As populations have moved into cities, starting with the Industrial Revolution, they have lost exposure to the microbes in soil, dirt and animals often found in rural areas. The discovery of penicillin in 1928 and society’s increasing use of antibiotics has further disrupted microbiomes, scientists say. Children who take antibiotics early in life face a higher risk of child-onset asthma, celiac disease, obesity, attention-deficit hyperactivity disorder and other conditions, studies show. The heavy use of antibacterial cleaning products over the past few decades has also disrupted the microbiome and immune system development, scientists say. Birth by caesarean section—necessary in many cases—may also deprive babies of helpful microbes they would get from a vaginal birth. - https://www.wsj.com/articles/positive-microbes-microbiome-11615410244
