title: Acanthamoeba culbertsoni and Naegleria fowleri: occurrence of antibodies in man.
abstract: Serum samples of 1,054 inhabitants of Bohemia (Czechoslovakia) were examined by means of indirect haemagglutination test with antigens from Naegleria fowleri and Acanthamoeba culbertsoni. With N. fowleri antigen the frequency of positive reactions did not exceed 3.5 per cent in lowest serum dilutions only. N. fowleri could not be identified as a possible causative agent in any chronic form of disease in man. Significant accumulation of positive findings with A. culbertsoni antigen was observed in hepatitis A patients and convalescents (52 per cent). The potential interpretations of this phenomenon are discussed.
