Characterization of four novel actinospore types of fish parasitic myxozoans and the occurrence of Branchiodrilus hortensis and Ophidonais serpentina from fish farms of Hungary.

ABSTRACT: Six distinct actinospore types were identified in the intestinal epithelium of oligochaetes collected from the Szigetbecse and Makád fish farms of Ráckeve Danube Arm Fishing Association, in Hungary. Four new types: triactinomyxon type, raabeia type, aurantiactinomyxon type 1, and aurantiactinomyxon type 2, were described morphologically and molecularly from three invertebrate host species: Limnodrilus hoffmeisteri, Ophidonais serpentina, and Tubifex tubifex. The 18S ribosomal DNA (rDNA) analysis revealed that these new types of actinospores did not match any myxospore sequences available in GenBank. Phylogenetic analysis placed the triactinomyxon type within the Myxobolus clade that parasitizes cyprinid fish, while the raabeia type and aurantiactinomyxon type 2
