Abstract: Aim To study the pathogenicity of toxigenic spine of Eucleid Caterpillar.Methods With the method of pricking on the epiderm the skin of volunteers was touched directly by toxigenic spine of mature Eucleidae Caterpillar and inoculated directly by the abstergent liquid of toxigenic spine on their upper limbs so that we could observe the toxicity of toxigenic spine continuouesly. Results The sympotoms of twinge,titillation, red halo,urticaria and papular eruption were manifested on the local skin of upper limbs of volunteers after being touched by toxigenic spine of Eucleid Caterpillar. The dermatitis symptom on the skin of upper limbs of volunteers after being vaccinated directly by the abstergent liquid of toxigenic spine was similar to that of volunteers after being touched directly by toxigenic spine. However,if the skin of volunteers vaccinated by the abstergent liquid of toxigenic spine which had been boiled, the dermatitis sympom didn't occure. Conclusions The Eucleidae Caterpillar have obvious pathogenicity. The material component of pathogenicity is protein toxin and its toxicity is stronger.
