A scanning electron microscope technique for studying the sclerites of Cichlidogyrus

Fannes W, Vanhove MPM, Huyse T & Paladini G (2015) A scanning electron microscope technique for studying the sclerites of Cichlidogyrus, Parasitology Research, 114 (5), pp. 2031-2034.

The genusCichlidogyrus(Monogenea: Ancyrocephalidae) includes more than 90 species, most of which are gill parasites of African cichlid fishes.Cichlidogyrushas been studied extensively in recent years, but scanning electron microscope (SEM) investigations of the isolated hard parts have not yet been undertaken. In this paper, we describe a method for isolating and scanning the sclerites of individualCichlidogyrusworms. Twenty-year-old, formol-fixed specimens ofCichlidogyrus casuarinuswere subjected to proteinase K digestion in order to release the sclerites from the surrounding soft tissues. SEM micrographs of the haptoral sclerites and the male copulatory organ are presented. The ability to digest formol-fixed specimens makes this method a useful tool for the study of historical museum collections.
