| 21. | These two viruses were first differentiated by host range.
|
| 22. | The natural reservoir, host range, and mode of transmission of the organism are still unknown.
|
| 23. | Changes in host range have occurred frequently and independently among strains within this species complex.
|
| 24. | These hosts range is sorghum, maize, and Johnson grass.
|
| 25. | The host range for this virus includes species of " Atriplex ", " fodder beet.
|
| 26. | Host range among the mammalian orders is non uniform.
|
| 27. | However, research suggests that this species may comprise several unrecognized taxa with narrower host ranges.
|
| 28. | This specificity determines the host range of a virus.
|
| 29. | With time, using serological, host range studies and eventually sequence data, this proved to be true.
|
| 30. | These orders span viruses with varying host ranges.
