Solution
Both pseudomembranous colitis and thrush can result when antibiotic therapy disrupts the normal microbiota.
Here's why:
-
Antibiotics are designed to kill harmful bacteria in the body, but they can also disrupt the balance of normal microbiota, the community of microorganisms that live in our bodies.
-
Pseudomembranous colitis is a severe inflammation of the colon that can occur after the normal gut flora is eradicated by antibiotics. The bacteria Clostridium difficile, which is normally kept in check by the gut flora, can overgrow and produce toxins that cause damage to the colon.
-
Thrush, or oral candidiasis, is a fungal infection that can occur when the balance of microorganisms in the mouth is disrupted. Antibiotics can kill off the bacteria that normally keep the Candida fungus in check, allowing it to overgrow and cause infection.
-
Black hairy tongue and anaphylactic shock are not typically associated with disruption of the normal microbiota by antibiotics. Black hairy tongue is a condition that can be caused by poor oral hygiene, tobacco use, or certain medications, but not usually antibiotics. Anaphylactic shock is a severe allergic reaction that can occur in response to medications, including antibiotics, but it is not caused by disruption of the normal microbiota.
