Observations on certain Conditions Requisite for Skin Penetration by the Infective Larvæ of Strongyloides and Ankylostomes

Abstract

Our knowledge that the infective larvæ of certain parasitic nematodes are capable of actively boring into intact skin and of thus gaining entry into the host dates from the epoch-making discovery of Looss, who, in 1897, accidentally infected himself with Ancylostoma duodenale, the mature larvae of which entered through the skin of his hand (Looss, 1911, pp. 456−459).
