Final answer:
Broad-spectrum antibiotics can lead to superinfections, such as candidiasis and aspergillosis, due to the disruption of normal microbiota.
Step-by-step explanation:
Using broad-spectrum antibiotics can increase the risk of fungal infections because they may kill off protective microbiota, leading to superinfections. The two fungal infections that commonly develop as a result of antimicrobial usage are candidiasis and aspergillosis. Candidiasis is a yeast infection that may affect various body parts, including the mouth (oral thrush) and vagina, while aspergillosis is primarily a systemic infection affecting the respiratory systemThis intervention is crucial if given within 3-4 hours of the onset of stroke symptoms, significantly improving the patient's prognosis.
