COMPOUNDS FOR THE PREVENTION AND TREATMENT OF HELMINTH INFECTIONS

摘要

A compound for protecting a vertebrate against infection by helminths comprising hyaluronidase covalently coupled to an immunostimulating carrier, in preferred form, the immunostimulating carrier to which the hyaluronidase is covalently coupled comprising a copolymer of ethylenepiperazine N-oxide and N-ethylacetylethylenepiperazinium bromide (hereafter referred to as "synpol"), and a process for protecting a vertebrate against infection by helminths comprising administration to the vertebrate of a therapeutically effective amount of a compound comprising hyaluronidase covalently coupled to an immunostimulating carrier, preferably synpol, in preferred form, the compound being administered to the vertebrate in the form of vaccine which includes, in admixture with the compound, synpol, and a process comprising reacting hyaluronidase and an immunostimulating carrier under conditions of time and temperature to covalently couple hyaluronidase and said immunogenic carrier.
