Step-by-step explanation:
Oral thrush is commonly caused by an overgrowth of the yeast Candida albicans in the oral cavity. It is most common in infants who have underdeveloped immune systems and in immunodeficient patients, such as those with AIDS. The infection is characterized by the appearance of white patches and pseudomembranes in the mouth, and it can be associated with bleeding.
Treatment for oral thrush may include topical antifungal medications like nystatin or clotrimazole, or systemic antifungal agents like fluconazole or itraconazole. In severe cases, amphotericin B may be used. The prevention of oral thrush involves maintaining good oral hygiene, avoiding irritants, and supporting the immune system.
