The bacteria that cause respiratory tract infections in Viet Tiep Hospital, 2018 - 2020

Abstract

Respiratory tract infections are the most common of all bacterial infections, especially lower respiratory tract infections. Bacterial pathogens and antibiotic resistance tend to increase. In this research, we carried out culturing, isolating, identifying and making antibiotic resistance for 13.771 respiratory tract samples obtained in 3 years 2018 - 2020
from patients at Viet Tiep Friendship Hospital, Hai Phong. Objective: 1) Determine the rate of common pathogens causing respiratory tract infections. 2) Determine the rate of antibiotic resistance of isolated bacteria. Results: Positive culture rate was 38.5%, the sex ratio was 71.66% male and 28.34% female. The mean age of patients was 66.71±16.56 years. Gram-negative bacteria accounted for 90.17% of which P.aeruginosa 25.54%, Acinetobacter spp 25.31%. Other bacteria were K.pneumoniae, S.aureus and E.coli are 18.77%, 5.30% and 4.22%, respectively. P.aeruginosa and Acinetobacter spp were resistant to most of the tested antibiotics. The rate of ESBL - producing K.pneumoniae was 28%, carbapenem resistance was 28.5% with MEM and 26.4% with IPM. S.aureus is resistant to most β-lactam antibiotics, almost absolutely resistant to PEN (97.1%). Conclusion: The causes of respiratory infections are diverse and the patterns of antibiotic resistance are very different, which presents a real challenge in the diagnosis and treatment of respiratory infections.
