PATHOGENS ASSOCIATED WITH BACTERIAL BLOODSTREAM INFECTIONS AT THE FACILITY 2 OF NATIONAL HOSPITAL FOR TROPICAL DISEASES IN DONG ANH DISTRICT (2018 - 2020)

Abstract

Objectives: 1. Identifying the pathogens associated with bacterial BSIs at the ability 2 of NHTD in Dong Anh district from 2018 to 2020. 2. Identifying antimicrobial susceptibility of bacteria isolated from blood samples.Subjects and methods: A descriptive study was conducted at the National Hospital for Tropical Diseases between January 2018 and December 2020. Cases of BSI were determined from records in the microbiology department with positive two blood cultures in the first episode.Results: A total of 330 patients with BSI were included for microbiological analysis. The predominant pathogens were: K. pneumoniae (15.1%), E. coli (14.2%), S. aureus (14.2%),Acinetobacter baumannii (6.8%) and Stenotrophomonas maltophilia (5.3%). There were two species with a high proportion of extended - spectrum beta - lactamase (ESBL) production among Enterobacteriaceae were E. coli (68.8%) and K. pneumonia (15.7%). All of S. aureus isolated strainswere susceptible to vancomycin and linezolid.Conclusions: Enterobacteriaceae (predominantly K. pneumoniae and E. coli) is the most common cause of bloodstream infections in a tertiary referral clinic in NHTD (a branch at Dong Anh district) in 2018 - 2020.
