For this purpose, the total GBP‐1 concentration was determined by GBP‐1‐ELISA in CSF samples of patients with bacterial meningitis (n = 20) and patients who were suffering from other non‐infectious diseases (n = 21) and was found to be increased in the meningitis patients compared to the controls (Fig. 5, diagram). The gene discussed is GBP1; the disease is meningitis.
