Cryopreservation of sheathed third-stage larvae of Ancylostoma caninum (hookworm of dogs) and Ancylostoma tubaeforme (hookworm of cats)

Abstract

Sheathed infective third-stage larvae of Ancylostoma caninum and Ancylostoma tubaeforme were successfully cryopreserved in liquid nitrogen. The survival rates, as assessed by motility, were A. caninum 49,2% and A. tubaeforme 51 ,5% after 30 d of cryopreservation .The articles have been scanned in colour with a HP Scanjet 5590; 600dpi. Adobe Acrobat X Pro was used to OCR the text and also for the merging and conversion to the final presentation PDF-format.mn201
