Objectives: To describe the bacterial etiologies of sepsis at Thai Nguyen A Hospital, in 2025.
Subjects and methods: A cross-sectional descriptive study was conducted on positive blood culture samples from hospitalized patients at Thai Nguyen A Hospital, from January to September 2025. Blood culture samples were isolated and bacterial species were identified according to standard procedures at the Department of Biochemistry - Microbiology. Data were collected and analyzed using WHONET software and Microsoft Excel.
Results: Among 463 blood culture samples, 61 were positive (13.2%). Sepsis was most common in patients aged ≥ 60 years (60.7%), and males accounted for 59% of cases. Gram-negative bacteria predominated (70.5%), with E.coli being the most frequently isolated pathogen (46.5%), followed by K.pneumoniae (25.6%) and A.hydrophila (11.6%). Gram-positive bacteria accounted for 29.5% of isolates, mainly S.aureus (88.9%). No cases of fungal bloodstream infection were identified.
Conclusions: Gram-negative bacteria were the predominant etiological agents of sepsis at Thai Nguyen A Hospital, with E.coli and K.pneumoniae accounting for the highest proportions.
