Bacterial colonization of chronic leg ulcers: current results compared with data 5 years ago in a specialized dermatology department

Abstract

The results of our investigation demonstrate the current spectrum of the bacterial colonization in patients with chronic leg ulcers in a university dermatological wound centre in comparison to the last 5 years. In our institution we were able to demonstrate a shift of the detected bacterial species from gram-positive in direction to gram-negative germs. Beside the already known problems with MRSA, in future therapeutic strategies in patients with chronic leg ulcers the increasing amount of gram-negative bacteria and especially of P. aeruginosa should considered.
