Abstract:Electron microscopy is routinely used to identify viral infections in protozoan
parasites. These viruses have been described as non-enveloped and icosahedral
structures with a diameter of 30-60 nm. Most of them are classified within the
non-segmented dsRNA Totiviridae family. We observed virus-like
particles (VLPs) through transmission electron microscopy in the cytoplasm of
Trypanosoma cruzi epimastigotes grown in cultures. Clusters of
electrodense enveloped VLPs having a diameter of 48 nm were also observed.… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
