Parachaenichthys charcoti

Both of the two examined specimens of the Antarctic dragonfish appeared to be infected with the larvae of two nematode species ( Pseudoterranova sp. and Contracaecum sp. ) and three species of cestodes: bilocular and trilocular metacestodes, and Diphyllobothrium sp. ; from 10 to 12 helminth species parasitized one fish. The trematodes N. georgiensis and L. macrocotyle were found in both host specimens, while L. garrardi was in one fish. Acanthocephalans were represented by adults of A. megarhynchus and M. rennicki (both in one host), and cystacanths of three species of the genus Corynosoma : C. hammani and C. evae in both hosts, and C. bullosum in one host. Among 13 helminth species collected from Antarctic dragonfish, bilocular metacestodes were the most abundant (table 2), and due to this cestodes predominated the community comprising 72.2 % of all helminths collected.
