How anthrax spores grow in cultured human tissues. PNNL microbiologist Josh Powell looks at anthrax spores, which have developed into bacteria over the course of 12 hours. At low doses, researchers found growth of spores is lower in human lung cells than rabbits. PNNL microbiologist Josh Powell views anthrax bacteria and spores magnified 400 times.
