V. Investigation of the genomic context of the T6SS gene cluster.
1. BLASTp searches of the proteins encoded by T6SS gene cluster and its flanking regions against the mobile genetic elements database, ACLAME.

2. BLASTp searches of the proteins encoded by T6SS gene cluster and its flanking regions against the virulence factor database, VFDB.

3. BLASTp searches of the proteins encoded by T6SS gene cluster and its flanking regions against against the antibiotic resistance database, ARDB.
