Abstract
Carp, Cyprinus carpio L., is one of the most important cultured fish, especially in Central Europe and Asia. In Europe, it is infected with a large number of parasites, many of them introduced from Asia, mainly from the Far East of Russia and China. Parasitic worms, i.e. helminths, are represented, among others, by tapeworms (Cestoda) including the most pathogenic species, the Asian fish tapeworm Bothriocephalus acheilognathi Yamaguti, 1934 (syn. B. gowkongensis Yeh, 1955), recently placed in the order Bothriocephalidea. Other potentially pathogenic cestodes of carp belong to the order Caryophyllidea, the species of which possess a monozoic (only one set of genital organs) and unsegmented body and use tubificid oligochaetes as intermediate hosts. Khawia sinensis Hsu, 1935 (Caryophyllidea: Lytocestidae), is native in East Asia and was described from the vicinity of Beijing in China (Hsu, 1935). It successfully colonized a major part of Europe and was also imported to North America. However, the veterinary importance of K. sinensis has decreased considerably during the last few decades, possibly as a result of the more recent introduction of Atractolytocestus huronensis Anthony, 1958 (Lytocestidae), to Europe. In this paper, another caryophyllidean cestode, Khawia japonensis (Yamaguti, 1934), which occurred originally in East Asia, is reported from Europe for the first time.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
