Identification of DENV and JEV in CSF samples from acute encephalitis syndrome cases in Myanmar by FRNT50, and virus isolation
| Sample ID | Age (year) | Gender | Day of collection | P/N ratio (Cut off = 2) | FRNT50 | Virus isolation | Diagnosis interpretation | ||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| JEV IgM | DENV IgM | Flavi IgG titer | JEV | DENV-1 | DENV-2 | DENV-3 | DENV-4 | ||||||
| CSF-35 | 3 | F | 4 | 3.7 | 1.2 | 8 | 40 | < 10 | < 10 | < 10 | < 10 | neg | JEV |
| CSF-37 | 9 | F | 6 | 7.8 | 3 | 13,604 | 20 | < 10 | < 10 | < 10 | < 10 | neg | JEV |
| CSF-42 | 0.6 | M | 7 | 10.4 | 1.8 | 9 | 80 | < 10 | < 10 | < 10 | < 10 | neg | JEV |
| CSF-61 | 10 | M | 7 | 19.2 | 11.4 | 42,470 | 140 | 20 | 40 | < 10 | 20 | neg | JEV |
| CSF-122 | 1.5 | M | 2 | 1.6 | 1.8 | 516 | ND | ND | ND | ND | ND | pos | DENV-1 |
CSF = cerebrospinal fluid; DENV-1 = dengue virus serotype-1; DENV-2 = dengue virus serotype-2; FRNT50 = 50% focus reduction neutralization test; JEV = Japanese encephalitis virus; pos = positive; neg = negative; ND = not done (shortage of CSF amount); F = female; M = male. Day of collection: the interval between disease onset and sample collection.
