Explain how disruptions in normal microbiota can lead to infections
What will be an ideal response?
When an antibiotic is used, it may kill many types of benign resident bacteria along with the pathogen being targeted. With normal microbiota reduced, opportunistic pathogens are able to establish infections. A common example of this is when a woman takes antibiotics to treat a urinary tract infection (UTI), only to develop a vaginal yeast infection soon after the antibiotic therapy concludes. The yeast Candida albicans is an opportunistic pathogen that is usually present in the vagina. Its growth is kept in check by the normal microbiota of the vagina. Thus, when the vaginal normal microbiota is disrupted, the yeast has an opportunity to thrive and cause symptoms. Similarly, diarrhea is a common side effect of antibiotic therapies, likely due to how our gut microbiome is affected.
