In response to these attacks, authorities worldwide increased their preparedness for dealing with bioterrorism. One major focus was to set up and improve procedures for the rapid and reliable detection (or exclusion) of relevant pathogens in samples suspected to contain such organisms. Because of a number of unique advantages, electron microscopy (EM) formed an integral part of these procedures. The Portuguese National Institute of Health through Emergency Response and Biopreparedness Unit (UREB) is prepared to recognize and respond to biological events, including bioterrorism, or catastrophes being responsible for the identification of the etiological agent.engBioterrorismBiological Tterrorist AttacksLaboratory DiagnosisPortuguese Reference LaboratoryPortugaljournal article10.1080/01913123.2016.1272645
