hayi, but are only considered to be topotypes
(thus no formal type status) since Jordan's (1885a) description of the species was based on ten specimens that had been removed from the original series and sent to Jordan for study (Gilbert 1998).

strains of bluetongue virus serotype 16 (BTV-16) from India," Advances in Animal and Veterinary Sciences, vol.
We think that the species deserves to be reinstated by finding topotype
The Ugandan SAT 3 viruses should be classified within a single topotype
(V), but this requires modification of the topotype
definition used previously (5).
The specimens from samples K25 to K28 of the Boghu section are almost identical in morphological characters to the topotypes
and considered here as conspecific.
Furthermore, FMDV O/SEA topotype
(Mya98) was also detected in China in 2003 and in Mongolia in 2004.
Phylogenetic comparisons of Seg-3 sequences have been used to identify different BTV topotypes
and distinguish different Orbivirus species (4).
Another specimen, the ventral valve PSU 161/7, is a topotype
(illustrated by Gravitis 1981, p.
All but 3 of the 55 FMDV serotype O Ethiopia isolates examined in our study fell into a single topotype
, East Africa (EA)-3 (Figure 1).
Some FMDV O topotypes
had a more limited spread than the ME-SA topotype
Strain 97-103 was compared antigenically in detail with the Egyptian Eg-101 topotype
strain of WNV (16), a representative of WNV lineage 1 (clade 1a).
