Under a magnification of 500X, this photomicrograph revealed the presence of a filamentous microcolony of Actinomyces israelii bacteria, strain W-838, serotype-2, which had been incubated on brain heart infusion (BHI) agar, for a 48-hour time period. See PHIL 21808, for a depiction of a colony, said to appear more mature than the one you see here.
