What is Anthrax? Symptoms. Its major virulence factors are plasmid-coded; however, recent studies have revealed chromosome-encoded virulence factors, indicating that the current understanding of its virulence mechanism is elusive and needs further investigation. A number of studies have indicated that plant-derived natural compounds are capable of significantly reducing the minimum inhibitory concentration of standard antibiotics by altering drug-resistance mechanisms of B. anthracis rods typically have dimensions of approximately 1 μm by 4 μm and may occur in chains resembling “boxcars” when observed under a microscope.
