“…ITV causes a neuroparalytic disease with symptoms similar to those induced by BAGV, despite the fact that in adult turkeys, ITV may lead to high morbidity and mortality. This virus was previously reported to be synonymous of BAGV; however, until now, they have not been officially classified as members of the same species [ 2 , 3 ]. In addition to the lack of segregation into different monophyletic clusters in phylogenetic trees, and low inter-BAGV/ITV genetic distances, in agreement with previously published results [ 3 ] both PCOORD and network reconstruction were again not able to separate BAGV and ITV, strengthening the idea that ITV and BAGV are different strains of the same viral species.…”

“…Within the Flavivirus genus, Bagaza virus (BAGV) is a member of the Ntaya group, along with five other species, namely Ntaya virus (NTAV), Ilheus virus (ILHV), Tembusu virus (TMUV), Rocio virus (ROCV), and Israel turkey meningoencephalomyelitis virus (ITV). BAGV shares high sequence similarity with ITV, which was isolated for the first time in 1958 from domesticated turkeys in Israel and later, in 1978, from South African turkeys [ 2 , 3 ]. Due to their high nucleotide sequence identity, both viruses have been suggested to belong to the same species [ 3 ].…”

In September 2021, Bagaza virus (BAGV), a member of the Ntaya group from the Flavivirus genus, was detected for the first time in Portugal, in the heart and the brain of a red-legged partridge found dead in a hunting ground in Serpa (Alentejo region; southern Portugal). Here we report the genomic characterization of the full-length sequence of the BAGV detected (BAGV/PT/2021), including phylogenetic reconstructions and spaciotemporal analyses. Phylogenies inferred from nucleotide sequence alignments, complemented with the analysis of amino acid alignments, indicated that the BAGV strain from Portugal is closely related to BAGV strains previously detected in Spain, suggesting a common ancestor that seems to have arrived in the Iberia Peninsula in the late 1990s to early 2000s. In addition, our findings support previous observations that BAGV and Israel turkey meningoencephalitis virus (ITV) belong to the same viral species.
