The gut microbiome plays a dynamic role in initiating, conditioning and regulating the human immune response, and a significant portion of the body's immune cells are found in the gut, making the gut microbiome a critical player in regulating the immune response in the gut and other organs.
Studies have also highlighted evidence of gut-lung microbiome crosstalk, in which gut microbiota modulates lung immunity, and changes in gut microbiome composition have been linked to changes in immune responses and homeostasis in the lungs and increased susceptibility to respiratory diseases.
Gastrointestinal symptoms of COVID-19
Corona virus disease is primarily a respiratory infection, but it also affects the digestive system, and according to the “medical express” website report, digestive symptoms such as diarrhea, vomiting, nausea, loss of appetite, gastrointestinal bleeding and abdominal pain have been reported in Corona patients, and sometimes they are the only symptoms, Patients with disturbed gut bacteria may be at higher risk of contracting COVID-19.
Probiotics can prevent and treat respiratory infections
Probiotics have been used to prevent and treat respiratory infections caused by viruses, and several potential mechanisms have been postulated, including direct interaction of probiotic virus, production of inhibitory metabolites of viruses, and stimulation of the immune system through different signaling pathways.
