit the growth of BCG vaccine.
