In September 2010, an outbreak of disease in 2 wild bird species (red-legged partridge, Alectoris rufa; ring-necked pheasant, Phasianus colchicus) occurred in southern Spain. Bagaza virus (BAGV) was identified as the etiological agent of the outbreak. BAGV had only been reported before in Western Africa (Central African Republic, Senegal) and in India. The first occurrence of BAGV in Spain stimulated a demand for rapid, reliable, and efficacious diagnostic methods to facilitate the surveillance of this disease in the field. This report describes a real-time reverse transcription polymerase chain reaction (RT-PCR) method based on a commercial 5’-Taq nuclease-3’ minor groove binder DNA probe and primers targeting the Bagaza NS5 gene. The method allowed the detection of BAGV with a high sensitivity, whereas other closely related flaviviruses ( Usutu virus, West Nile virus, and Japanese encephalitis virus) were not detected. The assay was evaluated using field samples of red-legged partridges dead during the outbreak ( n = 11), as well as samples collected from partridges during surveillance programs ( n = 81). The results were compared to those obtained with a pan-flaviviral hemi-nested RT-PCR followed by nucleotide sequencing, which was employed originally to identify the virus involved in the outbreak. The results obtained with both techniques were 100% matching, indicating that the newly developed real-time RT-PCR is a valid technique for BAGV genome detection, useful in both diagnosis and surveillance studies.
