FIG. 1.

Comparative analysis of quantitative real-time RT-PCR results and results of RTCIT and DFA on a panel of patient specimens. Solid black bars indicate rabies viral RNA concentrations per mg in solid postmortem samples and per ml in fluid intravitam samples, respectively, as measured by real-time RT-PCR. Quantative real-time RT-PCR results have been transformed to log₁₀ RNA copies per mg and ml, respectively. Results of virus isolation by RTCIT for the respective postmortem and intravitam samples are indicated by + for a positive result and − for a negative result. Results of DFA are indicated by + for a positive result, − for a negative result, and nd for material not appropriate for DFA analysis.
