Abstract

Backround: Infections due to Gram-negative bacteria are a serious problem in both hospitalized and community-dwelling patients. Objective: To determine the proportion of Gram-negative bacteria isolated from patients requiring Antibiograms at Can Tho General Hospital. Materials and method: Cross-sectional description of 1613 patients whose specimens were designated for antibiogram at Can Tho City General Hospital from June 2022 to June 2023. Results: There were a total of 29 Gram-negative strains isolated, accounting for 70.7%. The 3 strains of Gram-negative bacteria accounting for a high proportion are Escherichia coli (27.4%), Klebsiella pneumoniae (23.5%), and Acinetobacter baumannii (13.9%). Gram-negative bacterial strains isolated mainly in patients ≥60 years old. The ICU department has the highest number of specimens (84%). Sputum and urine are the two specimens containing the most Gram-negative bacteria (87.3%) and (89.3%), this difference is statistically significant (p<0.05). Conclusion: Among the total number of isolated samples, Gram-negative bacteria accounted for a higher proportion than Gram-positive and fungi. Thus, gram-negative bacteria are the main group of pathogens causing diseases in hospital departments, which is consistent with the general trend in medical facilities in Vietnam and around the world.
