Evaluation of Antimicrobial Resistance Patterns of Strains Isolated among COVID-19 Patients in Brazil Typed by Fourier-Transform Infrared Spectroscopy.

This study aimed to characterize strains isolated from hospitalized patients during the COVID-19 pandemic. This was achieved using phenotypic and molecular techniques, including their antimicrobial resistance profile and biofilm formation. Eighteen strains were isolated from a hospital in Rio de Janeiro, Brazil, and identified by VITEK2, MALDI-TOF/MS (VITEK MS and MALDI Biotyper), and 16S rRNA sequencing.

Assessment of the microbiological quality of natural mineral waters according to the manufacturing time of 20 L returnable packs in Brazil.

This study aimed to assess the microbiological quality of natural mineral waters commercialized in 20 L returnable packs in Brazil by investigating the presence of bacteria and viruses in packs with different manufacturing times (Tm). With this purpose, 99 water samples from 33 lots (n = 3/batch) of 15 brands, obtained from packs with three intervals of Tm, were analyzed. Total coliforms (16.
