Tickborne Encephalitis, Southwestern France
|Samples||Days after clinical onset||ELISA TBEV IgM (OD value)||ELISA TBEV IgG (OD value)||PRNT80 TBEV antibody titers||TBEV RT-PCR (10)||Virus culture|
*TBEV, tickborne encephalitis virus; IgM, immunoglobulin M; OD, optical density; PRNT80: plaque-reduction neutralization test (80%); RT-PCR, reverse transcription–PCR; CSF, cerebrospinal fluid; ND, not done. Boldface type indicates positive values.
†IgM capture and IgG indirect in-house assay were performed to detect IgM and IgG TBEV antibodies. The cut-offs were as follows: IgG cut-off 0.05; IgM cut-off 0.2. A PRNT was performed using the Hypr TBEV strain to determine the titer of TBEV-neutralizing antibodies.
