Bacteriological Identification. Three colony types were recovered on SP-4 agar (panel a). Each type was identified as a distinct organism, as shown by Gram stain in panels (b-d). S. acidominimus (c) and P. caecimuris (d) showed classic morphology and arrangements of their respective genera. The novel Gemella species (‘G. muriseptica’) were Gram positive diplococci (Panel b inset, arrow), and bacteria tended to aggregate serum proteins present in the SP-4 broth
