International interlaboratory trials on rabies diagnosis: An overview of results and variation in reference diagnosis techniques (fluorescent antibody test, rabies tissue culture infection test, mouse inoculation test) and molecular biology techniques

► Improvement of rabies diagnosis in bat strains is needed. ► RT-PCR shows the lowest rate of false negative results among techniques. ► RTCIT and MIT present the lowest proportion of false positive results among techniques. ► Many variations occur between laboratory procedures. ► Standardisation of laboratory procedures at international level have to be carry on.
