Microorganisms known as the normal flora or the normal microbiota reside on and in the body tissues and fluids without causing any disease. Normal microbiota through microbial antagonism protect against pathogens. Microbial antagonism contributes to the first line of defence since resident microbiota compete for nutrients and oxygen, limiting availability for pathogens. Crohn's disease or the inflammatory bowel disease is thought to arise from abnormal immune response to either food or normal microbiota resulting in the inflammation in the digestive tract. Broad spectrum antibiotics that are used for antimicrobial therapy reduce or wipe out the normal flora of the body. This provides an opportunity for the pathogenic organisms to cause a new infection. A superinfection can prevail if the resident microbiota are wiped out when broad spectrum antimicrobial therapy is used for treating an infection. So, the correct options are A, C, and D.
