SURVEY OF ANTIBIOTIC RESISTANCE OF ISOLATED BACTERIAL STRAINS AT NINH THUAN PROVINCE GENERAL HOSPITAL IN 2023

Abstract

Objectives: Distribution of the proportion of bacterial isolates and their antibiotic resistance rate at Ninh Thuan Provincial General Hospital (NTPGH).
Subjects and methods: All bacterial isolates from various types of clinical specimens from a departments of NTPGH from October 1, 2022 to September 30, 2023.
Methods: Cross-sectional description.
Results and conclusions: Of the 993 samples designated for culture, 988 cultured samples contained pathogenic bacteria, accounting for 99.5%. Pus specimens account for the highest rate of 32.1%; Gramnegative bacteria account for 76% while Escherichia coli was found in 324 samples, accounting for 32.8%, the highest proportion. Escherichia coli resists ampicillin, bactrim, and tetracycline at 95.4%, 90.5%, and 75.8%, respectively. Staphylococcus aureus resists penicillin, azithromycin, erythromycin, clindamycin, oxacillin, and bactrim at 96.5%, 93.5%, 93.2%, 93.2%, 81.9%, and 75.0 %, correspondingly. Acinetobacter spp. resists cefotaxime at 100%, ceftriaxone (100%), bactrim (92.3%), ceftazidime (90.9%), cefepime (87.8%), tetracycline (84.7%), gentamycin (81 .4%), ciprofloxacin (80.0%), levofloxacin (78.9%), and piperacillin-tazobactam (76.9%). Klebsiella spp. resists ampicillin, and bactrim at 99.1%, and (86.7%),
respectively. Enterococcus spp. resists tetracycline at 85.7%. Proteus spp. resists tetracycline, bactrim, and ampicillin at 94.9%, (86.8%), and (78.3%), correspondingly. Pseudomonas aeruginosae resists ampicillinsulbactam, and ceftriaxone at 100%, and 75%, respectively.
