Nosocomial infection risks in critical illness: the microbiota-immune metasystem connection

An altered metasystem linking the gut microbiota and systemic immune response could lead to impaired host defense and increased vulnerability to hospital-acquired infections in cases of severe illness.

Arresting microbiota development stunts immune system maturation in mice

A recent study shows that microbiota maturation during weaning contributes to normal immune development and protection from infection.

Epsilon toxin-producing Clostridium perfringens colonize the gut of multiple sclerosis patients
