Single colony morphotypes, on NAG medium. a S. rubidaea R and W forms; b S. marcescens F, Fw, and M forms; and c E. coli . Left: colony appearance at maturity (7–9 days), with schemes of colony cross-sections. All Serratia colonies show terminate growth: final diameter is about 15 mm in F, Fw, and M, 20 mm in R and W. Right: development of colony margins at days indicated (free agar is at the right).
