Just stressing to the OP that if you do go down a long/steep hill in B mode (or even in Drive) the engine will start to rev and sometimes rev loudly. It is normal and not a fault. Also, when you reach the bottom of the hill and stop at a traffic light, the engine might carry on revving away for a short time.
Summary. Bacillus anthracis possesses three primary virulence factors: capsule, lethal toxin (LT), and edema toxin (ET). Dendritic cells (DCs) are critical to innate and acquired immunity and represent potential targets for these factors. We examined the ability of B. anthracis spores and bacilli to stimulate human monocyte-derived DC (MDDC), primary myeloid DC (mDC), and plasmacytoid DC (pDC) cytokine secretion.
A virulence factor is any property of a bacterial cell that allows the bacterium to infect another organism. Pili are considered virulence factors because they allow bacterial cells to adhere to tissues and can help the bacterial cells resist attack from immune cells in the human body.
