Microbiological profile of multidrug resistant bacteria before and during COVID-19 in CHU Mohammed VI

Abstract

Background and Objectives: A new type of corona virus has caused Corona virus disease-19 and, subsequently, a global pandemic. All individuals are prone to the disease, so drastic measures were taken to prevent its spread. This study aimed to evaluate the impact of COVID-19 on the progression of the antimicrobial resistance rate by comparing two periods: before and during COVID-19. Materials and Methods: We used a cross-sectional design to investigate the Antimicrobial Resistance (AMR) rate before (03/2019 to 03/2020) and during COVID-19 (03/2020 to 03/2021) in a University Hospital in Marrakech. The data were analyzed using SPSS Version 25.0. Results: Among the 7106 specimens, there was a significant increase in the multidrug-resistant bacterial from 27.38% to 35.87% during COVID-19 (p<0.001), particularly in blood culture, cerebrospinal fluid, catheter, and pus. However, there was a non-significant change in puncture fluid, expectoration, protected distal sampling, joint fluid, stool culture, and genital sampling. A decrease in Multidrug-resistant bacteria (MDRB) was observed only in cytobacteriological urine tests (p<0.05). According to species, there was an increase in extended-spectrum beta-lactamase-producing Enterobacteriaceae, carbapenem-resistant Enterobacteriaceae, and methicillin-resistant Conclusion: In our study, it is particularly noticeable that the MDRB has increased. These results highlight the importance that the pandemic has not been able to slow the progression.
