Inclusion Body disease
Inclusion Body Disease (IBD) often affects boas and pythons and currently has no cure. This disease has been known to wipe out entire colonies of snakes in someone's possession and while it cannot be eradicated steps can be taken to try to prevent the spread from infected to healthy animals. Following proper quarantine procedures, including keeping new snakes away from current animals for at least six months, can provide the proper time period for the snake to show symptoms if they are inflicted. It is also important to wash and sanitize between handling different snakes whether cleaning enclosures, feeding, or filling water bowls.
