Bacterial pathogens may breach the blood-brain barrier (BBB) and invade the central nervous system through paracellular and/or transcellular mechanisms. Transcellular penetration, e.g., transcytosis across the BBB has been demonstrated for Escherichia coli K1, group B streptococcus, Listeria monocytogenes, Citrobacter freundii and Streptococcus pneumonia strains. Genes contributing to invasion of brain microvascular endothelial cells include E. coli K1 genes ompA, ibeA, ibeB, and yijP. Understanding the mechanisms of bacterial penetration across the BBB may help develop novel approaches to preventing bacterial meningitis.
