^♠ ∗  denotes a significant and ns a nonsignificant difference relative to the control, standard inoculation, evaluated two hours after inoculation, according to the bilateral Dunnett test (p < 0.05). All values followed by ∗ were significantly superior to the control; ns means not significantly different from control. Values not followed by ∗ or ns were not compared.
