化脓性脑膜炎 Here is another example of an acute meningitis from bacterial infection. The cerebrospinal fluid(csfiin such cases typically has a low glucose, high protein, and many PMNs. A gram stain should be done to identify organisms

Here is another example of an acute meningitis from bacterial infection. The cerebrospinal fluid (CSF) in such cases typically has a low glucose, high protein, and many PMN's. A gram stain should be done to identify organisms

a0命 3 a gram stain reveals gram negative diplococci within a neutrophil, typical for Neisseria meningitidis Gram stain and culture can be performed on cerebrospinal fluid obtained via lumbar puncture. A variety of bacteria can cause meningitis, but several are more common, and have an incidence more frequent at certain ages:
