Electron microscopy (Viral infection)


Electron microscopy is primarily used for the detection of gastrointestinal viruses in stool samples, namely adenovirus, rotavirus, astrovirus and calicviruses. This rapid technique allows prompt diagnosis in sporadic and outbreak cases of diarrhoea and vomiting, facilitating the implementation of infection control measures. EM is also used for the routine screening of stool samples from immunosuppressed patients.
