Microorganisms isolated from patients with COVID-19
Abstract
This study aims to identify microorganisms (bacteria and/ or yeasts) isolated from samples from patients held in the Intensive Care Unit of a Sentinel Hospital in the city of Maracaibo, with a confirmed diagnosis of COVID-19, during the period between January 1, 2020 and May 31, 2021. The antimicrobial susceptibility of the isolated microorganisms was also evaluated. The average age of the patients was 54.42 years, with a predominance of males (56.00%) and adults (66.00%). 41.75% (89/206) of the cultures were positive. In 72% (36/50) of patients, mixed cultures with bacteria and yeast were obtained. In bacteria, the observed resistance rate to all antibiotics was high (> 50.00%). All strains were multi-resistant. Antifungal resistance was variable according to the drug used, voriconazole (8.57%), fluconazole (3.57%); whereas, for caspofungin, total sensitivity (100.00%) was observed. The most frequent microorganisms were: Candida albicans Complex (17.45%), Acinetobacter baumannii/calcoaceticus Complex (15.30%) and Klebsiella pneumoniae (13.96%), results that show the predominance of these opportunistic pathogens as possible causes of colonization and / or co-infections in patients affected by COVID-19; as well as its manifest resistance to multiple antimicrobials
