Multidrug-Resistant Serratia fonticola Causing Diabetic Foot Infection: A Rare Case Highlighting Emerging Antimicrobial Resistance

Year: 2026

Type: article

Abstract: Diabetic foot infections are commonly caused by Gram-positive cocci and Enterobacteriaceae. Isolation of Serratia fonticola is very rare. Here, we report a case of multidrug-resistant Serratia fonticola isolated from a chronic diabetic foot ulcer in a patient with poorly controlled diabetes. The case highlights the importance of microbiological evaluation in non-healing wounds and raises awareness of unusual resistant pathogens in routine clinical practice. A 56-year-old female patient with poorly controlled diabetes developed a non-healing foot ulcer following minor trauma. Culture revealed multidrug-resistant Serratia fonticola. The patient improved with glycemic control, debridement, and culture-directed antibiotics.
