 This study examined the differences in the lung microbiomes of COVID-19 patients and non-COVID-19 patients. The researchers found that COVID-19 patients had significantly different microbial communities than those without the virus, with more opportunistic pathogens such as acenetobacter bamanii and candida species being present at higher levels. These pathogens were also linked to increased inflammatory markers, suggesting that they could play a role in the progression of the disease.
