QUESTION 1 With bacterial meningitis, we're going to see that the pathogens typically colonize part of the airway before ending up in the CSF via "hematogenous spread" Given that a root in the word hematogenous is "hema" how do these pathogens get from the airway to the CSF? O via the blood O they are carried there by macrophages O they burrow directly from the back of the throat to the arachnoid mater. QUESTION 2 We know that the LPS in the cell wall of Gram negative bacteria promotes inflammation. Inflammation is responsible for some of the signs and symptoms of meningitis. Given all this, can pathogens OTHER THAN Gram negative bacteria cause meningitis? O Yes; viruses and fungi are Gram positive pathogens that can cause meningitis. O No, LPS must be present for inflammation to occur. O Yes, for example the pneumococcus
