3.5 | Serotype SAT 2
Twelve serotype SAT 2 viruses within the SAT 2 topotype VII, distributed
between 2010-2017 were characterised (Figure 4). All of these Sudanese
sequences belonged to the Alx-12 lineage which also contains sequences
from FMD viruses collected from other countries including Egypt 2014 and
2017. Older Sudanese viruses (from 1977 and 2007-08) belonged to
topotype XIII and were related to viruses from Ethiopia.
