One hundred Ancylostoma caninum, in groups of 10 in a special apparatus, were offered dog blood and serum, NaCl, Krebs-Ringer bicarbonate, polyvinylpyrrolidone, intestinal epithelial extracts, heated serum, and dialyzed and nondialyzed fractions of serum. The worms' rate of suction was measured. They sucked actively only in blood, serum, and nondialyzed fraction of serum. These findings suggest that dog serum contains one or more macromolecules which stimulate the worm to suck actively. |
