INTRASPECIFIC VARIABILITY OF PROTEOCEPHALUS-EXIGUUS LARUE, 1911 (CESTODA, PROTEOCEPHALIDAE) AS STUDIED BY THE RANDOM AMPLIFIED POLYMORPHIC DNA METHOD

The intraspecific variability of Proteocephalus exiguus, a common fish cestode, was studied by the random amplified polymorphic DNA method. Isolates from four distant localities and four host species were inves tigated using eight arbitrary decamer oligonucleotides as primers. A r elatively high variation of RAPD finger prints from individual strobil a was detected. The constant fragments observed in all isolates detect ed by eight primers characterized the species studied.
