Analysis of Coinfections with A/H1N1 Strain Variants among Pigs in Poland by Multitemperature Single-Strand Conformational Polymorphism

Figure 2

Distinct genetic variants (A–F) of the influenza A/H1N1 virus revealed by MSSCP of the collected isolates after clonal selection. DNA fragments corresponding to unique band patterns that occurred repeatedly during analyses of clones from five swine isolates were denatured and were separated on 10% polyacrylamide gel using MSSCP method under optimal electrophoretic conditions. DNA was visualized by silver staining.
