Compact Dry ETB
R (CD-ETB, ETB;
Enterobacteriaceae) , a ready-to-use and self-diffusible dry medium sheet culture system for the detection and enumeration of
Enterobacteriaceae, was evaluated. A total of 35
Enterobacteriaceae strains, which were studied for the inclusivity study, grew and formed red-purple colored colonies on the CD-ETB
R. When 17 gram-negative bacteria other than
Enterobacteriaceae were inoculated for the exclusivity study, 2 strains grew and formed red-purple colonies, 9 strains formed colorless colonies, and 6 strains failed to grow. A total of 43 gram-positive bacteria and 3 yeasts failed to grow. The CD-ETB method was compared with the Violet Red Bile Glucose (VRBG) agar method according to ISO 21528-2 and the 3M Petrifilm
TM EB (3M-EB
R) method in 53 meat samples. The correlation coefficients between CD-ETB
R and VRBG agar, CD-ETB
R and 3M-EB
R, and 3M-EB
R and VRBG agar were 0.962, 0.992 and 0.960, respectively.
