Figure 7. — Viral genomes from contact-exposed mallards can have more nucleotide changes compared to mallards directly-inoculated with virus, but no differences in measurements of diversity were observed. Samples included in these analyses are grouped according to mode of exposure and includes swabs from the medium and high dose groups. (A) Number of nucleotide changes observed in viral genomes from mallards that were directly inoculated with virus or contact-exposed. (B) Nucleotide changes classified according to which gene segment they were found. Statistical comparisons were made with the same gene between the two groups. (C) Mean frequency of all SNVs per sample. (D) Total number of SNV sites per sample. (E) Shannon entropy scores per sample. *p<0.05 using Mann-Whitney test.
