Antimicrobial resistance at Hai Phong International Hospital in 2021

Abstract

Retrospective study describing the current situation of antibiotic resistance at Hai Phong International Hospital in 2021 from 2429 positive bacterial specimens. The results showed that the most common infectious agent was E. coli (24.9%), followed by Strep. agalactiae (24.7%) and S. aureus (12.2%). Bacteria are mainly isolated from urine, genital fluid and puss specimens. E. coli was resistant to trimethoprim/ sulfamethoxazol (67.3%), cefuroxime (55.1%), cefotaxime (51.1%), ciprofloxacin (45.2%) and
levofloxacin (43.6%). The ESBL production rate of E. coli strain was up to 62.5%. Gram - negative bacteria causing respiratory infection diseases such as M. catarrhalis and Haemophilus spp. had a markable rate of resistance to oral antibiotics widely used in the
community such as amoxicillin/clavulanate (47.0 - 100%), macrolide group (79.6%). S. aureus is 77.3% resistant to methicillin and the rate of clindamycin resistance of S. aureus is notable of 81.8%. The rate of Strep. pneumoniae resistant to oral antibiotics is very high including levofloxacin (100%), erythromycin (98.2%) and cefuroxime (81.8%).
