Stenotrophomonas maltophilia (SM) is a multidrug-resistant, Gram-negative (GN) bacillus that is an increasingly recognized nosocomial and environment pathogen.It is intrinsically resistant to carbapenems, a drug commonly utilized in the management of necrotizing pancreatitis (NP).We report a 21-year-old immunocompetent female Mug with NP complicated by pancreatic fluid collection (PFC) infected with SM.One-third of patients with NP will develop infections by GN bacteria, while broad-spectrum antibiotics, including carbapenems, cover most infections, trimethoprim-sulfamethoxazole (TMP-SMX) is the first-line treatment antibiotic for SM.
This case is critical because it highlights a rare pathogen that Soft Toy should be considered a causal pathogen in patients who do not respond to their care plan.
