On 2011-10-31, the Institut Pasteur Hellenique deposited one human pH1N1 HA fragment sequence at GISAID of 216 amino acids (aa35 to aa220), documenting roughly 38% of a full pH1N1 Hemagglutinin segment. GreeceAthens7033_75M_2011_02_22_s was sampled from a 75 year old male, hospital inpatient. This hypermorphic fragment patterns onto Clade5: 208K_219V, a highly zoonotic, recently emergent series with a sequence count that has quickly accumulated to triple digits.
Two dispersed polymorphisms, each novel to pH1N1.Clade5, appear on this Greek sequence. HA 77R, a novel Clade5 revision, is rare to the human pandemic and is emergent on Clade2 (3 instances). Those 3 Clade2, HA 77R-bearing HA segment sequences are hypermorphic (accounting for 48 total HA changes); however, no HA cross-over onto this Greek sequence occurs from the full superset of polymorphisms with HA 77R. HA 169T, also novel to Clade5, is rare to the human pandemic and is found once on Clade2, the numerically dominant series for human pH1N1.
Avian H13 serotypes share significant homology with pH1N1.Clade5 and this Greek sequence. Given the serology background of the more recently discovered Hemagglutinin forms above H12 (~30 years for H13 to ~6 years for H16), question arise concerning cross-serotype compatibility. Returning to the archives after these recent discoveries, investigators repeatedly found that H16 samples from the past had been mis-typed on first inspection to various Hemagglutinin forms (H1, H7, H13) due to cross-reactive serology on various inhibition panels. Serotypes known to infect humans, including H1 and H7, featured in those earlier mistaken categorisations.
Precise discernment of the exact relationship between the current human pandemic H1N1 and the more recently discovered Hemagglutinin forms (H13 to H16) merits evaluation due to the significant H13 homology with the heavily zoonotic and rapidly emergent pH1N1.Clade5 and the High CFR pH1N1.Clade1.Upsilon.

On 2011-10-27, the Instituto Nacional de Enfermedades Respiratorias from the Centro de Investigacion en Enfermedades Infecciosas of Mexico deposited a group of human pH1N1 sequences at GenBank and GISAID. The deposit is composed of HA segments, 14 sequence fragments of 232 amino acids (aa38 to aa269), each documenting roughly 41% of a full pH1N1 Hemagglutinin segment. Various homology to Clade1.Upsilon exists on 5 of the sequences.
This Mexican genetic data supports an investigation entitled, H1N1pdm HA D222 variants associated with severity and mortality in patients during a second wave in Mexico and their pathogenicity in mouse model. Mexico City, Mexico is the geography indicated on the sequence names. Each sequence is annotated with gender and isolation source (nasopharyngeal swab), while 12 of the 14 also indicate the subject age. Subject ages range from 23 to 54 years old, all outside the general severity range for seasonal influenza (under 2 years old or over 60 years old). The sample dates span 2009-10-01 to 2010-04-05 with no case-level specification of treatment protocol, clinical progression or clinical outcome.
The severity and fatality correlation in cases with polymorphisms at amino acid position 222 (aa225 in H3 numbering) was established very early in the pandemic. The issue of sample location has been repeatedly posed, with ongoing discussion that samples taken from the lower respiratory tract are more probable to produce valid evidence of aa225 revisions. This INER deposit, relying entirely on upper respiratory swabs, documents cases where aa225 revisions are found in the upper airway. The individual details of clinical progression and outcome (severe v. fatal) will establish measurable correlation to the upper respiratory sample location.
Four of the samples show multi-nucleotide ambiguity at amino acid position 225 (contiguous mixed traces, residues 715 and 716) producing a codon of rrT. That sequencing outcome of rrT demonstrates the presence of wild type D225 with both 225G and 225N, hypermorphism at a single amino acid position. Overall, ten of the fourteen sequences demonstrate a mixed peak (ambiguity) at one or more nucleotides that build aa225. MexicoCityINER3_NP_47M_2009_10_15 [EPI341034] illustrates the highly variant nature of the pH1N1 reservoir Receptor Binding Site aa225 with two rare values, 225A and 225V, in a mixture without wild type (D225) and with no additional polymorphisms.

On 2011-10-27, the Instituto Nacional de Enfermedades Respiratorias from the Centro de Investigacion en Enfermedades Infecciosas of Mexico deposited a group of human pH1N1 sequences at GenBank and GISAID. The deposit is composed of HA segments, 14 sequence fragments of 232 amino acids (aa38 to aa269), each documenting roughly 41% of a full pH1N1 Hemagglutinin segment. Various homology to Clade1.Upsilon exists on 5 of the sequences.
This Mexican genetic data supports an investigation entitled, H1N1pdm HA D222 variants associated with severity and mortality in patients during a second wave in Mexico and their pathogenicity in mouse model. Mexico City, Mexico is the geography indicated on the sequence names. Each sequence is annotated with gender and isolation source (nasopharyngeal swab), while 12 of the 14 also indicate the subject age. Subject ages range from 23 to 54 years old, all outside the general severity range for seasonal influenza (under 2 years old or over 60 years old). The sample dates span 2009-10-01 to 2010-04-05 with no case-level specification of treatment protocol, clinical progression or clinical outcome.
The severity and fatality correlation in cases with polymorphisms at amino acid position 222 (aa225 in H3 numbering) was established very early in the pandemic. The issue of sample location has been repeatedly posed, with ongoing discussion that samples taken from the lower respiratory tract are more probable to produce valid evidence of aa225 revisions. This INER deposit, relying entirely on upper respiratory swabs, documents cases where aa225 revisions are found in the upper airway. The individual details of clinical progression and outcome (severe v. fatal) will establish measurable correlation to the upper respiratory sample location.
Four of the samples show multi-nucleotide ambiguity at amino acid position 225 (contiguous mixed traces, residues 715 and 716) producing a codon of rrT. That sequencing outcome of rrT demonstrates the presence of wild type D225 with both 225G and 225N, hypermorphism at a single amino acid position. Overall, ten of the fourteen sequences demonstrate a mixed peak (ambiguity) at one or more nucleotides that build aa225. MexicoCityINER3_NP_47M_2009_10_15 [EPI341034] illustrates the highly variant nature of the pH1N1 reservoir Receptor Binding Site aa225 with two rare values, 225A and 225V, in a mixture without wild type (D225) and with no additional polymorphisms.
