Introduction Gum karaya (GK) is a natural polysaccharide with great potential in the treatment of chronic skin and soft tissue infections (SSTIs). The polysaccharide-based hydrogels keep a moist environment and stimulate faster moist wound healing. Supplementing this material with phage preparation can increase its antimicrobial effects. Methodology Four pigs (20 wounds, 5x5cm) were used in the experiment. The wounds were infected with Staphylococcus aureus (ST22). The first sampling verified a successful infection. The other 4 samplings monitored the treatment. A piece of tissue was taken as well as an impression of the wound surface. The tissue was processed and 10 µl of the suspension was added to the BA and MH with oxacillin. The impression was transferred from BA to MH. The plates were cultured at 37°C for 48 h. Then the colonies were counted, and numbers were converted to tissue weight (CFU/g). The impressions were scored quantitatively using a 1-4 scale. Results Testing showed a positive effect of the combination of GK with phage in both tissue and surface wounds. During the experiment, there was a gradual reduction of bacterial numbers in the tissues and in the surface impressions. The wound was gradually shrinking by the formation of healthy tissue. Conclusion GK-based hydrogels have been tested in vitro, where they showed an antimicrobial effect. These experiments in an animal model show that the effect is also demonstrated directly on the infected wound. This material could be a promising candidate for the treatment of chronic wounds.
