إنجليزي. The author carries out the study of a vaccine prepared with a Sterne avirulent "B. anthracis" strain 34F2, under the point of view of innocuity, immunity power and validity. He studies also the effect of the lyophilisation on the strain's maintenance. The vegetative form is perturbed in its sporulative capacity and must be lyophylised in sporular form. Thanks to the vaccine, used in prophylaxis campaigns in Portugal, anthrax was pratically eradicated from domestic animals and, as a consequence, from man. Nowadays, anthrax appears only in a sporadic form
