  1. group A: rabbits underwent both catheterization and inoculation; group A1: the catheter was removed immediately after catheterization; group A2: the catheter was removed 24 h after catheterization; group A3: the catheter was kept in the right heart until rabbit death; group B: rabbits only inoculated; group C: rabbits only underwent catheterization; MBC: mean bacterial count; NBTV: nonebacterial thrombotic vegetation; NA: not applicable.
