Comparison of CSF characteristics between human and rabbit during normal and TBM conditions.

Species	Normal	TBM
Human	Clear and colorless	Opalescent, turbid and slightly yellow in color
	No Coagulation	Coagulation
	Total cell count: Adult- 0–5 cells/mm3 Infants- 0–30 cells/mm3	Total cell count: 10–1000 cells/mm3 (Mainly monocytes, lymphocytes predominate and neutrophils present in the early stages)
	Glucose: 45–85 mg/dl	Glucose: <45 mg/dl
	Protein: 15–45 mg/dl	Protein: 100–500 mg/dl
	Specific gravity: 1.004–1.007
Rabbit	Clear and colorless	Turbid, cloudy and off-white in color
	No Coagulation	Coagulation
	Total cell count: 0–10 cells/mm3	Total cell count: 0–1500 cell/mm3 PMN: 80–400/mm3 Lymphocyte: 300–1200/mm3
	Protein- albumin: 0.015–0.019% Globulin: Absent	Protein: 0.03–0.8%
