Diagnostics, epidemiological observations and genomic subtyping in an outbreak of pullorum disease in non-commercial chickens

The PFGE, MLVA and high-throughput sequencing results suggested at least two different sources of infection or a common genetically mixed source in 2012. High-throughput sequencing is useful both for subtyping of S. Pullorum and may also be used for differentiating between the two biovars Pullorum and Gallinarum.
