How some gut bacteria avoid immune surveillance

The immune system tolerates flagellins of commensal bacteria while mounting an immune response against flagellins produced by pathogens.

Obese mice are protected against genital herpes — thanks to their microbiota

The findings of a new research suggest that obesity-induced changes in the vaginal microbiota can affect the immune responses against viral infection.

COVID-19 may disrupt gut microbiota to increase risk for other infections

Microbiota alterations in COVID-19 patients appeared to be associated with secondary infections of the blood by gut bacteria: four cases of positive blood cultures of Staphylococcus species were identified.

COVID-19 in children: nasal microbiota as a possible ‘shield’ protection

Moraxella may be involved in protecting children from COVID-19 infections through its action on amino acid and lipid metabolism in the upper respiratory tract.

Recurrent infections and estrogen can shape the urogenital microbiota

New research indicates that recurrent urinary tract infections and estrogen can shape the urogenital microbiota in ways that may protect against recurrent infections.

COVID-19 may alter lung microbiota and reduce immunity, facilitating secondary infections

COVID-19 alters the local immunity of the lung in ways that weaken the body’s antimicrobial defense and facilitate the development of secondary infections.

Specific antibodies in breast milk may help to fight intestinal infections

The findings of a new research suggest that IgG in breast milk promotes immunity against intestinal pathogens and shapes the development of the gut microbiota and immune cells in early…

Early viral encounters may affect airway microbiota, lead to recurrent respiratory infections

Early viral encounters are associated with disadvantageous immune and microbiota profiles, as well as recurrent respiratory infections. A new study published in Nature Microbiology claims.

How the human microbiota can influence respiratory health

Profiling the bacteria and viruses residing in the human body could help to diagnose different pathogens and develop new targeted interventions.

Molecules from dying gut cells fuel bacterial growth
