Infants with mucus-like stools can take oral probiotics, such as Mammazine and Clostridium Typhimurium diphtheriae capsules, and it is recommended to have a routine stool test to determine if there is inflammatory infection. In the case of bacterial enteritis, the stool is usually mucus-purulent and bloody, which requires the application of cephalosporins. In the case of viral enteritis, the stools are dilute watery stools, egg-flake soup-like stools, mucus stools, and the virus is self-limiting, so there is no specific medicine. If there is no enteritis in the stool test, it is caused by indigestion and needs to be regulated by diet. The mother should not eat cold and stimulating food for breast-fed babies, and parents need to pay attention to bottle sterilization and hand washing for formula-fed babies.
