Separation of cryptosporidium oocysts from fecal debris by density gradient centrifugation and glass bead columns.
A method was developed to obtain purified cryptosporidium oocysts from fecal samples. Oocysts were initially collected by centrifugation through a sucrose density gradient and further purified by passage through glass bead columns. The purified oocysts were antigenically active and sufficiently pure for immunological studies.
