This photograph depicts the colonial growth pattern displayed by Providencia alcalifaciens bacteria, which had been cultured on a Hektoen enteric (HE) agar medium. When grown on HE agar, P. alcalifaciens produces colonies very similar to those produced by Shigella spp., which are greenish-blue in color, and appear moist.
