Abstract
Immunomagnetic sorting, sequential filtrations, and counterflow centrifugal elutriation were compared for their ability to obtain enriched populations ofPneumocystis carinii developmental stages from infected rat-lung homogenates. Elutriation combined with sequential filtrations resulted in highly (>95%) enriched populations ofP. carinii cysts and trophozoites with excellent viability. This approach offers advantages over previously described methods of obtaining enrichedP. carinii cell populations and should have important applications to research on this organism.
