Abstract: Cellular polyamines of nematodes of the phylum Nematoda, planarians, cestodes and trematodes of the phylum Platyhelminthes, earthworms, leeches and sandworms of the phylum Annelida, and hydras of the phylum Cnidaria, were analyzed by HPLC and GC to obtain phylogenetic informations and parasitic peculiarities on polyamine profiles in lower invertevrates. Spermidine and spermine were ubiquitously distributed in four zoo-parasitic nematodes. A plant parasite, Pratylenchus and a fungivore, Bursaphelenchus and two entomopathogens, Steinernema as well as free-living bacteriovores, Caenorhabditis and Dorylaimus, contained spermidine and lacked spermine. Zoo-parasitic cestodes Hymenolepis and Diphyllobothrium, and zoo-parasitic trematodes Paragonimus, Fasciola and Schistosoma, belonging to the phylum Platyhelminthes, ubiquitously contained spermidine and spermine, suggesting their dependence on host animals for uptake of spermine. Putrescine, cadaverine, spermidine and spermine were the major polyamines in freshwater, marine and land planarians (the phylum Platyhelminthes), and free-living earthworms, leeches and sandworms (the phylum Annelida). Hydras belonging to the phylum Cnidaria contained putrescine and spermidine alone. Homospermidine was distributed in a zoo-parasitic helminth of the phylum Nematoda and two zoo-parasitic tapeworms of the phylum Platyhelminthes as well as planarians, earthworms and leeches. Norspermidine and/or norspermine were found in two land planarians, a leech and a sandworm. This is the first report on the occurrence of these novel polyamines within lower invertebrates.
