This research aimed to understand how common a specific type of bacteria, called Escherichia coli ST131, is in healthy children. This bacteria is known for being resistant to many antibiotics and can cause serious infections. The study found that about 25% of healthy children carried the E. coli ST131 bacteria in their intestines. This bacteria was found more frequently in clinical samples (samples taken from sick children) than in the stool of healthy children. Children who had siblings were more likely to carry this bacteria. However, children born by cesarean section were less likely to carry it. E. coli ST131 showed high resistance to common antibiotics, making it harder to treat infections caused by this bacteria. The high rate of E. coli ST131 in healthy children suggests that they can carry and potentially spread this resistant bacteria within the community without showing any symptoms. This finding highlights the importance of monitoring and controlling the spread of antibiotic-resistant bacteria.
