However, Seg-7 from the Chinese strain of BTV-12 groups within western group 1, suggesting some movement of strains between geographic regions.
The data presented here suggest that the Schu S4 laboratory strain is the most likely source of the reported European isolates of F. tularensis subspecies tularensis and indicate that anthropogenic activities, such as movement of strains or animal vectors, account for the presence of these isolates in Europe.

Further, in plants, movement of strains or prediction of which endemic strains will reach outbreak levels can be improved by genetic tracing, now that sequencing is becoming much less expensive.
Genetic flow or migration rate, Nm, refers to the movement of strains between populations and sub-populations and sets a limit as to how much genetic divergence can occur.
The ctrA mutation blocks the production of the flagellum [21], and so the movement of this strain is due to a flagellum-independent mechanism [22].
Air travel and migration have increased the movement of virus strains around the world.
Use of A. tigrinum as fishing bait has resulted in the movement of ATV strains over large distances, as well as the potential introduction of more virulent strains from bait farms or bait shops into wild populations (Jancovich et al. 2005; Storfer et al. 2007).
The movement of different strains of IAPV between honey bees and bumble bees was successfully tracked.
From a public health perspective, confirming CCHF in Sudan and determining which virus lineages may be present in this region will provide a more detailed understanding of the movement of virus strains and identification of areas at risk for CCHFV.
