RESUMEN
OBJECTIVE: Necrotising soft tissue infections (NSTIs) progress rapidly and mortality remains high, ranging from 10% to 30%, representing a significant challenge for health professionals. Early accurate diagnosis is crucial because timely and aggressive surgical intervention remains the number one indicator for a better clinical outcome. Understanding the microbial background of NSTIs would aid early diagnosis. PRESENTATION: We present a case of NSTI, in a seemingly healthy adult male, originating from a tooth abscess. The NSTI progressed rapidly, and eventually covered the patient's chest and abdominal skin and underlying soft tissue. RESULTS: Traditional blood and tissue culture only found Group C Streptococcus where 16S sequencing detected abundant Prevotella spp., a more likely causal organisms of the NSTI. The use of antibiotics with the approriate anaerobe coverage, in combination with timely surgical intervention, contributed to the ultimate successful clinical outcome. Complete wound healing and successful graft was achieved within one month of diagnosis of the microbes present. CONCLUSION: While surgical intervention remains the most important consideration in treatment of NSTI, correct identifcation of the microbial flora could also contribute to successful treatment.
