Observations on the relevance of filterable forms of trypanosomes to latent infection of Trypanosoma evansi in mice

Abstract

An investigation of tissue forms of T. evansi and their relevance to latent infections. Organ transfers and filtration procedures were carried out before and after treatment. Filterable forms did not appear to be of importance in the maintenance of latent infections. Extravascular Trypanosomes were demonstrated in the choroid plexus by electron-microscopy. Such forms may have been too large to pass through the 0.8p pore size filter.
