Gleichzeitig (!) 3 verschiedene H5N8 Virustypen in Japan! Aus Europa, aus Nordamerika, aus jap. Nutztierhaltungen.

We found that the H5 genes from our eight isolates belonged to clade 2.3.4.4 and were geneti
-
cally divided into three groups. The water isolate, A/
environment/Kagoshima/KU-ngr-H/2014(H5N, fell
into a phylogenetic cluster together with the European
isolates and was closely related to two wild duck
isolates in Japan (Group A, indicated in green in the
Figures). The first and second crane isolates, A/crane/
Kagoshima/KU1/2014(H5Nand A/crane/Kagoshima/
KU13/2014(H5N, were genetically similar to the North
American isolates (Group B, blue in the Figures). The
HA genes of the rest of our isolates (Group C, red in the
Figures), as well as a poultry isolate from Japan were
clearly distinct from those of the other recent H5N8
isolates. These findings suggest that three genetically
distinct groups of H5N8 HPAIVs were independently
circulating among the migratory birds at the Izumi
plain.
