A novel method for the isolation of nematode larvae using pluronic F-68-treated cellulose strips.
A new method is described for the isolation of cultured nematode larvae. This allows effective separation of larvae from fecal contamination, exsheathed larvae from cast sheaths, and viable larvae from nonviable larvae. The method involves the use of cellulose strips and has been assessed using larvae from 2 hookworm species, Necator americanus and Ancylostoma ceylanicum. Pretreatment of the cellulose strips with 1.0% (w/v) of the nonionic surfactant, Pluronic F-68, significantly increased larval recovery of both species.
