TEMTransmission Electron Microscopy as a “Catch-All” Tool

 

Comprehensive Viral Screening of G.I. Viruses

The seven viral groups that can be identified in stool specimens by transmission electron microscopy include: Rotavirus, Adenovirus, Astrovirus, Norovirus (Norwalk-like Virus), Sapovirus, Pico/Parvoviruses and Enteric Coronavirus. The enteric coronaviruses can resemble classic respiratory-type viruses with a “corona” of protruding peplomers, or a more pleomorphic type with a flexible fringe like the Toroviruses (the type usually observed in Arizona and other dry, warm climates around the world).

RECOMMENDATIONS OF TESTS FOR THE DIAGNOSTIC TESTING OF STOOL SPECIMENS: Laboratories that exclusively use PCR Multiplex Screens to measure microbial agents in stool specimens may be missing important causes of infections [Enteric Coronavirus/Torovirus, small round viruses (picornaviruses, parvoviruses)]. They should include Transmission Electron Microscopy (whole mount/negative contrast technique) to ensure a more complete analysis of possible causative agents.
