| Diagnosis of Kudoa nova infecting the skeletal muscle tissue of round gobiid Neogobius melanostomus collected in the Sea of Azov was done by adding molecular data to the demographic and morphological characterizations of the parasite. The small subunit (SU) ribosomal DNA sequence analysis revealed Kudoa nova cluster within clade that includes Kudoa paniformis, Kudoa dianae, Kudoa sp., Kudoa miniauriculata, Kudoa alliaria and Kudoa rosenbuschi. Results on the molecular sequence data of Kudoa nova provide new evidence to discuss the hypothesis of tissue tropism playing an important role in the radiation of kudoids. |
