Growth characteristics of Acinetobacter baumannii isolates on Mueller–Hinton agar (a–c), and minimal amino acid defined Y- (d–f), TL- (g–i) and T- (j–l) media. Isolate 456MDp (a, d, g, j) shows normal growth on all media except Y (d), and produces pigment on Mueller–Hinton agar (a) and T-medium (j) only. Isolate 522A (b, e, h, k) shows normal growth with no pigment on all media. Strain ATCC 19606 (c, f, i, l) shows normal growth on all media and produces only slight amounts of pigment on T-medium (l).
