The survey of antibiotic resistance of the bacteria that cause infections isolated at Can Tho University Medicine and Pharmacy Hospital in 2021

Abstract

Background: The rate of antibiotic resistant bacteria increases dramatically, therefore choosing antibiotics for treatment of bacterial infections is more and more difficult. Objectives: 1).

To identify the bacterial agents which caused infectious diseases isolated from patient samples and some related factors; 2). To describe the antibiotic resistance of isolated bacteria. Materials and methods: 627 bacterial strains were isolated and identified. Antimicrobial susceptibility testing were done by MicroScan. Results: The predominance of isolated bacteria is S. aureus (22.8%).

Other isolated bacteria are Staphylococcus spp. (17.4%), S. pneumoniae (16.2%), Klebsiella spp. (11.9%) and E. coli (9.7%). The resistance of S. aureus are high level with erythromycin (71.6%), clindamycin (78.7%), gentamycin (50.3%); S. aureus resistant to vancomycin are (10.4%). The resistance of Staphylococcus sp are low level with erythromycin (67.0%), clindamycin (57.5%), levofloxacin (50.5%). High level resistance of S. pneumonia is erythromycin (84.2%). High level resistance of E. coli are aztreonam (81.7%), piperacillin and levofloxacin (78.7%). High level resistance of Klebsiella spp. is piperacillin (83.8%). High level resistance of Pseudomonas spp. are ciprofloxacin (38.1%), piperacillin (38.6%) và levofloxacin (40.0%). Conclusions: S. aureus accounted for the highest percentage with 22.8%, bacterial strains with multi-antibiotic resistance accounted for a high rate.
