Abstract

To elucidate the immune relations between mother and the newborn fry in guppy Poecilia reticulata, mother guppies were immunized by intraperitoneal injection with formalin-killed Aeromonas hydrophita and agglutinating antibody titers and precipitating antibody in body fluid of mother guppies and the newborn fry were investigated.<br> Agglutinating antibody in the body fluid of the immunized mother guppies appeared from 7 to 84 days after immunization. The antibody titers in mother guppies increased ranging from 1:32 to 1:64 four weeks after immunization. Agglutinating antibody in the body fluid of newborn fry borne by immunized mother guppies was detected from 14 to 75 days after mother guppies were immunized. The antibody titers in newbom fry increased ranging from 1:16 to 1:32 about five weeks after mother guppies were immunized. Each body fluid of immunized mother guppy and the newborn fry showed a precipitin line formation against sonicated A. hydrophila.<br> The above-mentioned results suggested that the antibody was transmitted from mother guppy to fetus.
