I have Serratia Marcescens infection after tummy tuck. Is it dangerous, and how did I get it? (Photo)

if your surgeon is a board certified plastic surgeon.  he is very well trained in wound care. it looks like he did everything perfectly apprpriately  there is a difference between colonized and infected.  there are always bacteria in open wounds. they are never sterile.. the bacteria was not the issue in your wound healing.  it was blood supply.  it looks like your wound is now healing nicely. you may have  a slightly wider scar that could be revised at any time.  those t junctions can often be problematic

It is common to have wound healing problems in this area in Tummy Tucks. There is decreased vascular supply in this area leading to necrosis or death of the skin and fat underneath. Your PS did appropriately debride the area and started you on local wound care it appears as the wound has some pink tissue along with some necrotic tissue. With normal wound care it will close on its own as your plastic surgeon said. All open wounds are infected and will usually culture some bacteria. Your PC sent you to a wound clinic that have protocols such as culture every wound. Nothing really wrong with that. Take the antibiotics and do local wound care and the closure will occur most likely like your PS said. Keep your PS informed what you are doing differently. This is a very small wound and should do well.

All open wounds are infected.  The infection and organism is not important unless it becomes invasive causing cellulitis and abscesses.  The serratia may have colonized the wound but is not likely the entire cause of the wound not healing.  In this area blood supply is a real challenge.  Conservative wound care will likely heal the area.  It just takes time.  Only treat the infection if it becomes invasive and you experience fever, chills and redness of the surrounding normal skin.
