Presence and absence of accessory virulence genes in V. cholerae O139 genome assemblies.
| Accessory virulence gene (N16961 locus ID or accession number) | Present in 48853_F01 | Present in 48853_G01 | Present in 48853_H01 | Present in 48853_A02 |
|---|---|---|---|---|
| ToxR (VC_0984) | Yes | Yes | Yes | Yes |
| Zona occludens toxin, Zot (VC_1458) | No | Yes | Yes | Yes |
| Accessory cholera enterotoxin, Ace (VC_1459) | No | Yes | Yes | Yes |
| Haemolysin, hlyA (VC_A0219) | Yes | Yes | Yes | Yes |
| Mannose-sensitive haemagglutinin, MSHA (VC_0398..VC_0414) | Yes | Yes | Yes | Yes |
| MARTX toxin, rtxA (VC_1451) | Yes | Yes | Yes | Yes |
| MARTX toxin accessory gene, rtxC (VC_1450) | Yes | Yes | Yes | Yes |
| HA/protease, hapA (VC_A0865) | Yes | Yes | Yes | Yes |
| Heat-stable enterotoxin NAG-ST (Accession # M85198.1) | No | No | No | No |
| Type III secretion system from V. cholerae AM_19226 (typically present in lieu of VPI-2; accession # AATY01000000) | No | No | No | No |
Gene presence and absence was determined using ACT67 to visualise BLASTn synteny plots, and using tBLASTx to scan assemblies using the NAG-ST nucleotide sequence as a query.
