Fig 1. A, The typical dry, lactose-positive Escherichia coli growing on MacConkey
(MAC) agar. Note the pink precipitate surrounding the individual colonies. B, Mucoid
colonies of E. coli growing on MAC agar. C, Non–lactose-fermenting E. coli compared
with typical lactose-fermenting E. coli on MAC agar.

Fig 2. Comparison of the colony morphology of
Escherichia vulneris and a yellow-pigmented Escherichia
hermannii on MacConkey agar. Escherichia vulneris may also
produce a yellow-pigmented colony, but the yellow is more
prevalent in E. hermannii.

Fig 3. Mucoid appearance of Klebsiella pneumoniae
on MacConkey agar.

Fig 4. Yellow-pigmented Pantoea agglomerans
(formerly Enterobacter agglomerans) on a sheep blood agar.

Fig 5. A, Serratia marcescens growing on a sheep blood agar plate (left) and
showing brick-red pigment when grown on MacConkey (MAC) agar (right). B, Pinkish red
pigmentation of Serratia rubidaea growing on MAC.

Fig 6. Example of Proteus mirabilis swarming on a
sheep blood agar plate.

Fig 7. The antigenic structures of salmonellae used
in serologic typing.

Fig 8. Left, Lactose-negative appearance of
Shigella sonnei growing on MacConkey (MAC) agar at 18 to
24 hours of incubation. Right, Lactose-positive appearance of
S. sonnei growing on MAC after 48 hours of incubation.

Fig 9. A, Blue-violet pigment of Kluyvera spp. growing on sheep blood agar.
This Kluyvera sp. resembles the colony morphology of Escherichia coli growing
on MacConkey (MAC) agar. B, Appearance of K. cryocrescens growing on MAC.
C, Appearance of K. ascorbata growing on MAC agar.

Fig 10. Clear, green colonies of Shigella growing on
Hektoen enteric (HE) agar.

Fig 11. Hydrogen sulfide–producing colonies of
salmonellae growing on xylose-lysine-desoxycholate agar.

Fig 12. Salmonella growing on CHROMagar
Salmonella differential agar.

Fig 13. lowchart for the presumptive identification of commonly encountered
Enterobacteriaceae on triple sugar iron (TSI) agar. K, alkaline; A, acid; PAD,
phenylalanine deaminase; IMV:C, indole, methyl red, Voges-Proskauer, citrate; NLF,
nonlactose fermenter.
