Which opportunistic fungus is known to affect immunocompromised individuals?

The opportunity for certain fungi to cause infections is markedly increased in individuals with compromised immune systems. Candida albicans is one of the most common opportunistic fungi associated with infections in such patients. It can lead to various conditions, including oral thrush, esophagitis, and systemic infections, particularly in individuals who are immunocompromised due to conditions such as HIV/AIDS, chemotherapy, or prolonged steroid use.

Candida albicans is typically part of the normal flora of the human body, residing in the gut and on mucous membranes. However, when the immune system is weakened, this normally benign organism can overgrow, leading to significant infections. This phenomenon highlights the importance of maintaining careful observation and management of infections in at-risk populations.

While the other fungi mentioned also pose risks to immunocompromised individuals, Candida albicans is most commonly associated with opportunistic infections in these patients, making it the most representative option in this context.
