Talaromyces marneffei infection is a serious threat to immunocompromised patients and can be fatal if not diagnosed and treated promptly. The potential of mNGS in rapid and accurate diagnosis of T. marneffei infection is demonstrated in this case.
Talaromyces marneffei (T. marneffei), is an opportunistic pathogenic fungus commonly reported in southeast Asia. T. marneffei infection predominantly occurs in patients with immunodeficiency and can be fatal if diagnosis and treatment were delayed. Conventional diagnosis of T. marneffei infection relies heavily on tissue culture and histologic analysis, which is time consuming and has limited positive rate. Rapid and accurate diagnosis of T. marneffei remains urgent for effective therapy and prevention. This case is the first reported T. marneffei infection in non-HIV patients in north China diagnosed by mNGS. The successful diagnosis of T. marneffei infection assistant by mNGS underlies the potential of this technique in rapid etiological diagnosis. (C) 2021 The Author(s). Published by Elsevier Ltd.
