A medium containing inorganic salts, vitamins and amino-acids is described for the in vitro cultivation of the amphistome, Orthocoelium scoliocoelium, from the rumen of buffalo. Based on the properties of rumen fluid, this medium promoted and sustained normal egg production, at 37°C temperature and pH 7·4 to 7·8 for 15 days. In contrast to other media used, no patho-physiological alterations except abnormal cytoplasmic lipid, were detected. Since the parasites produced normal eggs, it is concluded that this medium is suitable for short-term cultivation of the parasites.
