[Bacteriological inhibition in the nests of Acromyrmex octospinosus Reich].
Media prepared from nests of Acromyrmex octospinosus Reich show an inhibiting activity against strains of bacteria Gram + and Gram -. To demonstrate this activity it is necessary to use a particular methodology using important concentration of extract (Mass effect). The main reason of the inhibition is due to the acidity of pH (pH = 5.0). This effect explains how the ants protect their nest against the bacterial competitors.
