In vitro culture of Neoechinorhynchus buttnerae (Acanthocephala: Neoechinorhynchidae): Influence of temperature and culture media.

Infection by the acantocephalan Neoechinorhynchus buttnerae is considered one of most important concerns for tambaqui fish (Colossoma macropomum ) production. Treatment strategies have been the focus of several in vivo studies; however, few studies have been undertaken on in vitro protocols for parasite maintenance. The aim of the present study was to develop the best in vitro culture condition for N.
