On 2013-09-25, the Rospotrebnadzor of Moscow, Russia released a set of human pH1N1 sequences without age or gender at GISAID, including 6 Fatal cases. The Neuraminidase segments were not released.
One HA segment sampled in late January 2013 from Astrakhan [map], near the Caspian Sea, [EPI471830] strongly suggests Emergent H7N9 involvement. This Astrakhan H7N9-related viral Hemagglutinin displays a standard Emergent H7N9 amino at 179V on a pH1N1 Clade2:188T background. The HA 179V is Novel to pH1N1 after more than 4 years of pH1N1 circulation in humans. HA 89G, found in the H7N9 reservoir, is co-located on this same pH1N1 sequence. Polymorphisms at two antigenic amino positions practically adjacent, HA 129Q and HA 131L, provide grist for the Host-Transition mill.
Contemporary sequences from Spain carry homology as well as an unusual change adjacent to these odd aa129 and aa131 positions from the Russian Federation:
- HA 477M SpainCatalonia5925S_29F_2013_02_05
- HA 132S SpainMurcia164_80F_2013_01_30_s
HA 219T, also seen in the H7N9 reservoir, is demonstrated in Kazan [map], [EPI471827].
