Terbinafine is a synthetic antifungal agent which has recently been found to be highly effective against Pneumocystis carinii. This study evaluated the efficacy of terbinafine on rat P. carinii antigenic profile and the immune response by Western blot analysis, in comparison with atovaquone and co-trimoxazole in rats with pneumocystosis. Terbinafine was shown to target two specific major antigens, particularly those of 116 and 35-40 kDa. Antibodies reactive against these moieties were found in all rats treated with atovaquone and co-trimoxazole, but not in those treated with terbinafine. These surface antigen modifications could be related to disease severity and could provide additional information for monitoring the efficacy of this treatment.
