Abstract

Whey from 17 women (four acutely infected with Toxoplasma gondii, eight chronically infected, and five uninfected) was studied. T. gondii-specific secretory IgA antibodies were demonstrated by ELISA in whey from acutely infected and one of eight chronically infected women. Such antibodies to tachyzoite proteins of < or = 14, 22, 26-28, 30, 46, 60, 70-80, and > 100 kD (eliminated by protease but not periodate or neuraminidase treatment) were demonstrated in whey from acutely infected subjects when Western blots were probed with their whey and antibodies to human secretory IgA or IgA or secretory piece. Secretory IgA from four of eight chronically infected women recognized the 46- and 69-kD epitopes. Other whey samples were negative. Incubation of T. gondii tachyzoites with whey or purified secretory IgA from acutely infected (but not seronegative) women caused 50-75% reduction in infection of enterocytes in vitro. Whey reactive with the 46-kD epitope from three of six chronically infected women caused less (> or = 40%) inhibition. Whey and purified secretory IgA from two of three acutely infected women agglutinated tachyzoites. Whey did not result in complement-dependent lysis of T. gondii. These results indicate that it may be possible to produce human secretory IgA to T. gondii capable of reducing initial infection of enterocytes, as such IgA is present during natural infection. They also demonstrate candidate epitopes for such protection.
