Abstract
Recent interest in anthrax is due to its potential use in bioterrorism and as a biowarfare agent against civilian populations. The development of rapid and sensitive techniques to detect anthrax spores in suspicious specimens is the most important aim for public health. With a view to preventing exposure of laboratory workers to viable Bacillus anthracis spores, this study evaluated the suitability of PCR assays for detecting anthrax spores previously inactivated at 121°C for 45 min. The results indicate that heat treatment ensures the complete inactivation of B. anthracis spores without significantly affecting the efficiency of PCR assays.
