Diversity of Opa proteins in isolates from asymptomatic carriagea
| Locus | No. of alleles | No. of SV variants | SV family | No. of HV1 variants | No. of HV1 families | No. of HV2 variants | No. of HV2 families | No. of HVRCs |
|---|---|---|---|---|---|---|---|---|
| opaA | 93 (12.4) | 8 (28.1) | 4 | 47 (48.3) | 13 | 61 (34.7) | 21 | 38 |
| opaB | 88 (12.0) | 11 (26.9) | 4 | 58 (42.4) | 18 | 58 (35.6) | 21 | 43 |
| opaD | 75 (15.0) | 15 (25.7) | 4 | 44 (42.8) | 14 | 51 (43.6) | 19 | 32 |
| opaJ | 61 (15.0) | 15 (30.4) | 5 | 36 (46.7) | 16 | 36 (41.5) | 18 | 30 |
a
Opa diversity is determined by alleles, variable-region sequences (the numbers of SV, HV1, and HV2 sequence variants observed are given), sequence families, and HV1-HV2 sequence family combinations (HVRCs). Percent distances are given in parentheses for nucleotide alleles and amino acid sequence data.
