<prompt> Answer this question truthfullyIn what type of patients can Malassezia furfur cause more problems than just Pityriasis Versicolor?  <response>: <reason> Malassezia furfur can cause many more problems, other than just Pityriasis Versicolor, in immunocompromised patients. This is because Malassezia furfur is a type of yeast that is normally found on the skin, but can cause infections in individuals with weakened immune systems. In addition to Pityriasis Versicolor, Malassezia furfur can cause a range of other skin and systemic infections, including sepsis, pneumonia, and meningitis. Immunocompromised patients, such as those with HIVAIDS, cancer, or who are undergoing immunosuppressive therapy, are at a higher risk for these types of infections and should take extra precautions to avoid exposure to Malassezia furfur.
