Abstract:
Objective To investigate the clinical characteristics,antimicrobial susceptibility of pathogens,and laboratory test results of patients with Vibrio vulnificus infection.Methods The clinical and etiological data,as well as laboratory tests were reviewed retrospectively for 14 patients with V.vulnificus infection,who were admitted to the 909th Hospital from May 2022 to November 2023.Results Overall,9 of the 14 patients(64.3%)had a history of exposure to seafood or seawater.Six patients(42.9%)had underlying diseases,such as hepatitis,coronary heart disease and diabetes mellitus.Eleven patients(78.6%)had a good outcome,while 3 patients(21.4%)had a poor outcome.A total of 18 strains of V.vulnificus were isolated,including 11(61.1%)strains from wound pus,and 7 strains(38.9%)from blood.V.vulnificus isolates were susceptible to ampicillin-sulbactam,piperacillin-tazobactam,imipenem,meropenem,tetracycline,ciprofloxacin,levofloxacin,trimethoprim-sulfamethoxazole,and chloramphenicol,but only 50.0%,55.6%,and 61.1%of the strains were susceptible to cefazolin,ampicillin,and amikacin,respectively.White blood cell count,neutrophil,C-reactive protein,prothrombin time,fibrinogen,activated partial thromboplastin time,D-Dimer,urea nitrogen,creatinine,uric acid,glutamic-pyruvic transaminase,glutamic oxaloacetic transaminase,lactate dehydrogenase,alkaline phosphatase,creatine kinase,creatine kinase isoenzyme MB,hypersensitive troponin I,myoglobin,procalcitonin,and N-terminal pro-brain natriuretic peptide were significantly increased in patients with V.vulnificus infection.Conclusions Wound pus and blood samples collected simultaneously for microbial culture can improve the detection of V.vulnificus.Early debridement and antibiotic combination therapy are vital for improving patient survival rate.
