Anthrax caused by Bacillus anthracis is one of the most important zoonotic diseases in the worldwide. To control and prevent the disease effectively, several methods such as development of a fast and specific diagnostic method and vaccine, education etc, have been carried out. However, it still has a problem in the control and prevention. To control, the most important method is the prevention of direct or indirect contact of the causative agent with susceptible host. Therefore, we developed a fast and specific detection method, polymerase chain reaction, of B anthracis from soil and infected animals because the organism could survive long time in the environment including soil due to formation of spore. With the method, virulence genes of B anthracis were successfully amplified from experimentally infected soil and mice. Up to 4.2 × 10 of the organisms per gram could be detected with the PCR method from experimentally infected soil. These results suggested that this PCR method could be effectively used not only to detect B anthracis in soil and infected animal but also to provide the information to prevent the disease.
