Ticks infected in regions of the former territories of the USSR
| Tick species | Location | No. positive ticks/total examined | % infected ticks | Rickettsial species |
|---|---|---|---|---|
| Rhipicephalus pumilio | Astrakhan region | 2/65 | 3 | Astrakhan fever agent |
| Rh. pumilio | Astrakhan region | 1/65 | 1.5 | RpA4 genotype |
| Dermacentor nutallii | Siberia | 12/101 | 12 | Rickettsia sibirica |
| D. nutallii | Siberia | 4/101 | 4 | DnS14 and DnS28 genotypes |
| Rh. sanguineus | Crimea | 3/37 | 8 | R. conorii (Malish strain) |
1The received sequences of the new rickettsial agents have been deposited in GenBank. Sequences of ompA were deposited as two parts under accession numbers: DnS28, AF120018 and AF120019; DnS14, AF120021, and AF120020; RpA4, AF120022, and AF120023. The 16S rRNA gene and gltA sequences have been deposited in GenBank under accession numbers DnS28, gltA - AF120027, 16S rRNA gene AF120024; DnS14, gltA AF120028, 16S rRNA gene AF120025; RpA4, gltA - AF120029, 16S rRNA gene AF120026.
