Plate B was incubated 25 C and had a cell morphology of beige, cloudy thick lines and some cloudy thick dots. This eliminated the possibilities S. marcescens, B. subtilis, S. lutea, S. epidermidis, M. roseus, M. roseus, and C. sporogenes. S. marcescens colonies are red; M. roseus colonies are orange; S. lutea and M. luteus colonies are yellow; B. subtilis, C. sporogenes, and S. epidermidis colonies appear in white.2 This narrowed the possibilities to A. faecalis, P. fragi, and E. coli. All three
