Abstract
KLECZKOWSKA1 has described a ‘physiological ageing’ of colonies of Rhizobium in an agar layer which renders them immune to attack by bacteriophage after they are 19 hr. old. Thus the multiplication and spread of the phage particles throughout the volume of the plaque must take place within the period set by the ageing of the bacterial colonies.
