Report of a Fatal Purulent Pericarditis Case Caused by ST11-K64 Carbapenem-Resistant Hypervirulent .

The report describes a 44-year-old female patient who died of the rare acute purulent pericarditis caused by (KP). The genomic analysis revealed an extensively drug-resistant ST11-K64 KP strain from five isolates (blood cultures, urine, ascites, pericardial effusion, and sputum). Several high virulence (hv) and carbapenem-resistant (CR) genes were identified in the pericardial effuse isolate. The isolates showed low resistance to healthy human serum. This study highlights the potential lethality of CR-hvKP infections in patients suffering from underlying comorbidities such as diabetes mellitus and chronic ailments.
