Abstract
Trichosporon asahii (T. asahii) is an opportunistic pathogenic fungus that often causes severe infections in immunosuppressed patients. Among Trichosporon species, T. asahii is the most pathogenic and lethal species. Current research faces challenges related to unknown pathogenic mechanisms, complex resistance mechanisms, insufficiently rapid and accurate diagnostic methods, and insufficient research on susceptibility to infection. These issues need to be explored in depth. This review summarizes research progress on the origin and classification of T. asahii, its virulence factors and pathogenic mechanisms, epidemiological characteristics, infection modes, diagnostic methods, drug treatment options, and drug resistance mechanisms. Traditional culture combined with molecular biology techniques, such as polymerase chain reaction and gene sequencing, has improved the accuracy and speed of detection. Treatment relies mainly on azole antifungal drugs and amphotericin B; however, patients are facing the problem of drug resistance. New techniques, such as gene knockout and gene sequencing, have identified resistance mechanisms, thus supporting the development of novel antifungal drugs. In summary, an in-depth study of T. asahii will aid in developing more effective diagnostic and therapeutic methods and improve patient prognosis.
