*HBoV, human bocavirus; CSF, cerebrospinal fluid; Neg, negative; NA, not available; PMN, polymorphonuclear neutrophil: ND, not done; ESR, erythrocyte sedimentation rate; CRP, C-reactive protein.
†The following viruses were tested for herpes simplex virus (HSV) type 1, HSV-2, varicella-zoster virus (HSV-3), Epsetin-Barr virus (human herpesvirus [HHV] type 4), cytomegalovirus (HHV-5), (HHV-6), HHV-7, HHV-8, dengue virus, Japanese encephalitis virus, rubella virus, West Nile virus, yellow fever virus, tick-borne encephalitis virus, Nipah virus, measles virus, mumps virus, parainfluenza virus, respiratory syncytial virus, metapneumovirus, Chikungunya virus, Sindbis virus, Semliki Forest virus, eastern equine encephalitis virus, western equine encephalitis virus, poliovirus, Coxsackie virus, echovirus, enterovirus, lyssaviruses, and Chandipura virus. Bacteria were tested by PCR amplification of 16Sr RNA, followed by sequencing.
‡Reference values: leukocyte count <5 cells/mm3 and all lymphocytes; PMNs, none; protein, 20–45 mg/dL; glucose, 50–80 mg/dL or >50% of blood glucose level.
§Reference values: leukocyte count, 4,000–11,000 cells/mm3; PMNs, 40–60% of leukocyte count; lymphocytes, 20%–40% of leukocyte count; hemoglobin, men: 14–18 g/dL, women, (12–15 g/dL, children: 11–16 g/dL; ESR, <20 mm in1st hr., CRP, <12 mg/dL.
