Detection and identification of coronaviruses in human tissues using electron microscopy.

ABSTRACT: The identification of viral particles within a tissue specimen requires specific knowledge of viral ultrastructure and replication, as well as a thorough familiarity with normal subcellular organelles. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has underscored how challenging the task of identifying coronavirus by electron microscopy (EM) can be. Numerous articles have been published mischaracterizing common subcellular structures, including clathrin- or coatomer- coated vesicles, multivesicular bodies, and rough endoplasmic reticulum, as coronavirus particles in SARS-CoV-2 positive patient tissue specimens. To counter these misinterpretations, we describe the morphological features of coronaviruses that should be used to differentiate coronavirus particles f
