The behaviour of infective <i>Ancylostoma caninum</i> larvae in serum gradients

Abstract

Experiments were carried out to investigate if sera of animal species other than dog are chemotactically active for infective larvae of Ancyclostoma caninum. those sera were also found to contain such a factor(s), although the larvae were attracted significantly better by dog serum. How this chemotaxis might be applied to the in vivo situation, when infective A. caninum larvae penetrate the skin of dogs, is discussed.
