Sivun Bacillus kuva

Kuvaus:

This image depicted numbers of Bacillus anthracis bacterial colonies, which had been allowed to grow on sheep’s blood agar (SBA) for a 24 hour period. Note the classical appearance exhibited in the colonial morphology including a ground-glass, non-pigmented texture with accompanying comma projections from some of the individual rough-edged colonies. In this particular view, you’ll note that a tenacity test had been performed using an iinoculating loop, which proved positive for B. anthracis, causing the colony to ‘stand up’ like beaten egg white.
