Abstract
Bdellovibrio bacteriovorus is a bacterial agent that stands out for its ability to act as a predator against gram-negative bacteria and has found application against antibiotic-resistant pathogens. The aim of this study is to determine the efficacy of Bdellovibrio bacteriovorus against antibiotic-resistant pathogens, particularly those causing infections in surgical incision sites. A total of 6 experimental groups were created in mice, and surgical area infections were initiated with Klebsiella pneumoniae in incision sites. The effects of antibiotics and Bdellovibrio bacteriovorus alone or in combination were compared to the control group. In the Bdellovibrio bacteriovorus treatment group, edema and redness were observed in all mice at 24th hours, in 20% of mice at 48th hours, and in none at the 72 nd h. A significant difference was observed in the Bdellovibrio bacteriovorus treatment groups in reducing Klebsiella pneumoniae burden in the incision area compared to antibiotics alone or Bdellovibrio bacteriovorus + antibiotics, (p < 0.001). Likewise, cytokine level determinations indicated that B. bacteriovorus applications generated a therapeutic response without inducing an inflammatory response.
