摘要

Bdellovibrio bacteriovorus is an agent that stands out with its predatory properties and has recently been used against pathogens that are frequently resistant to antibiotics. The study was conducted experimentally to determine the effect of dressing application containing Bdellovibrio bacteriovorus on superficial incisional surgical site infection caused by Staphylococcus aureus in mice. In the study, mice were divided into 6 different groups, BB: B. bacteriovorus; NC: Negative Control; PC: Positive Control Methicillin Resistant S. aureus; MRSA + BB: Methicillin Resistant S. aureus + B. bacteriovorus dressing; MRSA + V: Methicillin Resistant S. aureus + Vancomycin; MRSA + BB + V: Methicillin Resistant S. aureus + B. bacteriovorus dressing + Vancomycin group. The treatment procedures were applied over a period of 3 days. Infection symptoms were monitored and recorded at the 24th, 48th, and 72nd hours. In the Staphylococcus aureus + Vancomycin group, all mice developed edema, redness, and fever at 24 h. At 48 h, all mice exhibited edema and redness, with 50% showing fever. At 72 h, 70% of the mice showed edema and redness, and 10% showed fever. In the Staphylococcus aureus + Bdellovibrio bacteriovorus + Vancomycin combined treatment group, all mice exhibited edema, redness, and fever at 24 h. At 48 h, only 20% of the mice showed redness. At 72 h, no edema, redness, fever, purulent discharge, or suture dehiscence was observed. Sepsis developed in 2 of 10 mice in the Staphylococcus aureus + Bdellovibrio bacteriovorus + Vancomycin group. The most effective treatment was in the Staphylococcus aureus + Bdellovibrio bacteriovorus + Vancomycin group. It was determined that sepsis findings were the least in the Staphylococcus aureus + Bdellovibrio bacteriovorus + Vancomycin group. B. bacteriovorus holds the potential to be an effective control agent in preventing or slowing resistance development.
