Obiect : To determine the antibodies against P. marneffei antigens in serum of Chiang Mai healthy population compared to HIV positive patients with penicilliosis marneffei. Method : Antibodies to secreted and sonicated form of P. marneffei anligens were determined by indirect ELISA technique. 103 Normal healthy sera and 9 H|V-positive patients with penicilliosis marneffei sera that diluted into l:1,000 with 0.05% PBS Tween were incubated with both forms of each 0.25 pg/ml antigens. Then

Results : The results demonstrated that 41 of 103 normal healthy sera (39.81%) were positive to sonicated form of P. marneffei anligen (A > 0.60) and 73 of 103 (70.88%) were positive to the secreted form. Three (33.33%) and five (55.55%) of HIV positive patients with penicilliosis marneffei were positive to sonicated and secreted form of this fungi antigen, respectively. Conclusion : The number of normal individuals hziving positive antibodies 1o both form of P. marneffei antigens in Chiang Mai population was not different from the HIV positive patients with penicilliosis marneffei.
