متن کاملX-cells in pseudotumors of yellowfin goby Acanthogobius flavimanus: a protistan organism distinct from that in flathead flounder Hippoglossoides dubius.
Yellowfin goby Acanthogobius flavimanus affected with X-cell pseudotumors were sampled from a river estuary in Tokyo Bay, Japan. We amplified the gene for small subunit ribosomal RNA (18S rRNA) of X-cells of the goby with PCR using universal primers. The gene that we obtained (DDBJ Accession no.
