Crynodeb

A syndinian parasite of the genus Hematodinium was detected in tissues and haemolymph of Scottish shore crabs (Carcinus maenas) and Norway lobsters (Nephrops norvegicus) by PCR. Analysis of conserved and variable regions of the ribosomal RNA gene found homology in 18S and 5.8S, and high similarity (> 97%) in ITS1 and ITS2, thus indicating that these parasites belong to the same species. Microscopy of the parasites in the haemal sinuses of Scottish C. maenas revealed morphological similar life-cycle stages to Hematodinium perezi identified in C. maenas in 1931 by Chatton and Poisson, and to Hematodinium sp. detected in N. norvegicus.
