　 Biopsy from creeping disease (cutaneous larva migrans) of the abdominal skin, seen after eating imported loach 　
　 　 　 　

　

 　 The 1:500 diluted patient's own serum is reactive to the gut component of the nematode (indirect immunoperoxidase).　It seems that the gut component is much more immunogenic than the cuticles.
