Abstract

Objectives: To determine the prevalence of common UTI-causing bacteria and their antibiotic resistance
characteristics.
Subjects and methods: Patients with urinary tract infections diagnosis and requested for urine culture and
antibiogram with clear information and consistent with the diagnosis of UTI, were hospitalized at the Yen Bai
General provincial hospital from January 2022 to December 2022.
Results: 160 strains of microorganisms were isolated, including 158 strains of bacteria, 2 strains of fungi.
Gram-negative bacteria accounted for 97.5% of isolated bacterial pathogens, of which E. coli had the highest
rate with 48.1%, K. pneumoniae accounted for 20.3% and Acinetobacter baumannii 19%. The percentage of
E. coli strains producing ESBL was 52.6%. E. coli was resistant to all tested antibiotics at various degrees,
of which, resistance to cephalosporine, quinolone from 42.1 to 56.6% and resistance to carbapenem 5.3%.
K. pneumoniae was also resistant to all tested antibiotics at various degrees with the highest resistance to
cefotaxime, ceftriaxone (46.9%) and carbapenem resistance 9.4%. A. baumannii was resistant to all tested
antibiotics at various degrees with the highest resistance to cefotaxime (83.3%) and the lowest to amikacin,
imipenem (23.3%).
Conclusions: Common UTI associated bacteria isolated at Yen Bai General Hospital are E. coli, K. pneumoniae, A. baumannii. The isolates were resistant to all tested antibiotics at varius degrees with many strains resistant to carbapenem.
