Abstract
The pandemic caused by SARS-CoV-2 brought damage to public health, especially in hospital settings, which became even more conducive to the colonization of opportunistic pathogens and, consequently, high bacterial resistance, thus limiting treatment options. This study analyzes reports of tracheal aspirate samples of patients hospitalized in the ICU COVID ward of a hospital in Brazil with the objective of: 1) investigating the bacterial profile of positive tracheal aspirate samples submitted to microbiological culture testing, and 2) analyzing the bacterial resistance profile of the most predominant bacteria. This is a quantitative descriptive study that collected data on the total number of tracheal cultures and their respective antibiograms of patients hospitalized in the ICU COVID ward, between the months of January and July 2021. The study showed a large increase in the number of respiratory tract infections in individuals affected by SARS-CoV-2, caused by opportunistic bacteria: 337 out of 489 samples were found to be positive. The most predominant bacterium, Klebsiella pneumoniae, was present in 143 samples and showed high levels of resistance to most of the antibiotics tested. The findings point to a worrying scenario when considering the length of the study and the number of reports that were analyzed.
