Three year old English Mastiff develops an infection in the tail. The analysis shows that it is caused by a multi-resistant Staphylococcus pseudintermedius – necrotizing fasciitis, also commonly called flesh-eating bacteria. Amputation is recommended, but the owner wants to try to save his dog's tail.
SertaSil is sent by courier to Texas, US and treatment started immediately. It consists of very thorough daily washing with tap-water followed by gently drying and the application of a fully covering layer of SertaSil. The wound is not covered by a dressing. SertaSil is used once daily for 4 days after which only tap-water and access of air is used, except for a single application Day 34.
No complications occurred during the treatment. The wound closed fully and has remained closed.

Amputation of tail recommended. Detected 5 days earlier in 3 year old Mastiff – otherwise healthy.
Day -9 to start of SertaSil.
Colleyville vet clinic, Texas US

Infection is rapidly spreading and the tissue is dying.

Dead tissue has mostly been removed, but the infection is continuing to spread.

The infection is rapidly spreading in the tissue and is causing tissue death. The redness is extending towards the rear part of the body, threatening to affect the torso itself.


Clear and rapid improvement.









Treatment after Day 4 still only consists of washing with tap-water and access to air.





Healthy scab correctly left in place. It will fall off by itself as the skin underneath matures.

Regeneration will continue over the coming months to years.
