ABSTRACT: The cloning and sequencing of the small subunit (SSU) ribosomal DNA gene from Kudoa rosenbuschi (myxosporean species associated with post-mortem myoliquefaction process in the Argentinean hake Merluccius hubbsi) is reported. The
SSU rDNA was found to contain 1740 bp with a single polymorphic site with either a C or T at position 221. The sequence data obtained in this study and those known sequences of Kudoa species deposited in the GenBank were all analyzed to construct a
phylogenetic tree. Nucleotide sequences showed the highest degree of identity with K. funduli, followed by K. miniauriculata, K. clupeidae and K. dianae. Phylogenetic analysis placed K. rosenbuschi in the same branch of
K. clupeidae and K. funduli, and showed it to be closely related to K. dianae, K. paniformis and K. miniauriculata.
