First bacteria we ever meet can keep us out of hospital

New study shows that the first bacteria encountered after birth could reduce the risk of young children being hospitalized with lung infections by 50%. Bifidobacterium longum, found in newborns, showed a protective effect, potentially influencing the developing immune system. The research suggests that early microbiome composition could play a crucial role in preventing infections, emphasizing the importance of interventions to promote beneficial bacteria in infants.
