Increasing evidence suggests that alterations in the gut microbiota are associated with the development, severity, and sequelae of COVID-19 infection.
Certain Gut Bacteria Can Inactivate COVID-19 Virus In a new study published in Cell Host & Microbe, researchers evaluated the impact of gut microbiota composition on respiratory viral infections through animal experiments.
The results showed that segmented filamentous bacteria in the gut could protect mice from viral influenza, respiratory syncytial virus, and the COVID-19 virus.
The SFB are unlikely to be the only kind of gut microbe capable of affecting the immune cells in the lungs, said Dr. Andrew Gewirtz, a co-senior study author, in a press release.
Research has shown that alterations in the gut microbiota, including changes in specific microbiota species and microbial-derived metabolites, play an important role in regulating the severity and progression of COVID-19 infection and post-recovery complications.
Viral Respiratory Tract Infection Affects the Gut Microbiota An analysis of fecal samples from 102 patients with severe COVID-19 infection following ICU admission found that decreased concentrations of gut microbiome metabolite-secondary bile acids and desaminotyrosine-were associated with an increased risk of respiratory failure and mortality.
Enhancing Gut Health to Build Robust Immunity The intestinal tract, the largest immune organ in the human body, plays a crucial role in establishing and maintaining a robust immune system, and gut immunity is closely linked to our diet.
